A few months back, I went on vacation with my daughter, son-in-law, and grandkids. Apparently we picked up bedbugs. After returning home, I noticed a few bites here and there on my body. Suspecting maybe fleas or other 6+ legged critters, (as I live with the four legged kind) I spread a little diatomaceous earth around the bed and bedroom carpet. It was time to do that anyway to minimize the dust mites I'm allergic to. After a while I noticed there was nothing to notice, so I didn't give it another thought. UNTIL...
A couple of months later my daughter said she had bedbugs. An exterminator cost them $600, and was guaranteed for a mere 30 days. What a crock! I now believe I had them too, but killed them off with the diatomaceous earth before they had the chance to breed and spread.
Lately I've been seeing cockroaches around the house. (Here in Texass, the locals call them "water beetles", but I know a cockroach when I see one!) Brazen little suckers--one ran right in when I opened the sliding door to the back porch. That was the last straw! It's been raining almost constantly here, so I was waiting for it to stop before putting out the diatomaceous earth. A quick sprinkle around the house, and no more invading cockroaches! They like to invade the garage as well, so I sprinkle a little around the walls. I'm sure there are plenty of dead cockroaches hiding where I can't see them.
50lb bags are the most cost effective, and it lasts forever. To spread it around, I use a big sieve as a scooper, then sprinkle liberally. All around the house's foundation, and wherever else they hide, like wooden fences, near rocks, etc. Inside the house, I spread it under couches, behind appliances, and under the sink. I love that it's non-toxic, and will work its magic while I enjoy not seeing any bugs.
Now if somebody can just find a safe and effective way to rid the lawn of dallis-grass, I'll be a lot less upset about being stuck in the great big barren (physically and mentally) state of TexAss.
