They can be the size of a poppy seed, and they could be hiding in your bed, chair, or even your wall socket.
The National Pest Management Association has reported a 71 percent increase in bedbug infestations in the U.S. since 2001.
Dogs trained to track down bedbugs search a hotel room in one to two minutes.
"A lot of our dogs are rescue dogs," said Jose "Pepe" Peruyero, CEO of J&K Canine Academy.
"We want to, ideally, have a dog detect as few as one egg or one bedbug in a room," he said.
The canine nose is just one weapon in the fight against the superbugs that are turning up in more homes, hotels, nursing homes, even movie theaters.
"Bedbugs have evolved resistance to many of the insecticides that we're allowed to use to kill them," said Dr. Phil Koehler, an entomologist at the University of Florida.
Dr. Koehler and his team developed a pesticide-free system. It works like a bedbug oven.
"The idea is that it only takes about 113 degrees Fahrenheit to kill bedbugs," said Dr. Koehler.
He builds a styrofoam box around infested furniture, heats the enclosed area to about 140 degrees.
The entire process takes two to five hours, with no damage to furniture. In nine of 11 tests, the system killed 100 percent of the bedbugs. The cost of the entire re-usable system is $300.
Dr. Koehler says using oil-based space heaters eliminates the risk of fire. Standard ways to get rid of bedbugs involve replacing furniture or using pesticides.
