Means to Prevent Reinfestation of Cockroach

Put food away. Keep food containers sealed, and don't leave food out for extended periods -- don't even leave dirty dishes overnight. * Empty trash regularly, and keep trash away from the house. * Fix dripping faucets or leaks. Cockroaches are attracted to water. * Put naphthalene balls on corners. Roaches hate their smell. * Prevent bugs from coming up the drain. If you believe that the cockroaches are coming up your drains, pour regular, cheap bleach down the drains before leaving the house in the morning. For a stronger solution, mix 1 part borax with 3 parts bleach. * Move logs and other debris away from the outside of the house. Cockroaches love piles of wood and other convenient hiding places, and as the weather turns colder, they'll migrate inside the house to keep warm. * Seal cracks in exterior walls. Keep roaches out of the house by blocking their entrance. * Seal cracks everywhere you can inside your house. This takes time, but the payoff is great, because you eliminate most of their favorite hiding/breeding places. You'll need a lot of caulking, so use the big tubes with a caulking gun. Fill every crack inside every cabinet; fill the cracks on both sides of floor, door, and window moldings; fill all openings around pipes in bathrooms and kitchens. This makes a big difference and makes the whole house feel cleaner. Use a professional product. You can find many professional products online. Professional baits, glue traps with pheromones, and professional sprays are far more effective then products bought at a local home store. Cy-Kick CS is a micro-encapsulated product that is very effective against roaches. * If you buy an exterior bug spray, it will work inside much better. To spray it, put it in a spray bottle or a pump-up pressure bottle and spray the solution in the kitchen cabinets clockwise while holding your breath. Spray quickly and run out and leave the windows closed for a day. Reapply bait to avoid re-infestation by new hatchlings. Re-bait three to four weeks after the initial treatment, to ensure that new roach hatchlings have fresh, palatable bait on which to feed and kill themselves. Refer to a professional exterminator for faster treatment. A seasoned professional can usually eradicate a roach infestation faster than a homeowner by virtue of experience. German cockroaches are often elusive, reproduce quickly, and pose numerous health hazards. For these reasons, it is most effective to allow a professional to handle their extermination.
