How can you tell the difference between wood suffering from brown rot and wood suffering from white rot? - correct answer- Wood infested with brown rot typically:
Do subterranean termites live entirely within wood? Why or why not? - correct answer- No, because they require a constant source of moisture to survive. However, they can live in wood with less than 20% moisture by getting their moisture from the ground. They transport this moisture through flattened, earthen shelter tubes that serve as passageways from the soil to the infested wood. How do subterranean termites most often infest wood in buildings? - correct answer- They gain entry through untreated wood that touches or is close to the ground, particularly at porches, steps, and terraces. They can also infest buildings through cracks or voids in foundations or concrete floors that make it easy for termites to reach wood that is not close to the soil. Describe the frass pellets of drywood termites. - correct answer- They are small and cylindrical with six depressions on the sides. These pellets are unique to drywood termites and are used for identification. Where do drywood termites most often occur? - correct answer- In southern Florida, southern California, and along the southern gulf coast of the United States.
Do drywood termites live entirely within wood? Why or why not?
Old house borers - seasoned wood; softwoods such as pine, spruce, and fir. Flatheaded borers - living trees as well as recently felled and dead standing softwood trees; rustic structures and some manufactured products. How do powderpost beetles get their name? - correct answer- In the tunnels that they bore, powderpost beetle larvae leave undigested wood particles called "frass." Frass usually appears as a fine wood dust or powder. When you cut or break infested wood, the interior reveals galleries filled with frass. Slight jarring of the wood often causes a fine powder to sift from the holes. These are all sure signs of a powderpost beetle infestation. Which type of powderpost beetle prefers hardwoods? - correct answer- Lyctids. Describe the differences in the frass produced by the three different groups of powderpost beetles described in this manual.
Anobiids - coarse and powdery frass; also contains distinctive fecal pellets shaped like hotdog buns. Bostrichids - grainy or mealy frass tightly packed in galleries. The adult of which type of powderpost beetle has a humpbacked appearance? - correct answer- Bostrichids. Describe the appearance of an adult old house borer. - correct answer- Adults are about 3/4 inch long and grayish brown to black. They have two white patches on the wing covers. Do wood-boring beetles structurally damage the wood that they infest? - correct answer- One generation of beetle damage does not usually weaken wood. But, boring of generation after generation can reduce the strength and integrity of wood. What are exit holes? Why are they important to pest managers?
answer- Carpenter ant galleries do not follow the grain and occur in the softer portions of the wood. Carpenter ants keep their galleries smooth and clean. You will not find mud in the galleries as you do with subterranean termites. Nor will carpenter ant galleries contain any powdery dust or pellets like wood-borer frass. Do all wood preservatives protect wood from carpenter ants and carpenter bees? - correct answer- Unfortunately, some preservatives may not completely protect wood against damage from carpenter ants or carpenter bees. Suppliers of wood treated with these chemicals may exclude carpenter ant and carpenter bee damage from warranties that they offer. How can you distinguish a carpenter bee from a bumblebee? - correct answer- Carpenter bees have shiny, black, hairless abdomens, whereas the abdomen of a bumblebee is yellow and hairy. Bumblebees also have large pollen baskets on their hind legs. These baskets are absent on carpenter bee legs. Describe the types of wood carpenter bees most often attack. - correct answer- Carpenter bees bore into seasoned woods, especially softwoods such as cedar, redwood, pine, and fir. Bees may damage soft or weathered wood on porches, decks, shed ceilings, railings, overhead trim, porch furniture, dead tree limbs, fence posts, wooden shingles, wood siding, windowsills, and wood doors. They prefer unpainted surfaces but will attack
painted wood as well. In most cases, carpenter bees will seek out the wood from which they developed as larvae. How can you distinguish a carpenter bee bore hole from the exit hole of an old house borer? - correct answer- The diameter of a carpenter bee hole is typically larger, about 1/ inch compared to 1/4 to 3/8 inch holes of old house borers. Also, carpenter bees create bore holes that are perfectly round. Old house borers create irregular (often oval) exit holes. Gradual Metamorphosis - correct answer- Insects that develop without much visible change between their immature instars to the adult. Just an increase in size. (SILVERFISH) Incomplete Metamorphosis - correct answer- insects that undergo change from egg through several instars to a final winged adult stage. ( DRAGONFLIES) Complete Metamorphosis - correct answer- insects include the egg, leveral larval instars, a pupa stage and winged adult. These appearance of these insects changes drastically. (BUTTERFLIES, BEETLES, FLEAS, ANTS, FLIES, AND WASPS,
Carpenter Ants - correct answer- Do not eat the wood they just chew it out wet/ rotten wood to make a nest area. Largest ants in GA Wood Boring Beetles ( 4 different families of beetles) - correct answer- 1) True Powder post beetles 2) Deathwatch beetles 3) False powderpost beetles and 4) Old House Borers True Powderpost beetles feed on - correct answer- hardwood lumber and usually dont re-infest finished wood Deathwatch Beetle feeds on - correct answer- softwood and hardwood and pine commonly re-infest any softwood False Powderpost beetles feed on - correct answer- variety of wood and plant materials like dried vines or flower stems Old House Borers - correct answer- prefers softwoods and the largest of the wood destroying beetles that re-infest structural wood
Wood Decay Fungi - correct answer- diverse group of organisms that are different than plants and animals that live in the soil, water, and air Wood Decay Fungi feed on - correct answer- the structural components of wood and require moisture to be able to infest and digest lumber. Fungi produces spores. Wood Decay Fungus does what - correct answer- fungus rots the wood, NOT the water Brown Rot fungi does what - correct answer- digest the hemicellulose and cellulose which causes the wood to shrink and turn BROWN White Rot fungi does what - correct answer- digest the lignin and cellulose and leaves the wood WHITE inspection tag - correct answer- 3x posted in attic, garage or subarea for ALL wdo inspections
recommendation to fumigate - correct answer- should ALWAYS be made when DRYWOODS are found leading to inaccessible areas or are widespread whenever pellets or frass is found - correct answer- always recommend TREATMENT AND REMOVAL, MASKING or COVERING of pellets standard shower test - correct answer- cover the flow of water to a 2 inch depth for 15 minutes INSPECTION or COMPLETION - correct answer- MUST be filed with the board WITHIN 10 DAYS!! FILING FEE - correct answer- $1.50 per address failure to file - correct answer- could result in disciplinary action AND fine up to $ all REPORTS and WORKSHEETS - correct answer- MUST be kept for 3 years
if SPCB requests report - correct answer- you have 2 days to submit! after 4 months from original inspections - correct answer- ALL re-inspections shall be ORIGINAL RE-INSPECTION CHARGE - correct answer- cannot be more than the original inspection notice of work completed and not completed - correct answer- shall be given to owner or owner's agent within 10 WORKING DAYS after completing work under the contract. (form is prescribed by board) 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
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. If structural pest control work is to be done on a property the owner, owners agent, and tenant must be given written notice of what per section 8538(a)? - correct answer- 1. Pest to be controlled
