What you get

Top: cotton top.
Closure: zipper with a closed end.
Covers all six sides of the mattress or box spring.

How to use it

Measure the mattress from the bottom seam to the top, pillow-top included.
Zip the cover shut all round, and close the end of the zipper the way the maker shows.
Leave it on: bed bugs zipped inside die there in time.
Check the cover for holes and tears when you change the sheets.
Pair it with interceptor cups: a cover does not stop a bug from climbing onto the bed.

Will it fit?

Sizes: Twin, Twin XL, Full, Queen, King. The maker cuts it for 6-16" deep mattresses.

Find the cover for your bed size and depth.

All-cotton encasement in three depths

All-cotton fabric faces your sheets here, woven with a high thread count, and the maker gives its pore size as 10 microns or less. The maker says that tight weave is what keeps dust mites from passing through. A quiet zipper closes the cover around your mattress and finishes at a sealed end.

Pick a depth of 8, 12 or 16 inches. The Queen at 12 inches fits mattresses 10 to 12 inches deep, so measure before you choose. Colors include white, gray and blue, depending on size. The maker treats the fabric with Microban to curb odor, and you can machine wash it and tumble dry low.

How to use the FAUNNA Cotton Mattress Encasement follows the EPA and the University of Kentucky: zip it shut, leave it on for a year, and stand the bed legs in cups.

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

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. Read October 30, 2026.
University of Kentucky Entomology, ENTFACT-636 "Bed Bugs". Says bed bugs zipped inside an encasement eventually die, that an encasement does not stop a bug from climbing onto the bed, that a trap under each leg with the bed pulled off the wall makes the bed an island, and that a dryer at medium-to-high heat for 10 to 20 minutes kills all life stages.
