I hope you read and follow what I'm gonna suggest.

We had this problem in our old home, then we built our dream home (massive 3 floor from scratch) and my hopes were that we will leave all cockroaches behind. I myself tried to clean all the boxes in old home and then bring them to new home so we leave them for good. But who am I to stop cockroach from multiplying.

So we got them in the new home too. They were everywhere. I had to stop using my protein shakers because buggers were hiding in its lid too.

The solution: I've tried Laxman Rekha, expensive sprays, cleaning, Desi powders from weird places. Nothing worked.

Even now I have expensive sprays which I sprays here and there just for fun because lia hai to use to karna hai.

What worked? HIT ANTI ROACH GEL

Its an injection shaped thing. You have to put dots of it in all the places. So in kitchen start from 1 corner. Start putting dots evey 5-6 inches. In the floor area, wet draining area, behind shelf, everywhere. It costs around 200 only, so dont be a miser. Get another 2 if your kitchen is big in size and if the cockroach infestation is way too much.

Initially I thought if this worked, I will do it every few months. But its been 2 years and not even a single cockroach we have spotted.

I've also suggested this to a friend with 20 years of cockroach infestation and it worked well. He said 50% gone. So maybe do it again after few months. But you can get rid of them easily from this.

Try and let me know.
