Ants! (1977)

Originally titled It Happened at Lakewood Manor, later incarnations of this horror cult classic ditched that unwieldy title in favor of one that gets straight to the point--Ants! (1977). When a toxic waste dump turns microscopic crawlers into hyper-aggressive monsters, Suzanne Somers and Robert Foxworth have much more to fear than a ruined picnic basket. In one scene, the Three’s Company favorite finds her peachy skin covered by a blanket of pesky insects--at least the ants get to have a good time.
