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

How the Trap Works

We are going to place a thermos with dry ice on top of a glass bowl sitting inside a litter box. Bed bugs zero in on the CO2 you give off when sleeping which is exactly what dry ice gives off as it warms. Being heaver 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 outside cloth helps them climb up and drop into the box but once in, the powder and plastic sides prove too slippery to escape and they 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 small round glass bowl.

Note, I already had some products, but when I went to the dollar store, I found they had everything I needed ($1 each) except for the dry ice which I purchased from my local grocer 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 a 4 pack of early detection glue traps from Amazon.
