I had a beg bug problem that slowly reared its bites throughout a period of 4 to 5 weeks. After finally figuring out it was a bed bug issue, I quickly called CAIN (through a referral from a friend).
The owner was very thorough in explaining to me the process of exterminating these bugs and gave me peace of mind that this is a small problem relative to other pest infestations. I called at 5 p.m. and he sent an exterminator over at 8 a.m. the next morning.
Unlike other exterminator companies, CAIN offers just 1 spray (very quick - less than 15 minutes in my condo unit), but 1-year guarantee. If you notice the problem persists or returns, they will come to spray as many times as needed - at no extra charge. Other companies just offer to spray your home twice within a period of a month.
I highly recommend CAIN to anyone unfortunately experiencing a bed bug problem. The bugs were gone within a couple of weeks after!
