Signs of German cockroaches in the property

Activity in kitchen or bathroom

German cockroaches are almost exclusively found indoors, primarily in kitchens, bathrooms, and areas with warmth, moisture, and food sources.

Cockroaches near appliances

Seeing cockroaches around or under refrigerators, dishwashers, ovens, or microwaves, warm appliances with access to food debris are prime harborage sites.

Droppings in cupboards or drawers

Small dark droppings resembling black pepper or coffee grounds in kitchen cupboards, drawers, or behind appliances.

Egg cases in crevices

Small brown egg cases (oothecae) found in tight crevices, behind kick panels, or in the joins between appliances and cabinetry.

Musty or oily smell

A distinct musty or oily smell associated with a larger German cockroach population, most noticeable in confined areas like under sinks or behind appliances.

Commercial kitchen or food service activity

German cockroaches in a commercial kitchen or food service environment, a compliance and health risk that requires prompt treatment.

Treatment overview

How German cockroach treatment works

German cockroach treatment uses gel bait applied to harborage points, combined with residual spray in affected areas. Gel bait is the most effective method for German cockroaches as it targets the harborage sites directly, cockroaches feed on the bait and share it within the colony, eliminating the population more effectively than spray alone.

Inspection and harborage identification

We identify the key harborage areas, behind appliances, under sinks, in cupboard hinges, and other warm, humid locations, before applying treatment.

Gel bait application

Registered gel bait applied to harborage points throughout the affected area. Bait is placed where cockroaches are most active, not in open areas.

Residual spray treatment

Residual insecticide applied to surfaces in affected areas where appropriate, targeting cockroaches moving between harborage sites.

Aftercare and follow-up

We confirm preparation and aftercare requirements, and advise on whether a follow-up visit is recommended based on the infestation level.

Common questions

German cockroach treatment, questions we're often asked

German cockroaches are an indoor species, small, pale brown, and almost exclusively found in kitchens, bathrooms, and warm indoor environments. Wood cockroaches are larger, darker, and primarily outdoor insects that occasionally enter properties from the exterior. They require different treatment approaches.

Gel bait is more effective for German cockroaches because it targets harborage sites directly and is shared between individuals in the colony, reaching cockroaches that spray alone would not contact. Spray alone can cause cockroaches to scatter and re-establish elsewhere.

Activity typically begins to reduce within 1-2 weeks as the bait takes effect within the colony. Significant reduction should be visible within 3 weeks. For heavier infestations, a follow-up visit may be needed 2-3 weeks after the initial treatment.

Yes, gel bait is applied in harborage sites away from food contact surfaces, and residual spray products are selected for the environment. We'll confirm specific precautions for your property when booking.

In most cases you do not need to vacate for a German cockroach treatment. We'll advise on any specific requirements when confirming the booking.
