Follow these easy instructions to make your own bed bug trap and put an end to guessing what might be biting you!

How the Bed Bug Trap Works

Place a thermos with dry ice on top of a glass bowl sitting inside a litter box. Bed bugs are attracted to the CO2 you give off when sleeping, which dry produces as it warms. Being heavier than air, the CO2 drops down into the box and overfills into the room – it’s like a loud dinner bell!

The bugs climb up the box, fall inside, and can’t get out. The outer cloth helps them climb up and drop into the box, but once in, the powder and plastic sides are too slippery to escape, and the bugs become trapped.

It takes less than an hour to make, and you can do it with products from your local dollar store. You’ll need a plastic cat litter box, glue, white paint, baby powder (avoid powder made with cornstarch), scissors, cloth, foam brush, dry ice, insulated thermos with spout on top, and a small round glass bowl.

The local dollar store had everything I needed ($1 each) except for the dry ice, which I purchased from Walmart for $2.00.

⇒ The goal here is to catch and confirm an infestation. If you don’t want to do this project yourself, you can buy an 8 pack of bed bug traps from Amazon.
