The head is concealed from above. Their antennae are elbowed and distinctly clubbed on the end. Where does the female bark beetle lay her eggs? ------CORRECT ANSWER---------------Under the inner bark of the live tree, in the cambium layer. She creates an egg gallery for this purpose (A deeper tunnel where the female lays her eggs). What is another name for the bark beetle and why? ------CORRECT ANSWER---------------The Engraver Beetle. Because as the eggs hatch, the larvae make their own picturesque tunnels that radiate out from the egg gallery creating an interesting 'engraving'. What ant is the largest structural pest ant in the US? ------CORRECT ANSWER---------------The Carpenter Ant What is the life cycle of a Carpenter Ant? ------CORRECT ANSWER---------- -----They swarm in early spring and late summer. They mate in the air, and the male dies. The mated female's wings break off and she burrows into wood for nesting. Where are some areas a carpenter ant might nest? ------CORRECT ANSWER---------------Outside in stumps, logs, under stones. Extending into the home they may nest in wall voids, hollow flush panels doors, termite galleries in wood, stored furniture, foamed plastic, and fiberglass insulation. What are some distinguishing factors of the Carpenter Ant frass? ------ CORRECT ANSWER---------------It is similar to sawdust with dead bugs mixed in. They make slit-like openings in the wood to expel the frass. Galleries are very clean because they expel most of the frass from the galleries. Do the Carpenter Ant Larva do damage to wood?!? ------CORRECT ANSWER---------------No. How many nodes does a Carpenter Ant have? ------CORRECT ANSWER--- ------------1 node What kind of wood does a carpenter bee prefer? ------CORRECT ANSWER---------------Softwoods. Especially attracted to California redwood, cypress, cedar, white pine, and southern yellow pine. They will avoid well- painted wood. How does the wood become decayed? ------CORRECT ANSWER------------ ---If the moisture content of the wood nears 28%-30% for any appreciable amount of time, decay fungi spores which are present in the air will attack it. 20% moisture content is generally considered safe standard and will generally not allow for fungi spores to attack. How does the wood decay (fungi) grow? ------CORRECT ANSWER----------- ----The germinating spores send out tiny, usually microscopic growing strands called hyphae. Masses of hyphae are called mycelia. The mycelia use an enzyme to penetrate the wood and then go from cell to cell of the wood destroying the cellulose and sometimes the lignin as well. One the decay is thriving, it produces fruiting bodies (mushroom shaped usually) that produce thousands of spores and the cycle repeats. Masses of hyphae are called what? ------CORRECT ANSWER--------------- Mycelia Where is brown rot most frequently encountered? ------CORRECT ANSWER---------------In structures in California. What is another name for Brown Rot? ------CORRECT ANSWER-------------- -Dry Rot What does brown rot look like? ------CORRECT ANSWER---------------When dry, it appears especially dry. It causes the wood to become crumbly, even powdery. It cracks at intervals across the grain, and sometimes with the grain to form small chunks. What causes dry rot? ------CORRECT ANSWER---------------Excessive Moisture What are rhizomorphs? ------CORRECT ANSWER---------------In the water- conducting fungus "Poria", it's mycelia are intertwined into root-like strands called rhizomorphs. The rhizomorphs will branch and carry moisture from damp wood to relatively dry wood and allow the Poria to attack dryer wood than can be attacked by other fungi. Does the brown rot die when you remove the moisture? ------CORRECT ANSWER---------------No. Brown rot can survive for years in a wood that has become too dry. However, once moisture is returned to the wood, it will continue growth. This is why we must perform a rout and fill when correcting dry rot problems. We must rout out the rot to keep it from continuing to grow later. Brown rot attacks primarily... ------CORRECT ANSWER--------------- Softwoods White rot attacks primarily.... ------CORRECT ANSWER--------------- Hardwoods Which rot grows more slowly, brown rot or white rot? ------CORRECT ANSWER---------------White rot How does the wood appear when the white rot is in its later stages? ------ CORRECT ANSWER---------------It makes the wood spongy, "Stringy" Do molds cause structural damage? ------CORRECT ANSWER--------------- No. They do no significant structural damage, but do indicate the possibility of the presence of fungi decay. How do you remove mold? ------CORRECT ANSWER---------------By light brushing or shallow planing What family does The True Powderpost Beetle belong to? ------CORRECT ANSWER---------------Lyctidae What are the distinguishing features of the Larva of a True Powderpost Beetle (Lyctidae) Larva? ------CORRECT ANSWER---------------Larva C- shaped with six legs What are the distinguishing features of the Larva of a Deathwatch and Furniture Beetle (Anobiid) Larva? ------CORRECT ANSWER--------------- Larva white with black jaws and six legs Larva feeds on hard and soft wood When can an unlicensed person sign a pest control contract? ------ CORRECT ANSWER---------------Only after a licensed field rep or operator has previously negotiated the contract How many days do you have to file a termite report? ------CORRECT ANSWER---------------10 business days a report has to be filed. What type of life cycle or metamorphosis does a termite go through? ------ CORRECT ANSWER---------------Incomplete or gradual metamorphosis for a termite When should a pesticide applicator read a pesticide label? ------CORRECT ANSWER---------------Before each application How long does the board have to file a action against a company or a licensee after an act or omission concerning fraud is committed? ------ CORRECT ANSWER---------------2 years. In the case of Fraud, a complaint must be filed within 4 years. However the board then has 2 years to file an accusation. Death Watch Beetles are what type of Beelte? ------CORRECT ANSWER--- ------------Anobiid A written inspection and report of wood destroying pests and organisms shall be delivered in how many days from the date of inspection ------ CORRECT ANSWER---------------10 Business Days The address of each property inspected or upon which work is completed shall be reported and filed with The Board how many days after the commencement of inspection ------CORRECT ANSWER---------------10 Business Days It is unlawful for a registered company to solicit payment from the consumer for any structural fumigation work not actually rendered unless prior to the authorization the consumer is provided what notice? ------ CORRECT ANSWER---------------Notice: the charge for service that this company subcontracts to another registered company may include the company's charges for arranging and administering such service that are in addition to the direct costs associated with paying the subcontractor. You may accept (company's name) bid or you may contract directly with another registered company licensed to perform the work. In order for a registered company or licensee to commence work on a contract, or sign, issue, or deliver any documents expressing an opinion or statement relating to the absence or presence of wood destroying pests or organisms, what must first take place? ------CORRECT ANSWER------------- --An inspection has to have been made by a licensed Branch 3 Field Representative or Operator. What is the monetary disciplinary action for failure to report and file with The Board the address of any property inspected or where work completed pursuant to section 8518? ------CORRECT ANSWER---------------A fine of not more than $2,500. What is a reinspection ------CORRECT ANSWER---------------An inspection of those items previously listed on an original report to determine if the recommendation(s) has (have) been completed For how long is an original inspection valid? ------CORRECT ANSWER------ ---------Four months A registered company has how many days to perform an inspection after inspection is ordered? ------CORRECT ANSWER---------------10 business days What is a separated report? ------CORRECT ANSWER---------------A report in which the registered company separately identifies each recommendation for corrective measures for each section 1 item (infestation and/or infection that is evident) and for each Section 2 item (condition deemed likely to lead to infestation or infection) that is present. What is a Control Service when related to Wood Destroying Organisms ----- -CORRECT ANSWER---------------A regular reinspection of a property after a report has been made in compliance with section 8516. What are the conditions deemed likely to lead to infestation or infection ----- -CORRECT ANSWER---------------Earth-wood contacts, excessive moisture (including plumbing leaks), cellulose debris, faulty grade levels, evidence of roof leaks, and insufficient ventilation. When do you recommend to repair a stall shower? ------CORRECT ANSWER---------------If it is found to leak when water tested for a minimum of fifteen minutes after the shower drain has been plugged and the base filled to within one inch of the top of the shower dam. What is the minimum number of minutes that you must water test a stall shower with no dam? ------CORRECT ANSWER---------------5 minutes Are you required to water test a second floor stall shower? ------CORRECT ANSWER---------------No. However, if water stains are evident on the ceiling below the shower, the recommendation should be made for further inspection and testing. What is the recommendation for cellulose debris? ------CORRECT ANSWER---------------Remove. What Family of beetles do the roundheaded borers belong too? ------ CORRECT ANSWER---------------Cerambycidae What Family of beetles do the flatheaded borers belong too? ------ CORRECT ANSWER---------------Buprestidae What are the identifying features of a beetle in the Cerambycidae family? -- ----CORRECT ANSWER---------------These are the 'longhorn' beetles. Roundheaded Borer, New House Borer, Old House Borer, Flat oak borer, etc. Like the Bostrichid family of beetles, most only attack dying trees, logs, and unseasoned wood, except the Old House Borer and the Flat Oak Borer, which will attack buildings. Seasoned wood is often too dry. Most wood-boring beetles will be brought into the home in firewood. Trees killed by forest fire often become infected by beetles before the Timber companies can harvest them. The New House Borer is found in the western states and attacks softwoods (conifers) before the bark is removed. It will emerge later from wood once it has been used in a building. Killed by fumigation. Will not reinfest. The Old House Borer is found in the eastern states also only attacks softwoods (conifers), however it attacks seasoned softwoods in existing buildings. Will reinfest. The Flat Oak Borer is found only in the Eastern states attacks dry, seasoned oak and hickory in existing building. Will reinfest. Where does the female Roundheaded beetle (Cerambycidae) lay her eggs? ------CORRECT ANSWER---------------In the bark of the tree. The larvae then begin feeding extensively just under the bark and then bore deeper into the sapwood. What do the Roundheaded borer (Cerambycidae) larval galleries look like? ------CORRECT ANSWER---------------Frass packed inside and wind irregularly. What are the identifying features of a beetle in the Buprestidae family? ------ CORRECT ANSWER---------------Flatheaded - thorax of the larva is flattened from top to bottom causing 'flattened' or oval tunnels. Often called 'metallic wood borers' as most are a beautiful shiny metallic color. They attack soft and hardwood. But usually attack damaged or dying trees. They are HIGHLY attracted to burning material. Forest fires and industrial sites. They do not re-infest wood in buildings. Where does the female flatheaded beetle (Buprestidae) lay her eggs? ------ CORRECT ANSWER---------------In crevices in the tree bark or wood or at the edges of a tree wound. Larvae then bore into bark and then on into the wood. They do not eat only sapwood of the tree. What do the Flatheaded borer (Buprestidae) larval galleries look like? ------ CORRECT ANSWER---------------Flat galleries (4 or more times wider than high). Tightly packed with sawdust-like borings and pellets. Close examination shows each tunnel to be scared with fine, transverse lines. What are some identifying features of the Carpenter Ant? ------CORRECT ANSWER---------------Most are black, but some in Southern CA have orange thoraxes. How often shall a full inspection be completed for a property covered by a control service? ------CORRECT ANSWER---------------At least once every three years. What color is Golden Buprestid? ------CORRECT ANSWER--------------- Golden-green or Blue-green. Does an Ambrosia beetle damage wood in buildings? ------CORRECT ANSWER---------------No. They will not reinfest dead wood. If they are found in the home, they are merely escaping from the wood because of its dryness. How much water is needed for a stall shower test? ------CORRECT ANSWER---------------Fill within 1" of the top of the dam. What does the adult stage of the Carpenter Bee eat? ------CORRECT ANSWER---------------Pollen and nectar Chemical storage areas shall be posted with warning signs that are readable from? ------CORRECT ANSWER---------------From 25 feet. IPM programs consist of what four basic tasks? ------CORRECT ANSWER- --------------Inspection, eliminating conducive conditions, treatment, and monitoring Completion tags must be posted in what location? ------CORRECT ANSWER---------------Next to the inspection tag What size should the Inspection tags be? ------CORRECT ANSWER--------- ------3 x 5 card must contain: 1) the companies name 2) date of inspection 3) and the following statement. "Do Not Remove-Structural Pest Board Regulation 1996.1 What size should the Completions tags be? ------CORRECT ANSWER------ ---------3 x 5 card must contain: 1) the companies name 2) date of completion 3) and the following statement. "Do Not Remove-Structural Pest Board Regulation 1996.1 4) Name of any chemical used or any non-chemical methods of treatment made. How many days from their hiring date can an unlicensed individual legally apply pesticides and/or rodenticides as long as they are applied under the direct control of a field representative or an operator? ------CORRECT ANSWER---------------30 days legally apply pesticides and/or rodenticides Which is not a characteristic of a Carpenter Bee? ------CORRECT ANSWER---------------The Carpenter Bee social insect. Copies of reports must be kept for what length of time? ------CORRECT ANSWER---------------3 years is the length of time. Termite vs. Ant ------CORRECT ANSWER---------------Termite- straight antennae, straight waist, wings are same length Ant- bent antennae, pinched waist, wings are different sized Four Castes (Sub Termite) ------CORRECT ANSWER---------------1. Primary reproductive 2. Supplementary reproductive- young worker, soldier forming its big head or young primary forming wings. (all larger than primaries) 3. Worker 4. Soldier thousands Sub Size/ Appearance ------CORRECT ANSWER---------------workers and soldiers are a cream color 6mm primaries are dark chestnut to black with grayish wings They eat with the grain of the wood. Drywood Termites ------CORRECT ANSWER---------------Kalis (K)- usual control is fumigation with sulfuryl fluoride (vikane) (Pale yellow colored desert dry wood in southeast) Three Castes (Drywood Termite) ------CORRECT ANSWER--------------- Primary Reproductives Unlike the galleries of dry woods, sub termite galleries contain a great deal of mastic material ------CORRECT ANSWER---------------True Sub termite primary reproductives are about 1/3 to 1/2 " long ------ CORRECT ANSWER---------------True Sub termites typically eat across the grain of the wood ------CORRECT ANSWER---------------False- With the grain the wings of the primary reproductives are translucent and grayish when viewed on white paper ------CORRECT ANSWER---------------True If there are small parts of the building where the moisture and humidity might be extraordinarily great, there is the possibility that the subterranean termites are not returning to the soil at all. ------CORRECT ANSWER--------- ------True Drywood termites are also known as Kali's ------CORRECT ANSWER-------- -------True Heating the building for several hours is another method being used in termite control ------CORRECT ANSWER---------------True Methyl Bromide fumigation is the usual method of controlling drywood termites ------CORRECT ANSWER---------------False- Sulfuryl fluoride (Vikane) Rain stimulates drywood termite swarms ------CORRECT ANSWER---------- -----False Drywoods pellets has how many concave sides? ------CORRECT ANSWER---------------6 Drywood termites have two stout veins at the wings ------CORRECT ANSWER---------------False- three Drywood termites are larger than the subs but smaller than damp woods --- ---CORRECT ANSWER---------------True the third segment of the western dry wood termite soldier antenna is extra large ------CORRECT ANSWER---------------True The pacific coast damp wood termite is one of our most primitive termites. it has no worker caste and it is the largest species in the US. ------CORRECT ANSWER---------------True Dampwoods swarm throughout the year, but most often from july through october, just before sunset ------CORRECT ANSWER---------------True Dampwood termites must have periodic contact with the soil to survive ------ CORRECT ANSWER---------------False Dampwood gallery surfaces sometimes have a velvety appearance ------ CORRECT ANSWER---------------True The damp wood termites get rid of their pellets by kicking them out of holes through the wood ------CORRECT ANSWER---------------False Dampwood termite wings have a brownish leather like appearance ------ CORRECT ANSWER---------------True The Formosan termite is a subterranean species and must have contact with the ground in order to survive ------CORRECT ANSWER--------------- False powder post beetles, roundheaded and flat headed borders, bark and ambrosia beetles, and wood weevils are all types of wood boring beetles that require control in buildings ------CORRECT ANSWER---------------False The exit holes of powder post beetles are easily mistaken for the exit holes of round headed borers ------CORRECT ANSWER---------------False The kick holes of the dry wood termite can be mistaken for the exit holes of one of the three types of powder post beetles ------CORRECT ANSWER---- -----------True Anobiids tend to attack newer wood than lyctids ------CORRECT ANSWER- --------------False Like the Lyctid, the Anobiids lay their eggs in the pores of wood ------ CORRECT ANSWER---------------False- cracks and crevices The Anobiids have relatively long life cycle. Two or three years may be required for just the larval stage ------CORRECT ANSWER---------------True Most Anobiids attack both hardwoods and softwoods ------CORRECT ANSWER---------------True It usually is possible to detect an Anobiid infestation by the presence of holes bored by the female in which she lays her eggs ------CORRECT ANSWER---------------False Anobiid frass is tightly packed in the tunnels, or at least loosely packed ----- -CORRECT ANSWER---------------True Bostrichids (False Powder Post Beetles) Rarely reinfest wood in a building; and they are not considered serious pests of buildings ------CORRECT ANSWER---------------True Bostrichids are found in both hardwoods and softwoods ------CORRECT ANSWER---------------True The egg-laying of the Bostrichids is different from that of other wood boring beetles, forming egg tunnels into which the females lay their eggs ------ CORRECT ANSWER---------------True It is normally unnecessary to control Bostrichid beetles in buildings. ------ CORRECT ANSWER---------------True The last 3 or 4 segments of the Bostrichids antennae are enlarged to form a distinct club. ------CORRECT ANSWER---------------True Round Headed Borers ------CORRECT ANSWER---------------Family Cerambycidae- or the longhorn beetles are called this because of their long antennae. except for the old house borer and the flat oak borer found in the east. they attack dying trees, logs, and unseasoned lumber. New House Borer ------CORRECT ANSWER--------------- ArhopalusProductus attacks only conifers (Softwoods) and does so before the bark is removed. it often emerges from Douglas fir sublooring. It does not reinfest, but fumigation is the only way to get rid of it. Old House Borer ------CORRECT ANSWER---------------Reinfests wood in buildings in the eastern states only. only attacks softwoods and its prime target is seasoned coniferous wood in existing buildings. rarely ever does it attack stumps and logs flat oak borer ------CORRECT ANSWER---------------is the only other borer that reinfests wood that is seasoned and dry. it attacks oak and hickory, but only occurs in the eastern states as well. Borers life cycle ------CORRECT ANSWER---------------under the bark at first and then bore deeper into the sapwood. The larva period is very long- a few months to several years. longer if the wood is dry and cut into dimension lumber. Borer Damage ------CORRECT ANSWER---------------exit holes are large and round. Also depending on the type of borer, will the size differentiate. Flatheaded borers ------CORRECT ANSWER---------------most are a beautiful shiny metallic color, ofter called "metallic wood borers". the name flat headed comes from the fact that the thorax of the larva is enlarged like a roundheaded borer. They do not reinfest the wood in buildings and are attracted to fire and smoke. Golden Buprestid ------CORRECT ANSWER---------------Wester states species that attracts much more attention when it emerges in a residence. even though it is of little economic importance and requires no treatment. Golden Buprestid Biology ------CORRECT ANSWER---------------Eggs are laid in crevices in the tree bark or wood. the trees are usually injured or dying. the young larvae bore ion the bark, then on into the wood. they are known for their long life cycles of 2-4 years in larvae stage. they are also known to emerge 26-50 years after the initial infestation. At what moisture Level % does the Ambrosia beetle leave the wood? ------ CORRECT ANSWER---------------below 30%- Not seen in buildings Entry and Exit Hole Size: Ambrosia Beetles ------CORRECT ANSWER------- --------they are all the same size because only the adults enter and exit the wood. How to control wood boring beetles ------CORRECT ANSWER---------------1. physical evidence of actual damage- Frass 2. specimens of the pest doing the damage The fact that frass and damage is present does not mean anything unless the beetles are still present. Section 8516 Evidence Report ------CORRECT ANSWER---------------if the customer asks for a separate report the company is required to give them one that shows bot the actual evidence of an infestation along with conditions that exist that could lead to an infestation When is control of wood boring beetles necessary? ------CORRECT ANSWER---------------when there is an active infestation and the species of beetle is one that will re-infest seasoned wood Lyctid and Anobiid Powder post beetles in California Best way to control Beetle infestation ------CORRECT ANSWER--------------- Replace the wood with NEW dry wood Remove dampness and decay Vikane ------CORRECT ANSWER---------------Sulfuryl fluoride Not always the best for treating beetle larvae Methyl bromide @ 3 pounds per 1000 cubic ft Does drill and treat work well for wood boring beetles? ------CORRECT ANSWER---------------No it is easier to detect the presence of wood boring belts than termites ------ CORRECT ANSWER---------------False the two kinds of beetles most likely to require fumigation are bostrichid beetles and lyctid beetles ------CORRECT ANSWER---------------False- Anobiid and Lyctid Lyctids are the only wood boring beetle to attack wood with a moisture content of less than 15% ------CORRECT ANSWER---------------True Carpenter Ants ------CORRECT ANSWER---------------swarm during early spring and summer, they prefer soft moist wood with decay, the queen nourishes her young using the nutrient from her no longer needed wing muscles. The workers can not sting, but can inflict painful bites usually the colony remains in a stump or a log and travels back and forth to the wood source Frass is similar to saw dust in piles or scattered They prefer the soft spring wood and will cut tunnels in the summer wood to gain access to the spring wood. Galleries of Carpenter ants ------CORRECT ANSWER---------------Are clean and completely removed of Frass they look much like dry wood termite galleries, just without the fecal pellets and kick holes Treatment for Carpenter Ants ------CORRECT ANSWER---------------Finding the nest and treating the nest Not finding the nest but eliminating the problem by spraying and injecting walls floor and door frame and sills and any other void near the property Removal of any and all wood debris Dri-Die 67 Drione Carpenter ants eat wood ------CORRECT ANSWER---------------False within 2-3 years the colony consists of a few thousand including male and female reproductives ------CORRECT ANSWER---------------True Rhizomorphs ------CORRECT ANSWER---------------Transport moisture for water conducting fungi brown rot will die soon after the woods water content drops below 20% ----- -CORRECT ANSWER---------------False Sap Stain fungi such as blue stain can sometimes penetrate the wood and cannot be removed ------CORRECT ANSWER---------------True submerging wood in water speeds up wood decay ------CORRECT ANSWER---------------False most wood decay begins on end cuts of wood ------CORRECT ANSWER--- ------------True 2 types of field treated wood products ------CORRECT ANSWER-------------- -Copper Napthanate Zinc Napthanate Molds ------CORRECT ANSWER---------------largely superficial and usually can be removed by brushing or shallow planning. they do no damage structurally Sap Stain ------CORRECT ANSWER---------------does not do damage but can foretell the presence of decay fungi Soft Rot ------CORRECT ANSWER---------------is a slow processed brown rot that can be easily removed by scraping the surface of the wood Three essentials for decay fungi in wood ------CORRECT ANSWER---------- -----Oxygen, Temperature, moisture White Rot ------CORRECT ANSWER---------------attacks hardwoods and takes on a more bleached color than before the attack it is slower than brown rot, but over time it will make the wood spongy. This will leave small white pockets in the wood Brown Rot (Poria) ------CORRECT ANSWER---------------soft wood attacking, making the wood turn into slivers that are easily torn apart. the water conducting fungus uses its mycelia that are a root like organism called Rhizomorphs. These Rhizomorphs carry moisture into the wood so they fungus can attack further into the wood. Mycelia ------CORRECT ANSWER---------------Masses of tiny germinating spores that are microscopic growing strands called hyphae Hyphae ------CORRECT ANSWER---------------are the tiny spores that make up Mycelia. They grow across the woods cell walls destroying the cellulose and in some species the lignin as well.
