What you get

Reusable: empty it and set it back.
Packs of 4, 8, 12.

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 standard cups; a square or wide leg needs an XL cup.

Count the cups for your home.

One-piece cups with a 4.25 inch opening

Any leg that fits a 4.25 inch opening will sit in this cup, whether it belongs to a bed, a couch or a chair. Measure your legs before you order. The cup is molded in one piece of sturdy plastic with smooth inner walls, so there are no joints to come apart.

Packs of 4, 8 and 12 come in black, clear or white. Clear lets you see a catch from the side without lifting the leg. Set each cup on a clean, level floor, lower the leg in, and make a look into the cups part of your weekly routine. No tools and no assembly are needed.

How to set out the Zulu Supply 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.
