Have you seen a cockroach in your room that has since scurried away behind the bed or something else in the room, and now you can’t find it? If so, don’t get your hopes up about being able to find and kill the roach.
Once they get out of your sight, cockroaches can be extremely difficult to locate. They are masters at the art of hiding in tiny cracks and crevices so that they won’t be detected. They know instinctively that humans are a potential threat and will quickly hide from them. Keep in mind that the cockroach is probably more frightened of you than you are of it, and it is not likely to come out again until it is dark in your room.
Are you determined to find that filthy cockroach?
But what if you are haunted by the idea of a marauding cockroach loose in your room, and are absolutely steadfast to find and dispose of it?
Try using a flashlight to search the area where you last saw the roach. If you don’t have a flashlight, you can use the one on your cell phone. If you’re able to us shine some light on a cockroach you can get him to start running, making it easier to spot him. Turn over and look under anything that a roach could hide behind. If you are lucky and do find the roach it will run again quickly. So be ready to kill it with a book, shoe, or spray can of roach killer.
If you don’t have any luck locating the disappearing cockroach, you can look for potential escape hatches along the baseboard of the walls. Finding these will also give you an idea of how the roaches are getting into your room in the first place. But getting the roach out of these hiding places is another matter altogether.
Roaches have special abilities to avoid being found.
Roaches have very sensitive antenna on their head which are used to listen to minute vibrations in the air caused by the movement of people or animals. These antenna also allowed the roach to smell the presence of predators. So once a roach is spooked, it probably won’t emerge again for some time.
Also, cockroaches are highly averse to light and will run towards darkness as soon as you open the door or turn the lights on. This is another defense mechanism that cockroaches have developed through evolution to help them survive. If cockroaches were not afraid of the light, they would be easily seen and killed by predators.
What to do if you can’t find the roach?
If you are not successful at finding the cockroach, you will need to use some roach products in order to exterminate him and all of his roach friends. You may choose to put down a couple of roach traps traps around the room, which should lure him and his friends and kill them. In my opinion, however, the best way to kill roaches without an exterminator is by sprinkling some boric acid roach killer around the baseboards of your home.
