Dearborn Cockroach Infestation — What That Single Sighting Really Means
Cockroaches are nocturnal insects that spend most of their time in hidden harborage sites — behind refrigerators, inside cabinets, under sinks, within wall voids, and inside electrical equipment. A cockroach seen during daylight hours indicates harborage sites are overcrowded.
The two species our Dearborn technicians treat most frequently are the German cockroach and the American cockroach — each requiring a different approach. German cockroaches live and breed entirely indoors, reproduce at high rates, and are prone to developing resistance when repeatedly exposed to the same insecticide. Species identification is the essential first step.
Avoid Spraying Before Professional Treatment
Applying aerosol sprays before a professional inspection causes cockroaches to scatter and move deeper into wall voids, making accurate assessment and treatment more difficult. Call a specialist before attempting any DIY treatment.
Health Risks
- Pathogen Spread: Cockroaches harbour and mechanically transfer bacteria — including Salmonella, E. coli, and Staphylococcus — across food preparation surfaces, utensils, and stored food. A single foraging cockroach can contaminate surfaces it crosses.
- Respiratory Allergen Exposure: Cockroach droppings, shed skins, and saliva are recognized allergens associated with asthma aggravation, particularly in children.
