Bed bugs are microscopic creatures that infest both homes and hospitality venues. These critters also love to feast on the blood of hapless sleepers. While these pets were eradicated in the U.S. back in the 1940s, they made a strong comeback in the 1990s. Since then, bed bugs have continued to plague countless homes and hotels. According to industry experts, the resurgence of bedbugs is attributed to several factors. This includes the increase in global travel, along with greater movement of people and migration patterns. The elimination of crucial pesticides has also enabled bed bugs to mate and expand at alarming rates.
