Why do I have cockroaches?

Cockroaches need food, moisture and warm hiding spots. Crumbs, dishes left out, a leak under the sink, cracks behind cabinets, warm appliances — all of it attracts them. In multi-unit buildings, they also travel from neighbouring units through walls, pipes and ducts.

Even if you only see a few, a hidden infestation may already be established. The ones you see are a small fraction of the colony — and they reproduce extremely fast.

How our treatment works

Professional gel baits exploit cockroach behaviour itself: workers carry the product back to the colony and contaminate each other. That's how we reach the insects that store-bought sprays never touch.

Full inspection to locate infested zones and travel routes (plumbing, cracks, appliances).
Professional gels applied directly in hiding spots: behind cabinets, under appliances, in crevices.
Treatment of cracks and risk zones throughout the kitchen and bathroom.
Follow-up visit included, written 6-month guarantee.

No heavy preparation needed and your home stays livable: gels are applied in targeted spots, out of reach of children and pets.

Preventing their return

Clean crumbs and kitchen surfaces regularly; keep garbage bins closed.
Fix water leaks under the sink — without water, colonies decline.
Don't leave food out; store dry goods in airtight containers.
Seal cracks in walls and around cabinets.
Important: store-bought foggers make things worse by scattering the colony deeper into walls.

FAQ — Frequently asked questions

Is it dangerous to live with cockroaches?

Yes. They contaminate food and prep surfaces, can carry bacteria, and worsen allergies and asthma — especially in children. The longer an infestation lasts, the higher the health risk.

How long until they're gone?

Most infestations are under control within one to three weeks depending on severity. Our 6-month second-visit guarantee applies: if the problem persists, we come back free of charge.

Who pays in a rental unit — tenant or landlord?

In Quebec, the landlord must keep the dwelling fit for habitation, which includes being vermin-free. Notify your landlord in writing right away; in multi-unit buildings, adjacent units should be treated at the same time.
