Pest control: key rules to remember
Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗
Introduction and cockroaches
- Pests contaminate food, damage buildings (electrical/fire hazards, holes); greatest threat is spreading disease.
- Cockroaches live up to two years; a female can lay over 500 eggs; eggs protected by an egg case.
- Hide where it is dark, warm, moist and hard to clean: behind fridges/stoves, drains, around hot water pipes, motors, under shelf liner/wallpaper, in delivery boxes and bags.
- Strong oily odour; droppings look like large grains of pepper; lay eggs in corrugated cardboard.
- Seeing cockroaches in a lit area usually means a serious infestation.
Common types in Ontario
- German: pale brown/tan, 10–15 mm; motors, cracks, drink machines; reproduces fastest. Oriental: shiny black, 25–32 mm; basements, pipes. American: reddish brown, 34–53 mm; drains, sewers. Brown-banded: like German; dry storage, under tables. Asian: like German but flies; drawn to light.
Flies and other insects
- Flies breed in garbage and feces; a housefly lays 375–750 eggs; eggs hatch in as little as seven days.
- Hairy bodies and suction-cup feet carry contaminants; they vomit on solid food to dissolve it and defecate while feeding.
- Can enter through a pin-head opening.
- Flour moths and beetles in dry storage: look for insect bodies, wings/webs, clumped food, holes in packaging. Ants nest near stoves and hot water pipes; like greasy and sweet food.
Rodents
- Damage buildings, chew wires (fire risk); spread disease through urine and feces as they move.
- Rats avoid poorly set traps; rat bites dangerous; handle dead rats carefully.
- Active at night; seeing them in daylight = heavy infestation.
Integrated pest management
- Prevention is easier and cheaper than getting rid of pests.
- IPM: deny food, water and shelter (sanitation); pest-proof the building; work with a licensed pest control company (for prevention too). Minimize reliance on chemicals.
- Before spraying, cover food and dishes; after, clean and sanitize all food contact surfaces; never spray during food preparation. Traps, glue boards, baits; follow-up.
Pest proofing and housekeeping
- Seal gaps and cracks; fix leaky plumbing; screens on windows, doors, vents; plastic strips or air curtains on receiving doors.
- Don't leave doors open; door sweeps — mice fit through a quarter-inch (about 6 mm) gap, rats through a half-inch.
- Store food 15 cm off the floor; grains in sealed metal or heavy plastic containers; keep break rooms clean and dry.
- Don't accept shipments with pest signs; don't keep cardboard (cockroach eggs); clean spills right away; store garbage properly.
Pest control
- Premises protected against entry of pests and kept free of conditions that lead to harbouring or breeding.
- Operator keeps records of all pest control measures for at least one year (Toronto Public Health: records on site for the last 12 months).

- Receiving and storageInspecting deliveries: temperatures, cans, packaging, meat, fish, shellfish, eggs, dairy, MAP and dry goods; rejecting a shipment; storing food off the floor, away from chemicals and in food-grade containers; FIFO stock rotation.
- Cooking, cooling and reheatingMinimum internal cooking temperatures for poultry, ground meat, pork, fish and food mixtures; the two-stage cooling rule (60 °C to 20 °C in 2 hours, then to 4 °C in 4 more); shallow pans and ice baths; reheating quickly to a safe temperature.
