How to Know You Have Cockroaches

Early detection is the key to fast, cost-effective elimination. Here's what to look for:

  • Sightings during the day — indicates severe overcrowding in the population
  • Musty, oily odour in kitchen or bathroom areas
  • Small dark droppings resembling ground pepper or coffee grounds
  • Egg cases (oothecae) — brown, ridged capsules under appliances or furniture
  • Smear marks — dark streaks along walls in areas of high humidity

Species Found in Ontario Homes

German Cockroach (Blattella germanica)

Ontario's most problematic species. Small (1.5cm), tan with two dark stripes. Prefer warm, humid kitchen and bathroom environments. Reproduce extremely rapidly.

American Cockroach (Periplaneta americana)

Ontario's largest cockroach species (4cm+). Reddish-brown. Often found in basements, drains, and commercial kitchens. Can fly short distances.

Oriental Cockroach (Blatta orientalis)

Dark brown to black, slow-moving. Common in damp basements, drains, and utility areas. Can tolerate cooler temperatures than other species.

Brown-Banded Cockroach (Supella longipalpa)

Smaller cockroach that hides in higher, drier locations — bookshelves, electronics, picture frames. Often overlooked in treatments targeting lower areas only.

How We Eliminate Cockroaches

A science-based, 4-step approach that treats the root cause — not just the symptoms.

1

Full Inspection

We inspect all harborage sites: behind and under appliances, inside cabinets, wall voids near plumbing, and any areas with warmth and moisture. We identify the species and severity.

2

Targeted Gel Bait + IGR

We apply professional-grade gel bait in precise harborage locations, combined with Insect Growth Regulator (IGR) to disrupt reproduction. This combination eliminates both existing roaches and prevents new hatchlings from maturing.

3

Void Treatments + Crack & Crevice

Residual spray or dust in wall voids, under cabinets, and along utility runs where roaches travel between harborage sites.

4

Follow-Up Inspection

We return 2–3 weeks after initial treatment to assess efficacy, re-bait if necessary, and confirm the population is collapsing. We don't close the ticket until the infestation is resolved.

Cockroaches Control — FAQ

I only saw one cockroach — do I need professional treatment?

Almost certainly yes. Cockroaches are nocturnal and hide when populations are low. Seeing one during the day typically means the hidden population is already large. They reproduce extremely fast — waiting makes the problem significantly harder and more expensive to resolve.

How long does cockroach treatment take to work?

Gel bait starts working within 24–48 hours. You'll typically see a significant reduction in visible cockroach activity within 1–2 weeks. A follow-up visit 2–3 weeks after initial treatment confirms full resolution.

Are cockroach treatments safe for food prep areas?

Yes. We use gel bait formulations approved for food-handling environments and apply them in precise harborage locations away from food preparation surfaces. We follow all Health Canada guidelines for food-contact zone treatments.

Why won't store-bought sprays work?

German cockroaches have developed widespread resistance to the pyrethroid class of insecticides found in most consumer sprays. Additionally, sprays scatter roaches without eliminating harborage sites — spreading the infestation. Professional bait and IGR formulations are far more effective.

Can cockroaches spread through an apartment building?

Yes — they travel through wall voids, plumbing runs, and shared spaces. We recommend informing your property manager and inspecting adjacent units if you're in a multi-unit building.

How do I prevent cockroaches from coming back?

Fix leaks (cockroaches need water), seal gaps around plumbing, keep food in sealed containers, and avoid cardboard clutter (a favourite harborage material). Our follow-up visit includes a prevention assessment specific to your property.
