You enter the kitchen and turn on the light to prepare a midnight snack when suddenly you notice a fat German roach scurry across the floor. It's time to learn some Terminator tactics for how to kill the German roaches having picnics in your living quarters while you are fast asleep.
German roaches are one of several roach varieties that often invade homes, but smaller than the common American roach, growing to slightly less than an inch in length. Just one German roach gaining access to your house means that within a few weeks you can be overrun with roaches.
One of the most effective, but time-consuming ways to kill German roaches is to get a full-sized caulking gun from the local hardware store, and about 10 to 20 cartridges of white acrylic caulk and go about the task the sealing every nook and cranny that might provide an opening into the house through the walls, cabinets, doors and windows.
Get a supply of boric acid from the hardware store which is very effective in helping to kill German roaches. Remove all children and pets from the area as you sprinkle some along the baseboards, in the spaces behind your appliances and in the corners inside your cupboards. Any area that you sprinkle with boric acid must be completely dry or the acid will lose its potency. Discard any extra boric acid or keep in a closed container away from children and pets.
Your local supermarket is a good source for commercially produced roach motels and glue boards which each contain a sticky surface to trap German roaches as they scurry past. This same sticky texture could prove problematic if touched by children or pets, so be sure that you place the motels and boards well away from curious hands and paws. Commercial roach sprays can be effective because once you apply the spray, they leave a chemical trail that will kill German roaches for several weeks after. Most sprays, however, can prove fatal if swallowed by children or pets, so keep both away when applying this exterminating method and wear gloves for protection.
Crushing roaches underfoot will definitely kill them one by one, although you won't get to the source of the infestation. German roaches are attracted to warm, wet and dark environments and often congregate underneath sinks and appliances like ovens or clothes dryers.
Basic good housekeeping, such as putting away leftover food immediately after use into sealed containers, not letting dishes pile up in the sink or keeping piles of dirty laundry on the floor, can do wonders in preventing German roaches from setting up house in the first place.
As a last resort, if the infestation doesn't subside or gets worse, call a professional exterminator.
