How to use it

Set one cup under each leg of the bed, with the leg in the center well.
Pull the bed a few inches away from the wall and the nightstand, so the legs are the only way up.
Tuck the sheets and blanket in: nothing should hang down to the floor.
Keep the inside wall clean and dry: a slick wall is what holds a bug in the cup.
Check and clean the cups every week; tip them into a smooth plastic tub to see what they caught.

How many you need

One cup under each leg: a frame on four legs takes four, one with a center support takes six or more. These are XL cups, for square or wide legs and heavy furniture.

Count the cups for your home.

Extra-large one-piece cups, 7 by 4 inch opening

Wide bed posts that will not fit a standard cup usually fit this one: the opening measures 7 by 4 inches. Like the smaller version, it is molded in one piece with smooth inner walls. You can choose clear or white, and the box holds four, one for each leg of your bed.

An oblong opening helps with rectangular legs and posts that are longer than they are wide. Set the cups on a clean, level floor, lower each leg in, and look inside on a regular schedule. Rinse them out when they need it and put them straight back. No tools are involved.

How to set out the Zulu Supply XL Passive Interceptor Cups follows the EPA and Texas A&M's extension service: one cup under each leg, the bed pulled off the wall, a look every week.

This is general information about keeping bed bugs out of a bed, not pest control or medical advice. A licensed pest professional, your doctor and the maker's own instructions come first.

What the public sources say

Texas A&M AgriLife Extension, "What is a bed bug interceptor?". Explains that bed bugs climb slippery vertical walls poorly, puts a cup under each bed post with the bed off the walls and no bedding on the floor, counts at least 12 cups for a two-bedroom apartment, and cleans them at least once a month. Read October 30, 2026.
U.S. EPA, "Do-it-yourself Bed Bug Control". Says to set interceptors under each leg of infested furniture, move it a few inches off the walls with no linens touching the floor, check and clean the interceptors every week, keep inspecting at least every 7 days, and use covers that seal mattresses and box springs so bed bugs inside die.
