DIATOMACEOUS EARTH, not toxic and will kill roaches and others stuff but will not hurt your pets or kids-- in fact, if your pets have a tapeworm, the DE will cause them to expell it. this is a miricle from our earth. My husband has been using it for years in the yard and he finally stopped me from using dangerous toxic pesticides in the house. I did not believe him that it worked. It does.
we use it everywwhere, in the yard, under the house , in the kitchen. the bugs get it on their feet and it enters their digestive system and acts sort of like cut glass and they just die. very effective. kills spiders too. we dust about every 2 -3 weeks or so. you can buy it with an extra pesticide too if you want for very fast resuts but it works very well. not costly. earth friendly.
