Pretty sure THEY PLACED BUGS AT MY HOUSE in attempt to earn my business.
I've always sprayed the perimeter of my home by myself and have NEVER had a pest problem.
These guys came knocking recently with their pitch about "we service all your neighbors, etc"
I explained that I was not interested in service, but the guy persisted.
"Yeah. Many of your neighbors have not seen critters inside their homes yet, but look at this guy here!" --- he pointed out a spider right next to my front door.
A few days later, I found another spider by the sliding door to my yard.
Then that evening, I had a roach in my bedroom! I've never had bugs upstairs ever!
So... for a few years, spraying on my own has worked just fine, then these solicitors show up and all of a sudden, I keep spotting bugs around my home? Hmmm.... I can't prove it, but the situation is a bit suspicious.
