The Problem
The Cockroach Problem
Cockroaches are one of the most unpleasant and stubborn pests to deal with. They contaminate food, spread bacteria like salmonella and E. coli, trigger asthma and allergies, and reproduce at an incredible rate — a single female and her offspring can produce hundreds of roaches in a year.
They're nocturnal and hide in cracks, behind appliances, and inside walls during the day, so what you see is only a fraction of the problem. By the time you spot roaches in the open, the infestation is usually well established.
The Causes
What Causes Cockroach Infestations
In the GTA, German cockroaches are the most common indoor species — they hitchhike into homes in boxes, bags, used appliances, and electronics. Once inside, they thrive in warm, humid areas near food and water: kitchens and bathrooms are the main hotspots.
Apartments and multi-unit buildings are especially vulnerable because roaches travel between units through shared walls and pipes. American and Oriental cockroaches often enter from the outside through drains, basements, and ground-level gaps.
What Marsh Does
Thorough Inspection
We inspect kitchens, bathrooms, and hiding spots to determine the species, the extent of the infestation, and the main harbourage areas.
Targeted Baiting
We apply professional gel baits and insect growth regulators in cracks, crevices, and harbourage areas. Roaches feed and carry bait back to the colony, eliminating it from within.
Crack & Crevice Treatment
We treat the hiding spots where roaches live and breed — not just the surfaces you see — to reach the entire population.
Follow-Up & Prevention
Roach control often requires a follow-up visit to eliminate newly hatched roaches. We also advise on sanitation and exclusion to prevent re-infestation.
What to Expect
What You Can Expect
We respond within 1 hour and usually inspect within 24 hours. Cockroach control typically requires 1–2 visits over 2–4 weeks, because eggs hatch after the initial treatment. You'll see a significant reduction within the first week, with full elimination after the follow-up.
You'll get clear instructions on what to do before and after treatment, and a prevention plan to keep roaches from coming back.

When to Call
When You Should Call
Call immediately if you see roaches (especially during the day, which signals a heavy infestation), find droppings in cupboards, notice a musty odour, or see egg cases. Roach populations grow fast and the longer they're left, the harder and more expensive they are to eliminate.
