Does boric acid kill roaches?

I have tried everything I can think of and I still have these horrid roaches in my house.

Boric acid will kill roaches but it may take a short while. Sprinkle boric acid in dark places, underneath refrigerator, stove, and any other place you think necessary. Be careful if pets and children are in household. Roaches will come out at night and walk through acid and ingest it.

It will kill roaches or at least repel them but you have to spread it everywhere and it gets to be kind of a mess. You should use the roach hotels.

Roaches adapt quickly, so it's hard to keep up. Boric acid is very effective, provided it is used properly. Check out the University of Kentucky's article on Cockroach Elimination.

Yes, it does! Best, because they find it yummy, but it doesn't kill them outright, they carry it back to their nests. However, a serious roach infestation requires serious intervention.

Yes, boric acid will kill roaches. Put all around the house. Under the sink, in crevices and under counters. Sprinkle boric acid powder into the baseboards and anywhere there might be a little damp area.
