In order to assist my son, i did some asking and roaming around to check how we could eradicate these insects from his room. Seldom as it may, still it appears...and flies. Here's what i gathered. In order to sustain itself, cockroaches need H2O aka water, of course food and the warm closed locations. Let us deal with each of these three;
1) H2O - Make sure there are no leaks in our faucet. Regardless of whether it is in the kitchen sink or our bathroom. Also, my son and myself have one rule in our simple abode. "If we can not afford to wash our dishes, then we do not have the right to use a plate or a spoon." We practiced that since Vincent learned how to wash dishes. If we can make time to sit and eat, then we should make time to wash our dishes as well. Hence, no dirty plates or spoon or utensils in the kitchen sink particularly and specifically at night. I don't care even if it will be submerged in overflowing water. I had one rule in our little abode. Be responsible to clean your mess, no matter how small. Fortunately, Vincent and myself as well had been diligent to that self imposed rule. My tip, make sure you really squeezed that sponge every time it is used. We also pour it with boiling water on a regular basis. By sponge i mean the one we use to wash our dishes.
2) Food: Cockroaches will eat anything that comes its way. From an inch of paper to card board to crumbs to human food. Gluttony indeed. Hence, it would be an advantage to make sure the food are sealed tight in a hard container. Not plastic bag or anything like that because cockroaches will just eat its way from the plastic or paper to the glorious fiber of the food itself. Also, make sure ovens are free of grease. Cockroaches love them.
3) Warm closed environment. Could be a cabinet, a house of a building. They love papers, cardboard, clothing. They lay their eggs anywhere. The most that we can do is to clean regularly.
Of course, insecticide could also help. However, the main recourse really is to make sure there is a regular clean up. For busy people, it will be easier said than done. But then, we always try and try until we finally perfect it.
I will not put a picture. I hope you do not mind. I do not like the sight of this insect as well.
Always take care of your selves.
