Sticky Cockroach Traps

Sticky cockroach traps are effective for monitoring and detecting an infestation. Some sticky cockroach traps contain lure in them to actively attract roaches while some are passive without lures. By monitoring cockroach activity, you can detect if you have a problem, identify any problem areas and what type of cockroach is present in your home. Sticky cockroach traps can be part of an Integrated Pest Management (IPM) plan, where it is incorporated with other methods of control to effectively control and manage cockroach infestations either at home or within a commercial setting. 

Cockroach Bait Traps

Cockroach bait traps are ready to use bait stations that contain a mixture of insecticide and baits to lure the roaches to feed. They are lined with adhesives to trap and immobilize the cockroaches. Cockroach bait traps are the most effective and safest of all the control methods if used properly, though to effectively control cockroach infestations, multiple cockroach bait traps must be strategically and correctly placed. Baits must be placed in harbourage and foraging sites or in close vicinity. Cockroach bait traps must never be placed in areas accessible to children and pets; they must not be placed in dusty or extremely hot or wet areas.

Remember to replace the cockroach bait traps as needed to ensure effectiveness, follow the product label for safety and effectiveness.

Cockroach Spray Treatment

For quick, direct knock-down, aerosol insecticide spray can be used by a homeowner. Always purchase and use an appropriately domestic-labelled insecticide spray and follow safety and   application instructions on the label. Spray affected areas as per label, remove or cover kitchen or bath items that may become contaminated. Clean sprayed surfaces as directed in the label once control is achieved. Strategic and proper application of a cockroach dust formulation or spray in cracks, crevices, and areas behind appliances and under sinks will kill active cockroach populations and prevent future infestations. 

Homeowners should avoid using foggers, bombs, and commercially registered insecticides for cockroach control in homes due to safety and application concerns. Improper insecticide applications can cause cockroaches to develop resistance to the products making cockroach control difficult, leading to expensive and repeated treatments.
