cockroaches

I've had a bad cockroach problem for a long time, and when I put the poison bait pellets all around my apartment, within two weeks all the cockroaches were gone.

I live in eastern NC and we have what we like to call water bugs but are enormous flying roaches. I put tablets on top of all my window and door molding (somewhere safe from dogs and cats) I would say it took a week or two but I haven't seen any sense. It has been 3 summer months.

It works!

Our problem was silverfish in the master bathroom. Then they spread to the bedroom. GRR! I was SO mad b/c I couldn't seem to find the right bug killer. Harris Famous Roach %26 Silverfish killer works. Here's what you need to know. Silverfish love water and paper. If you've got a stack of magazines or newspapers for example time to toss. We also found they come UP from the drain!! GRR! This stuff is poisonous so you can't leave it out where someone could come into contact with it. I wore gloves. I placed 2 discs on the top of the door frames, at the edge of the drains of sinks/tubs that were not in use, I tossed them behind bookcases and electronics. Counting the preclean up, placing of the pellets, it took about 4 hours. That was 6wks ago. The directions on the box tells you the bugs WILL BE DRAWN to the pellets. We never saw any roaches-thank God but I feel like for a short while after placing the pellets down we saw more silverfish. Be patient. We're at 6 weeks now and we haven't seen on in more than a week! Progress! The box comes with many pellets. We have them stuck back in case we have to reach for it again. I'd encourage others to try it if they are in need. Just a few dollars-not much to lose.
