Things You'll Need
Paper or plastic plate
An outdoor bug zapper uses electricity in a grid to shock bugs when they touch it. The bugs are attracted by an ultraviolet light, which lures them onto the grid. Once electrocuted, they fall to the ground and can be swept up or left to biodegrade. A standard indoor bug zapper has a tray that catches the bugs when they fall, which then can be cleaned out to prevent contamination of indoor surfaces. The fitted tray is the only real difference between an outdoor bug zapper and one that is designed to work inside.

Locate a paper plate or a plastic plate that is roughly twice the width of the bug zapper. Paper will be easier to work with, but plastic will last longer.
Cover the bottom grill of the bug zapper with an all-purpose adhesive.
Place the plate on a table, and place the zapper on the plate. The weight of the zapper will be enough to make an effective bond between the plate and the adhesive on the zapper grill. Allow the adhesive to fully dry.
Hang the zapper on a ceiling hook. A kitchen would be the ideal place, because it is a room with food odors that attract bugs.
Remove and clean the plate on a regular basis to get rid of all the bug waste.
Ceiling hook kits are available at hardware stores. Ceiling hooks can be mounted by either screwing the hook directly into a stud, or by pushing a drywall anchor into the drywall, and screwing the hook into it.
