Bed Bug Pillow Encasements and Zippered Protectors

Standard, queen or king: check the tag on your pillow

A standard pillow is about 20 by 26 inches, a queen 20 by 30, a king 20 by 36. A cover one size too big folds over the zipper end and leaves a gap, and one size too small will not close.

Pillow covers zip on the short end and go into the wash with the sheets. Most come in packs of two or four, which is also how most beds use them.

14 covers on this shelf, out of 62 in the Bed Bug Blocker selection.

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, "Protecting Your Home from Bed Bugs". Calls bed bugs hitchhikers on luggage, furniture and clothing, says they can survive several months to a year without feeding, and advises a high quality encasement for the mattress and box spring, checked regularly for holes. Read October 30, 2026.
CDC, "About Bed Bugs". States that bed bugs are not known to spread disease, that bites can cause itching, loss of sleep and rarely allergic reactions, and that bed bugs travel in the seams and folds of luggage and clothes. Read October 30, 2026.
