Because they reproduce rapidly and can enter your home in mass numbers, roaches can be difficult to control. Once inside, they can destroy books, photographs, electric appliances, and furniture by leaving their unsightly droppings causing a foul odor. These insects are known to spread bacteria, carry parasitic worms, and other diseases. As they forage for food, they can deposit germs and bacteria on counter tops, dishes, and in food, which can cause food poisoning, dysentery, or diarrhea. Some people are allergic to roaches and medical studies have shown that cockroaches are responsible for childhood asthma.
How to control cockroaches
Use preventive measures to control cockroaches successfully. It is easier to prevent a cockroach invasion than to control an established one. Preventive measures require care, planning and continued effort to be successful. A clean home reduces the chance of cockroach infestations and the need for pesticides, but will not always prevent invasions from outside sources.
A Clean Home Reduces Chance of Roach Infestation
Non-chemical Roach control
You may be able to control cockroaches without using chemicals.
Most of these are fairly inexpensive:
1. inspection 2. sanitation 3. exclusion 4. cockroach traps 5. eliminate hiding places 6. cockroach traps
Inspect regularly and thoroughly to locate conditions which invite cockroach invasions. Examine all known or suspected cockroach hiding places and incoming materials.
Good sanitation, both indoors and outdoors, effectively limits cockroach populations. Do not leave unwashed dishes, kitchen utensils and uncovered food out overnight. Clean up all spilled liquids. Clean areas beneath cabinets, furniture, sinks, stoves and storage bins where tiny particles of food may accumulate. Keep kitchen garbage and excess trash in container sand remove them regularly. Store dry pet food away from the kitchen and other foods. If you feed pets indoors, remove the leftover foods immediately. Clean outdoor garbage cans frequently, along with platforms or slabs on which they are kept.
Seal any cracks of 1 /8 inch or more in the foundation and exterior walls. Check the caulking around air conditioning units, windows, doors, pipes or other openings into the home. Repair cracks and holes in floors, walls and ceilings. Seal openings around plumbing fixtures, furnace flues, electrical outlets, windowsills and walls, and along baseboards and ceiling moldings. Repair leaky water faucets and pipes.
Eliminate hiding places
Keep yard trash and stacks of firewood away from your home or garage to minimize the chance of cockroach invasion. Paper, cardboard, lumber and firewood in the home provide excellent refuge for cockroaches.
Trapping can reveal the hiding places and the seriousness of the infestation. Trapping alone will not eliminate cockroaches, but should be used with preventive measures for better results. Many inexpensive cockroach traps are available. They are easy to use, disposable and contain no toxic insecticide. Most are box shaped and coated with a very sticky adhesive inside. Some traps may also feature slow release food attractant. Cockroaches enter the trap when detecting the food odor and stick to the adhesive. Place traps where cockroaches are likely to travel. Change the trap’s position if no cockroaches are caught after two or three nights.The number of traps required will depend on the kind of cockroach present and location of the infestation.
Chemical Roach control
To control cockroaches with insecticides, find their daytime hiding place and thoroughly treat those areas. Regardless of the insecticide chosen, chemicals placed in or near regular hiding places provide much better control than those placed where cockroaches move only occasionally. Since some cockroach species invade homes and buildings from outside, they may reinfest dwellings once the insecticide dissipates. To solve this problem, outdoor populations must also be controlled. The type of chemical selected and the application method used depend on the location and nature of the infestation. No one chemical handles all cockroach problems, but a combination of various types is effective.
