How to Get Rid of Cockroaches and Prevent Them from Coming Back

Cockroach infestation in the kitchen.

Cockroach infestations are a serious concern for Calgary homeowners. These resilient pests can spread quickly, contaminate food, trigger allergies, and carry harmful bacteria. If you’ve spotted even one cockroach, there’s a good chance there are more hiding in cracks, crevices, and wall voids. Here’s how to eliminate them effectively and keep them from coming back.

1. Identify the Source

Start by inspecting key areas such as kitchens, bathrooms, basements, and laundry rooms. Look behind appliances, under sinks, and around plumbing lines. Cockroaches are attracted to moisture and food debris, so targeting these areas is essential.

2. Clean and Sanitize Thoroughly

A clean home is your first line of defense. Remove food crumbs, store food in sealed containers, wipe down surfaces, and take out the garbage regularly. Fix any leaks or standing water to remove their water sources.

3. Seal Entry Points

Cockroaches can squeeze through tiny cracks and gaps. Use caulk or weatherstripping to seal around doors, windows, baseboards, and utility lines to block their entry.

4. Apply Targeted Treatments

Use professional-grade baits and residual insecticides in problem areas. Gel baits work well because cockroaches feed on them and bring the poison back to their nests. For severe infestations, foggers or dusting inside wall voids may be required.

5. Hire a Calgary Pest Control Expert

Cockroaches can be difficult to eliminate completely. A licensed pest control technician can identify hidden infestations and use safe, effective treatments to eradicate them. Local Calgary professionals understand seasonal patterns and common entry points unique to the area.

6. Maintain a Prevention Plan

Even after elimination, regular cleaning, sealing gaps, and monitoring are crucial. Consider routine pest control inspections to ensure they don’t return.


✅ Final Tip: The key to long-term cockroach control in Calgary is a combination of sanitation, sealing, and professional treatment. Taking quick action at the first sign of activity can save you time and prevent larger infestations.
