At what temperature do bed bugs die, according to Health Canada?
- -5°C
- 40°C
- 50°C
- 30°C
Why should dead ants be left in place after a carpenter ant treatment?
- They show the client the treatment worked
- They act as bait for spiders and centipedes
- Other ants may carry the pesticide back to the nest
- They warn other ants that they should leave the building
How do carpenter ants damage wood?
- They eat the wood like termites do
- They tunnel to nest but do not eat it
- They only nest in new, dry lumber
- They dissolve it with acid sprays
What gives lasting control of carpenter ants?
- Spraying the trail of foraging ants on the kitchen counter
- Vacuuming up every ant seen on the floors each evening
- Finding and treating the nest, including the parent colony
- Placing sticky traps under the sink for several weeks
Which type of registered product is most commonly used for cockroach control?
- Residual crack-and-crevice treatments
- Lawn granules spread around the house
- Herbicide sprays applied to baseboards
- Fumigant gases released in the kitchen
Where are flea eggs, larvae and pupae mostly found?
- In and around pet sleeping areas
- On kitchen counters
- On the pet's skin only
- Inside wall cavities and behind the baseboards
A product is labelled for bed frames. May it be applied to the mattress?
- No, only where the label allows
- Yes, at half the label rate
- Yes, mattresses are part of the bed
- Yes, if the mattress is covered
How can you recognize a German cockroach?
- Shiny black, about 5 cm long, with no wings at all
- Reddish with a white band across the middle of the back

- Tan to light brown with two dark stripes behind the head
How can you tell a carpenter ant from a termite?
- Carpenter ants have straight antennae and a thick waist
- Carpenter ants have elbowed antennae and a thin waist

When is the best time to treat an active wasp nest?
- Any time, as long as you move quickly
- Early afternoon, when workers are out foraging
- After nightfall, when wasps are least active
- At noon on a hot day, when the nest is empty
What is the main purpose of sticky traps in a cockroach program?
- To eliminate a large infestation without other steps
- To attract roaches from neighbouring units for removal
- To replace sanitation in restaurants and kitchens
- To show where roaches are so treatment can be focused
Which statement about bed bugs is correct?
- They cannot fly or jump
- They mainly feed during the day
- They are known to spread disease
- They die within a week without food
What condition often attracts carpenter ants into a building?
- Dry, new lumber
- Freshly painted walls
- Bright exterior lights
- Moist or decaying wood
What does Health Canada say about using pesticides alone against cockroaches?
- They work best when sprayed every single day
- They are enough on their own, without cleaning
- They work best combined with intensive cleaning
- They work only if the room is kept very warm
When are cockroaches most active?
- At dawn only
- In bright light
- At night
- At midday

Integrated approach
- Combine sanitation, exclusion and monitoring with pesticides; pesticides alone rarely give lasting control.
- Identify the pest first, since the right control depends on the species.
- Always use registered products labelled for the pest and site, and follow every direction.
Cockroaches (2024-03-13)
- The German cockroach, the most common household species, is about 1.3–1.6 cm long, tan to light brown with two dark parallel stripes behind the head; it has wings but does not fly.
- Cockroaches seek warm, damp places with food and water, are mostly active at night and come in with furniture, cartons, bottles and egg cases.
- They contaminate food and can trigger asthma; their presence does not always mean poor sanitation.
- Control: clean spills, store food sealed, remove garbage daily, fix leaks, seal cracks and use sticky traps for monitoring.
- Residual crack-and-crevice products are the most common registered treatment; baits kill about 48 to 96 hours after feeding.
Carpenter ants (2013-06-04)
- Carpenter ants are 6–25 mm, black or red-and-black, with elbowed antennae and a slim waist; termites have straight antennae and a thick waist.
- They do not eat wood: they excavate galleries and push out sawdust-like frass; they prefer moist, decaying wood.
- Signs: frass piles, slit openings in wood, foraging trails and rustling at night; satellite colonies are common.
- Lasting control requires finding and treating the nest (or the parent colony), plus fixing moisture and removing infested wood.
- Leave dead ants after treatment so others carry the pesticide back to the colony.
Bed bugs (2015, 2022)
- Adults are up to 10 mm, oval, flat and brown (red after feeding); they cannot fly or jump.
- They feed on blood mainly at night, attracted by carbon dioxide, and can survive weeks to 1.5 years without feeding.
- They are not known to spread disease; bites can take up to 14 days to appear.
- Bed bugs die at 50°C; steam, hot washing and drying for 30 minutes or more help; freezing needs 4 days at -19°C and may not work.
- Do not apply products to people, pets or bedding unless the label allows; bed-frame products are not for mattresses.
Fleas (2020) and Wasps (2017)
- Fleas: 1–4 mm, wingless; eggs, larvae and pupae live in pet resting areas; treat pets (with a vet's advice), vacuum daily and treat the home.
- Wasps: yellowjackets and hornets are 10–25 mm and can sting repeatedly; treat nests after nightfall when wasps are least active, wear protective clothing including a head net, and use a red-filtered light.
