After a recent hotel stay, we suspected that we had acquired bed bugs in our master bedroom. We called Addison Pest Control, and they came to our house the next day.
It took about 5 minutes for him to find the bed bugs. He was very well-spoken and reassured us that he could help. He offered to treat our home that very day, even though it was New Years' Eve! This company uses a combination of localized heat and generalized spray throughout the house (baseboards, undersides of furniture, beds). We were worried about toxicity, since we have children, so he gave us time to research, and at our request did careful inspections of the baby's bed instead of spraying it.
We were not sure that it would work. 12 days after treatment we found one dead bed bug on the carpet beside the bed. We have not seen anything since; it is now 3 months since we had treatment.
This company's method worked for us. We have a large house: 2500 sq ft. The whole house had to be treated to get the company's guarantee, hence the hefty price tag. But it was worth it.
I would recommend this company wholeheartedly.
