ZK -“Then one day someone told me about boric acid. So I tried. I poured and poured like there was no tomorrow, into holes and cracks, drawers, shelves, in appliances, under appliances, behind appliances etc. Within a few days they were all B”H gone!!”
Yes Boric Acid works, but nowadays they have the Roach bait and poison which supposedly kills the whole colony. Spray only kills the ones that touch it -not very effective.
