I"ve employed Rove pest control since June in order to get rid of cockroaches that suddenly invaded my very clean home. They appeared to come from beneath the refrigerator. Although Rove has sprayed many times, I tend to see a roach nearly every day. We initially had the red ones, but now they appear to be black. Sometimes they are tiny, and other times about an inch long. I understand that they can enter the home in card board boxes and other packaging of which we get a lot. As you have suggested above, I am not going to keep card board boxes in the house anymore, but take them directly to the recycling. I am really hoping to get rid of the roaches permanently. Is that possible? If so, how do I do that?
