Too much of cockroaches in my house. they swamp around after we turn of the lights?

-Do you have any suggestions? there is a small baby at our home(1.7 years) so we avoid any poison or toxic sprays.Use plain corn meal. Put about a teaspoon full in every corner of the area including the cabinets and drawers. Leave it there for a while and they will be gone.Cleanliness is a huge help, but you can try "Roach Food." The Roach Food is a mixture of boric acid, white flour, and granulated sugar. Another solution is P.F. Harris Roach tablets. They contain boric acid and a lure. Dust a fine coat in cupboards, under sinks, around toilets and any cracks, corners or hollow spaces. Or you can try Roach Bait. Cockroach bait is either housed in a childproof case or applied as a gel and contains a slow-working poison mixed in with an attractive (for cockroaches) food. Place the bait in an area where you know cockroaches will encounter it.



The goal is to kill them in masses, faster than they will multiply. This may only mitigate the issue and not entirely solve it. If the issue persists, you should probably get an exterminator.
I too have tons of cockroaches in my house. i recommend buying cockroach bait, which are traps that contain, substances that cockroaches think are food but are actually poisonous. heres a picture. http://lh6.ggpht.com/_yApw4gLxzGU/SaKKtx鈥?/a>



the poison in the roach bait is located securely inside the shell, so there isnt much threat of poisoning to human beings.
We had cockroaches at our house too.When we turned the lights off they came out of the unused shower hole.Try pluging the sink/both/shower holes with plugs.We don't have any cockroaches anymore.
Just take care in covering of the drainage properly.

That is the very source of entry of cockroaches.
Soapy Water in kitchen sink every night.
Boric Acid.
