Cockroaches can be found in both commercial establishments and household settings. The most common domestic cockroach species found in Canada are the German cockroach, Blattella germanica, American cockroach, Periplaneta americana, brownbanded cockroach, Supella longipalpa, and Oriental cockroach, Blatta orientalis L. Roaches may transfer disease-causing germs by crawling over food preparation areas and may also cause homeowners to develop allergies that may lead to asthma.

Home Remedies

Traps

Home remedies for trapping and eliminating roaches have been around for years and may include sticky traps and jar traps. Appropriately labeled and registered products for domestic use are readily available in stores. These products are available in various forms such as aerosol spray, baits, or dusts. Remember to read product labels prior to application and follow the label instructions.

Baiting is the most effective and safest of all the control methods, though to effectively control cockroach infestations, multiple baits must be set out and placed correctly. Baits must be placed in habourage and foraging sites, close to other points of entry. Baits should never be placed in open, exposed, or extremely hot or wet areas.

Remember to replace the baits as needed to ensure effectiveness. Of the available solutions, traps are the least effective. Traps generally have openings at each end and are lined with an adhesive used to immobilize the cockroach. Cockroach traps are best used as indicators of infestation in the home.

Sprays

For quick, direct knock-down, aerosol insecticide spray can be used by a homeowner. Always use an appropriately domestic-labeled spray and follow application instructions on the label. Spray affected areas only after removal of any kitchen or bath items that may become contaminated. Thorough application of cracks, crevices, and areas behind appliances and under sinks with dust forms or spray will kill active cockroach population and prevent future infestation.

Homeowners should avoid using foggers, bombs, and commercially registered insecticides for safety and application concerns. Improper insecticide applications can cause cockroaches to develop resistance to the products or cause change in their behavior, making control of the pests difficult, leading to expensive and repeated treatments.
