Usually all you need is a vacuum to remove box elder bugs from a home. No pesticides required.
True. Vacuuming box elder bugs is effective.
Old bird nests and rodent carcasses can attract carpet beetles.
True
Pesticides are the key to controlling cockroaches.
False. Sanitation is key! Fix the environmental conditions first and pesticides come next.
Cockroaches undergo “incomplete metamorphosis”
True. Life cycle is egg –> nymph –> adult
Cockroach eggs usually hatch in 1 week
False. It’s generally about 2 months to hatch
The most common cockroaches found in Utah are German, Oriental, Brown-Banded, and American
True. Memorize these! German, Oriental, Brown-Banded, American.
There are three known poisonous spiders in Utah: The Black Widow, Desert Recluse, and Hobo
False. There are only two: Black Widow and Desert Recluse. Hobo spiders are not present in Utah.
A house mouse weighs about 10 ounces.
False. They weigh 1 ounce maximum.
A house mouse has a pointed snout.
True. They have large ears and a pointy nose.
Termites are attracted to moist areas where wood touches the soil.
True. To prevent termites, your wood foundation should not touch the soil.
If spraying an ant colony directly, always use a low pressure spray.
ASk chris? I didn’t know if the answer was low pressure or high pressure.
Rodents are more likely to be bait shy if you’re using a long-acting rodenticide.
False. Long-acting rodenticide lets the rodents eat several doses before killing them, making it more likely they will all join in and eat it. Single dose rodenticide kills rats quickly and makes other rats scared to eat it.
Trapping is the best defense for a large rodent population.
False. Trapping is effective with SMALL rodent populations. Large populations usually require rodenticide baiting.
Chemical sprays are the best way to control flies.
False. Sanitation is key. Remove breeding grounds and food sources. Electric traps are also effective. A spray will provide quick knock down of adults but they will continue to breed as long as there is poor sanitation.
Keeping grass, wood and other natural material at least 1 ft away from your foundation will help prevent crickets from entering your home
True.
Moths undergo complete metamorphosis
True. Egg –> Larva –> Pupa –> Adult
Baseboard sprays, fogging and broad applications are effective for killing moths.
False. These are a waste of time. Find the source of moths and eliminate it. Wash clothing in hot water, throw away contaminated food, empty cabinets and wipe them down, etc.
Indian meal moths are most common in temporary storage facilities.
False. Large amounts of food that has been stored past it’s expiration date is most likely source for indian meal moths.
Finding and treating a carpenter ant nest is the key to success
True. Liquid or granular pesticides on an OUTDOOR nest is the fastest way to kill ants. A dust or wall injection is best if the nest is INDOORS.
Simple metamorphosis consists of: Egg –> Nymph –> Adult
True. Memorize this.
Simple metamorphosis is also called “incomplete metamorphosis”
True.
Complex metamorphosis is also called “incomplete metamorphosis”
False. Complex metamorphosis is also called “complete metamorphosis”
Complete metamorphosis consists of: Egg –> Larva –> Pupa –> Adult
True
Bed bugs feed off dust from human skin cells.
False. Bed bugs feed off blood.
Ants usually invade structures to find food.
True. Shelter and warmth are not as important as food.
Carpenter ant inspections should always start with the rafters because that’s the most common place for nests.
False. Carpenter ants travel up wood that is touching the soil. Start with the foundation and look for wood contacting soil.
Cold and dusty glue boards are less effective for catching rats and mice.
True. Glue isn’t as sticky when it’s really cold or dusty.
When controlling a structural pest, it’s key to treat areas where human food is stored.
False. Do not treat human food with pesticides! Treat areas where pests visit and inhabit.
Spilling pesticides on soil full of clay and organic matter is at high risk of groundwater contamination.
False. High clay content and lots of organic material will help slow contamination.
A site with sandy soil and a shallow aquifer is at high risk of groundwater contamination.
True. Pesticides move through sandy soils easily. Shallow aquifers are close to the surface and pesticide reaches them easily.
Best practice for treating beetles is fumigating monthly.
False. A perimeter spray with insecticide is best.
Elm leaf beetles cause damage to leaves by “skeletonizing”
True. The larva eat through the leaf surface leaving a “skeleton” of leaf veins behind.
To protect kids and pets from rodent bait it should only be used in a locked room.
False. Place bait in a bait station that restricts access by kids and pets.
“Carbaryl” is an example of a common name.
True. The common name “carbaryl” is an accepted short hand for the chemical name “1- naphthyl methylcarbamate”
A product’s trade name and common name can be different.
True. A trade name is the name used to buy and sell and particular brand of product. The common name is a shorthand for the active ingredient. The chemical name is the technical name for the active ingredient. If I bought a bottle of water: Aquafina is the trade name. Water is the common name. H2O is the chemical name.
