[sidebar]When looking at four year’s worth of bed bug incidents reported in the city of Philadelphia, researchers found that infestations occured the most in August and the least in February. Turns out warm weather primes the pests to grow at a quicker rate—even quicker if they’re grouped and not isolated, finds a separate study out of North Carolina State at Raleigh—while colder temps kills them. In fact, if you have a bug problem, researchers suggest sticking them in the freezer. These skin-crawling studies are the first of many researchers hope to conduct in an effort to identify better, cheapter control methods. Until then, enjoy the freezing cold (and these otherwise preventive tips.)
