Boric Acid powder for roaches.

one of my neighbors sprayed for roaches. The next day, I saw a roach. I think had my house sprayed but then saw one 3 months later. I laid out boric acid powder on my kitchen counters, because this was the only place I could get to easily. Once a week, wipe it away and sprinkle on new. I've donenthis for a month and haven't seen anything. Cheap and effective. Use in multiple areas where you can easily get to and put on fresh powder. Sprinkle! Does not have to be heavy or lots of an amount. The key is continuity and fresh applications, not the amount.... at least for me and the few I saw.

Gets rid of ants for years !

This works like magic in getting rid of ants. Two years ago we put some of this in small plastic dixie cups and located a few around the inside of our house and sprinkled it around the outside of our home. Within 2 days the ants were gone and 2 years later still have not returned. It's safe and economical. I bought this to keep on hand for our son's house.

99.9% Fine Granular Powder Boric Acid, 10 Lb, H3BO

I ordered this to kill roaches. They were concentrated to my boyfriend's room because he was dying and too weak to squish them, so you know I am going to eliminate the creepy pests for good with this stuff. wasn't much I could do until he went to the hospital. This is the best weapon against roaches,
