Prevention And Control
Cockroaches are a pest and a danger to public health because they can:
- Spread diseases and germs
- Pollute food with droppings
- Damage things such as cloth and books by chewing
- Leave a mess and foul musky odor with their dead bodies, old skins and droppings
Cockroaches are widespread, and are one of the hardest household pests to control. Four types of cockroaches cause problems for people:
- Brown Banded
(Described in detail below)
Cockroaches will eat just about anything. They prefer to live in warm, damp areas like sewers, bathrooms, cabinets, furniture, electrical appliances, basements, porches and crawl spaces.
It is also important to be aware that nymphs (baby cockroaches) look different then the adults.
The best signs are live cockroaches, but you should also look for:
Small, leather-like egg cases
- Old skins shed by the nymphs as they grow larger
Droppings along runways that look like coffee grounds
Brownish stains along cracks
Sour, musky odors
Control With Insecticides
Temporary control can occur through insecticides:
- Contact sprays will kill cockroaches on contact. They may last on surfaces up to a few hours or more
- If sprayed in kitchen or bath areas, wash areas well
- Residual insecticides may last a few weeks or months and come in different forms
- Apply residual sprays into cracks, crevices and along runways as the label directs and keep out of reach of children and pets
- Dusts are used between walls or cracks and crevices
- Use only in dry, void spaces under cabinets, stoves, TVs, stereos, refrigerators and where it will not contaminate food
- Baits can be used where there is little else for cockroaches to eat
Remember: Always read the label carefully before buying to make sure that it is right for your home. Follow the instructions on the label. Always keep insecticide out of the reach of children and pets.
