Garden Safe Diatomaceous Earth Crawling Insect Killer, 4 lb Bag

In the phoenix area, I've had problems with scorpions, ants, cockroaches, and silverfish. This is supposed to kill all of them and is non-toxic and affordable. I don't like poison because I have cats and I also don't want to kill beneficial spiders or lizards. I do however have a can of poison for the black widows and any bees that want to build a hive on property. This product is spread pretty thick around my front door where most scorps will try to get in. I also got a sprayer ( RL Flo-Master 1-Gallon Sprayer ) on this site for $4.89 and it works well with this. I mixed the DE with water and sprayed it near the top of the block-wall around back yard. I had to take the nozzle off so it would not clog. The water evaporates quickly and leaves a film of DE on the block.
