Bugged (1996)

Bugged! tells the story of a group of bumbling exterminators who are called over to the house of an attractive young novelist to rid her house of insects. Unfortunately, due to a horrible chemical mix-up, the poison spray causes the bugs to grow to enormous sizes, and pretty soon everyone's trapped inside the house and have to find a way to stop the dastardly pests before they start multiplying and take over the world.
