Abstract
A vacuum device having a hand-held intake and collection unit and a hand-held heater/air exhaust tube assembly is used to chase and collect pests, such as insects, and their associated allergens from their harborages. The device has a system of filter assemblies which remove contaminants from the air and exhausts clean air back into the surrounding environment.
