First of all save all the trouble and money and hire a professional rather than renting a cheap heater fan that will not kill the bed bugs. I had a problem with these annoying bed bugs. Couldn't sleep in our bedroom because of the awful bites throughout the night. I have kids and I didn't want the chemical treatment because I do not feel safe using them at my home and upon research they do not kill the bed bug eggs and will not penetrate the wall and baseboards. When I called and booked an appointment on July 31, 2019 Armand came over in half an hour and gave me an estimate. He was very professional and I like the fact that they specialized only on bed bugs. We agreed on a price and warranty of 90 days as what was on the advertised on his website. The next day I decided to treat the whole house top to bottom to kill all the bugs and to wherever they are hiding at once with intense heat. This way we are disinfecting the whole house at once. He came and his help at our home before 10am with huge tanks and ducts that will heat up the basement , main floor and second floor for hours. The heat treatment lasted for around 5 hours. So far we are doing good. After the treatment I cleaned the house and saw a couple of dead bugs. So far No more bites at night. I really hope no bugs and eggs survive and I don't that I wont ever have to call him again meaning he did well on the first treatment. So far I am happy customer.
