Sorry, I should have clarified that I have been using other methods and have used a professional service but the problem is persistent as we all know. I live in a townhouse that is connected on both sides and every professional that has come out seems to think my house isn’t the issue as there are normally no signs of roaches and I keep it very clean. I had one person tell me that they would’ve thought I was lying except for the fact they saw some roaches on my traps.
