Hi. Just wanted to testify to the nuclear effectiveness of borax, peanut butter, sugar, and water against cockroaches. I mixed about a pound of the stuff in random ratios about 6 months ago, dropped the goop on old magazines, and stuffed it behind the water heater in the garage (the cockroach headquaters).
So far, I’ve only dealt with two cockroaches - one that flew in from the front door, and one that somehow made it into the house from the garage. Usually, I’d have seen at least several dozen roaches by now, but they’re all gone.
It’s so effective that I was positively giddy today about making more of this mixture. I made at least 5 pounds today of borax-peanut butter-sugar-water mixture and exhausted my entire box of 20 Mule Team Borax. I guess I won’t be seeing cockroaches from the garage for the next decade, at least :p.
Again, I cannot stress how miraculous this mixture is. I was initially wary about having to go buy borax and mix it up, but this stuff really works. I initially tried cockroach sprays that “kill on contact,” but these things are useless. I have to spray a cockraoch for 30+ seconds for it to stop running around. And even then, it’s still on its back wriggling around, and if I leave it alone for 24 hours and come back, it’s gone. Kills on contact? What a joke. Plus, I hate the odor of cockroach sprays. Borax is safer and has no odor. Thank you Cecil!
