I have used more expensive products, and I find this to be just as effective, if not more than most .

Professional Pest protection

This provides a professional level of protection from all kinds of ants, spiders, roaches, and scorpions. It works for at least 4 months and was recommended to me by a maintenance man. I decided to get rid of my pest control company and do it myself, because it is premeasured and easy to use. And the price is very reasonable from Wal-mart.

I followed the guide on this and I also sprayed it across my baseboards throughout the house around windows in and out of my home .I paid special attention to the at plug-in outlets I poured some on a rag, and I wiped it around the area of the plug-in outlets For about 3 days, I had to clean up quite a bit of the dead roaches. I no longer have roaches
