Less than good experience with these folks. My dad signed me up with a door-to-door rep while doing some upgrades to my home and yard. I didn't ever want to be signed up because it's frankly an expensive service to have, let's all face it. But he payed for it so whatever. Several hundred dollars a year so your neighbors will pay you maybe one compliment about how nice your grass looks? In the meantime, you will just gloat over the presence of one or two weeds where you didn't expect them. (That's just a personal problem of mine though.)
The real problem here lies in their ability to have their crap together at their office. I mean sure, they sprayed my garden and killed everything in it. No biggie. So I called to cancel service. They said sure, service is cancelled! I paid my last bill and went on my merry way. Until one day weeks later I got home and they had left me a bill and a stupid sign in my yard saying "keep off till dry" - they had treated my yard again. I called back, they said "we don't have any record of you cancelling your account". Oh I was about to get livid. Then they had the nerve to ask me to pay for the treatment because it had been done. We settled for half payment and I cancelled AGAIN. Just yesterday I got a bill for automatic restart of services next year. We'll see if the 3rd time's the charm... I seriously want these guys to just eliminate me from their database and forget I exist.
The only reason I even offer 2 stars is because when treatment was being done well my grass never looked so good in about 80% of the yard. It seems to be difficult for them to get the corners and nooks and crannies. Maybe they're just moving too fast? I also wanted to cancel because these days I care less and less about the ecological disaster that is the American lawn. Grow food not lawns!
