I'm not sure if Orkin is a franchised company or nationally run by one owner. Probably franchised, but I just don't know. That is bound to determine what sort of LOCAL service you'd get.
I dealt with a smaller "local" pest control company for 15 years on our old house. When we found termites in the garage, they gave us 10,000 excuses, but no results. Their contract was worded in such a way as to give them an "out". Their initial bill was $700. (1986) Then there was a $100 per year "follow-up" fee. When I found the termites, we battled with the old contractor for a couple months. Then I turned that over to an attorney and brought in Terminex. They got rid of the termites at the cost of $1850, plus $75 a year henceforth. ( The legal action against the old exterminator netted a refund of all "follow-up" charges since day one, since they were found to have NOT done what they said they'd do. They are now out of business)
My experience with pest control people is that there are more con artists in this field than any business I've ever dealt with. Big national companies USUALLY have corperate standards that the small, local exterminators don't. There are good small contractors, but it's too late when you find out hey AREN'T, 20 years down the road. I like big national companies with a reputation to uphold. It's easier to hold their feet to the fire when trouble crops up.
