I had wasps building a nest in the siding of my house, it was up high so it was hard for me to reach with normal spray so I decided to call a pest control company. I got this from a referral from a friend who previously bought a groupon deal with this company for Ant control. That person didn't have a great experience, but at least he did the job (the reason was they said the deal was only for Vancouver residents, but my friend lived in Richmond and they didn't initially want to honor the deal, but only after a while they said they'd come).
Anyways, I called him on a Sunday and he was able to come the next day, which is surprising since Monday was a public holiday, so at first it was great service. He sprayed the opening with something and said it's "expensive stuff" and that it's residual and guarantees that no wasp will return to that area. It took him 30 seconds to finish the job and he took off.
Well about 1.5 weeks later I noticed some wasps going back into that same nest so I called him back. That morning he said "that's not possible since", well I'm staring right at it and I'm seeing wasps. So he said he'll call me back later since he's on a job right now. The day passes and no call, so I called him back the next day. He said he'll come take a look, but he's really swamped that week and won't be able to make it until next week. But said "don't worry I have your number and I'll call you when I come over". Well, I figured 1 week and the wasps will have built a huge colony by then, so I had to take care of it myself by buying lots of spray foam, hanging outside my window to get at the area, etc etc. I sprayed in the early morning and late evening for about 5 days and the wasps disappeared.
In anycase, I never got a call back from the guy and I took care of it myself, which I should have done in the first place. I thought a "professional" would do a better job but that was wrong.
It's interesting how the initial job he was available immediately but then to follow up and fix on problems he was busy. He knew that any follow up service I would not be willing to pay since he "guaranteed" it to begin with.
