Early exterminators experimented with judicial pest-control solutions, such as serving roaches with tiny eviction notices and suing silverfish on The People's Court. Declare martial law on household pests with today's Groupon: for $50, you get an initial pest-control treatment from Barrier Termite and Pest (up to a $175 value). This Groupon is valid in Arlington, Fairfax, Fauquier, Loudoun, Prince William, Clark, and Montgomery Counties.

Barrier Termite and Pest chases out creepy-crawlies with a full arsenal of insect-slaying weapons. A friendly, certified technician begins the initial pest-control treatment with a thorough home inspection, peeping into corners, cupboards, and antigravity squash courts to ferret out multilimbed menaces and determine which treatment methods are most appropriate for a particular home. Then, the technician will secure interiors and exteriors with mechanical seals, physical barriers, and monitoring devices that can prevent re-infestation by ants, centipedes, millipedes, crickets, silverfish, roaches, and talking spiders.

Though Barrier Termite and Pest sometimes features a discounted price online, this Groupon still offers the best deal available.
