Spider Roach Killer Question

[aaron_cg]

Made it back from Christmas and go to unload the dishwasher and boom. 20 +/- roaches all in there.

Talking to my mother in law, she uses a product that comes in powder form, that she mixes in a gallon pump sprayer and it works great. She specifically said its for spiders but has worked for roaches as well. Problem is, she doesn't know what it is, and the feed store she bought it from last time went out of business.

Anyone have any good ideas? I put down some diatomaceous earth behind the stove, pulled out the dish washer and fridge, and along where the tile meets the wall. Also put out a few sticky traps in areas where the roaches can get to them but the other animals can't.

Now, here is the issue. We have 2 cats that free roam, as well as 2 dogs that are only kenneled while we are at work. The snakes are away from this area, as are the T's and scorpion. So they aren't a big deal.

Any tips are greatly appreciated.
