How come cockroaches reappear again after 2 months I bomb the apartment?

Question

Why is it that when I bomb the apartment I dont see cockroaches for 2 months... but after 3 months they reappear again?

Answer 1

Several reasons.....
the cockroach eggs have hatched out. Or.. your neighbors still have them and they are getting into your apartment again because of them.
When living in an apartment it is really hard to rid your home of roaches. Everyone would have to do it at the same time. Even people that live in homes that are separate have problems like this. You can exterminate your house and they will only come back a few months down the line after your neighbor exterminates theirs. They come back to your home then. It is really hard to rid your home from them. I put out bait all the time and spray under sinks with roach killer you buy in the store that says it will continue to kill. I would have done this after you bomb your place.
Exterminators now days cannot use the strong stuff that did rid homes of them. It is unlawful to use now. So all we have are the bombs and traps, and sprays to do it now.

Answer 2

They hide in walls ,furniture,appliances ,basements
You need to get real agressive or it wont work,
Buy bait trays and put them everywhere you see them,
change them evey two months, and smack em with
a fly swatter every time you see them,dont leave any food laying out,,wash all the dishes,and use boric acid in the
bottom of your cabinets and around all of your baseboards

It dosent work unless you are committed to rid them,
It takes time ,,,but I took a roach infested house into
being completely roach free...I am serious
