Is it worth getting an exterminator for cockroaches?

If you have found cockroaches in your home, the honest answer is almost always yes to calling a pest professional. Cockroaches are among the most resilient pests on the planet, and the vast majority of DIY attempts do not eliminate the infestation but instead relocate it or make it worse.

If you live above a restaurant or any food preparation business, the risk of cockroaches increase because the area is constantly covered in food and requires regular cleaning routines. We've had cases where residential properties got infested as a result of a restaurant next door. In one extreme case, the restuarant closed down and they didn't move any food, letting it rot and attract a massive infestation.

The short answer: absolutely yes. Cockroaches reproduce rapidly, spread bacteria/allergens, and are notoriously difficult to fully eliminate without commercial-grade products and expert knowledge. For any infestation beyond a single sighting, professional cockroach treatment is strongly recommended. For German cockroaches specifically, professional assistance is essential.

Signs that You should call a Pest Professional Now

1. You are seeing roaches during the day: Cockroaches are nocturnal. Daytime sightings mean the population is large enough that competition for hiding space is forcing them out into the open. This is a sign of a well-established infestation.

2. You have found egg casings: A single German cockroach egg case (ootheca) contains 30 to 40 eggs. Finding multiple casings means breeding is already well underway. Each case left untreated will add dozens more cockroaches to the population within weeks.

3. Roaches are appearing in multiple rooms: When cockroaches spread beyond the kitchen into bathrooms, bedrooms, or living areas, the infestation has already grown significantly. At this stage, DIY bait placement alone is rarely sufficient to collapse the colony.

4. You have tried sprays and the problem is worse: Contact sprays kill on the surface but scatter cockroaches deeper into walls and behind appliances. If your infestation has grown after spray treatment, this is almost certainly why. A professional uses slow-acting baits that the roaches carry back to the nest.

5. You live in a multi-unit building: In apartments and condos, cockroach colonies travel freely through shared walls, plumbing chases, and utility voids. Treating your unit alone will not resolve the infestation if the colony spans neighbouring units. Coordinated professional treatment is required.

What does a cockroach exterminator actually do?

A licensed pest technician begins with a full inspection to identify the species, the extent of the infestation, and the conditions contributing to it. Cockroach treatment typically involves:

• Strategic gel bait placement along harbourage areas, cabinet hinges, under appliances, and inside wall voids.
• Insect growth regulators (IGRs) to disrupt the reproductive cycle and prevent nymphs from maturing.
• Residual insecticide applied to cracks, crevices, and entry points for ongoing kill activity.
• Sanitation and entry-point recommendations to prevent re-infestation.
• A follow-up visit to assess treatment effectiveness and retreat if necessary

What does a cockroach treatment cost?

A typical single cockroach treatment for a standard home ranges from $300 to $450 based on severity. Severe or multi-room infestations requiring two or three treatments may cost $350 to $600 in total. Guard More Pest Control includes a follow-up visit in the initial price.
