Get rid of cockroaches by taking away their food supply, eliminating hiding places, drying up standing water and using poison. Sealing cracks and other openings to the outside prevents them from entering your home.
- Terminate their food supply
Keep all surfaces in your home free of food spills, including tables, kitchen counters, stoves and floors. Store food in the refrigerator or in tightly-sealed containers. Wash dirty dishes right away instead of letting them sit in the sink. Store garbage in a closed bin and empty it regularly. Avoid using shelf paper and wallpaper, as cockroaches eat the glue that binds the paper to surfaces.
- Eliminate hiding places
Purge the house of clutter where cockroaches hide, especially paper bags, cardboard boxes, newspapers and magazines. Throw out items, such as rags, old clothes, broken furniture and appliances. Seal up cracks and holes where cockroaches can enter with caulk. Put weather stripping around the edges of windows and doors.
- Eradicate water sources
Since cockroaches are drawn to standing water, dry dishes and put them away after washing. Keep sinks, bathtubs and showers dry by wiping them after use. Wipe floors dry after mopping them. Watch for plumbing leaks, refrigerator drip plates and moist soil in or under potted plants. Plug drains with stoppers when they are not being used.
- Utilize poison
Use baits, sprays, gels or boric acid powder to kill any cockroaches that remain. Use the poisons with care. Keep them away from dishes, silverware and food preparation areas.
