Unfortunately, Ryan is right about the speed at which roaches procreate, so your mom might need to call in a professional for a thorough inspection. However, depending on the size of the roach as well as the location and frequency with which you're seeing them, your mom may want to consider more than the spray to tackle such a persistent problem. Our System Creator offers cleaning tips as well as specific product recommendations to attack, control, and prevent bugs: http://www.raidkillsbugs.com/en-us/solut...

You need a professional exterminator. If you have had them for at least five years then you have hundreds if not thousands in your walls. They populate very fast.

I live with my mom, being that I'm a teenager. She buys Raid roach spray for our roach problem. It works okay but she's usually the only one spraying in a house of 4. I was just wondering if anyone had any tips on how to get rid of the roaches for good using this spray and other tips. I have heard that roaches/insects can become immune these things over time. We have used Raid for a while-maybe 5 or so years. When we spray the roaches, it may take up to 30 seconds for them to twitch and fall out then die. We have used it for so long that it's become apart of our grocery list. I'm so sick of them. Occasionally they'll crawl on me and I have brush them off and jump around. I hate bringing my friends and having them think we are dirty people. Any help?
