Considered pests in homes, bugs serve a greater purpose in the wild, as bees pollinate flowers and giant moths prey on humongous radioactive lizards. Confine insects to their element with today’s Groupon: for $19, you get an exterior home pest-control treatment from Enviro-Tech Pest Services (a $99 value). This Groupon is valid within a 50-mile radius of Dallas/Fort Worth and the Collin County area.

Enviro-Tech Pest Services fortifies home perimeters with environmentally friendly products that both expel resident insects and rodents and prevent them from encroaching into houses in the first place. Fully licensed and insured technicians adapt each treatment so that it will oust the home’s particular pests, including swarmers, carpenter ants, flying ants, mice, fleas, and weevils. Exterminators coat the exterior of the home and all of its potential insect entryways, so the duration of the service depends on the home's size and its number of spider-sized doggy doors.
