OUR APPROACH
How We Eliminate Cockroaches
Identify the Species
German and Oriental cockroaches live differently — German cockroaches breed continuously indoors near warmth and moisture, Oriental cockroaches prefer cool damp areas and drains. Placement changes completely depending on which you have.
Bait the Harbourage
Gel bait and a growth regulator are placed at harbourage points — behind and under kitchen equipment, in motor housings, inside wall voids near plumbing — rather than sprayed across open surfaces they avoid.
Return for the Hatch
A follow-up visit is part of the job, not an upsell. Egg cases are resistant to treatment, so the nymphs that hatch after the first application have to be caught by the second.
How to Identify Cockroaches
German cockroaches, the most common indoor species in Ontario, are light brown with two dark stripes behind the head and rarely grow past 16mm. Droppings resembling coffee grounds or black pepper, a musty odour, and shed skins near warm, humid areas like kitchens and bathrooms are the clearest signs.
Seasonal Behaviour in Ontario
Cockroaches breed continuously indoors regardless of season since they depend on the stable warmth and moisture of a structure rather than outdoor temperatures. A female can produce dozens of offspring from a single egg case, which is why visible activity often means a population is already well established.
DIY or Call a Professional?
A single cockroach, especially near a door or drain, doesn't necessarily indicate an infestation. Sightings during the day — roaches are nocturnal and avoid light when possible — multiple sightings, or finding droppings and egg cases mean the population has outgrown what store-bought bait can manage; gel baits and residual treatment in harborage areas typically require professional application to reach every life stage.

COMMON QUESTIONS
Cockroach Control — Questions We Get
Why do cockroaches need a follow-up visit?
Because egg cases survive the first treatment. A German cockroach ootheca protects the eggs inside from most applications, so nymphs hatch days to weeks later into a treated environment. The follow-up is timed to catch that hatch. Skipping it is the most common reason a treatment appears to fail.
Does treating one unit work in an apartment building?
Rarely on its own. Cockroaches travel between units through shared wall voids, plumbing chases and service risers, so an untreated neighbouring unit re-seeds the treated one. For multi-unit buildings we recommend treating the adjoining units and shared structure together, and can coordinate with a property manager.
