They can contaminate food making it unfit to eat. They eat food, glue, leather, bookbindings, and even television and microwave wiring. Although cockroaches are active at night they can be seen during the day if disturbed or numerous. Cockroaches are 1/2 inch to 1-1/2 inches long, have flattened, oval bodies, long antennae and a head hidden by a shield-like covering.
There is always a potential to move cockroaches from one building to another. Cockroaches or their eggs could be in a bag or box, on clothing, in furniture or merchandise that is purchased and carried into buildings. In some instances cockroaches crawl in from the outside or from a break in the sanitary sewer.
These sanitation practices and building modifications can minimize infestations:
- Keep food in closed containers, including pet foods. Pick up pet dishes after pets have eaten.
- Fix leaky pipes, faucets and roofs since most cockroaches need water.
- Seal cracks around kitchen cabinets and countertops. These very small cracks provide a home for cockroaches.
- Food containers that are recycled need to be rinsed of all food waste.
- Do not allow boxes or newspapers to clutter rooms; leave space between packages.
