Frequently asked questions

What is a mattress encasement and how does it differ from a mattress protector?

A mattress encasement fully zips around the entire mattress, covering all six sides, while a protector typically covers only the top and sides. Encasements are designed to seal out bed bugs and dust mites completely, making them ideal for pest control.

Can a mattress encasement kill bed bugs?

An encasement can trap bed bugs inside, eventually killing them by starvation, as they cannot escape to feed. It also prevents new bugs from entering the mattress. For active infestations, combine with other treatments.

How do I choose the right mattress encasement for bed bugs?

Look for a design with a secure zipper that has a flap or cover to block the zipper track. Also check for certifications like CertiPUR-US or OEKO-TEX, and consider material breathability for comfort.

Will a mattress encasement change the feel of my mattress?

Some encasements can add a slight layer that may affect feel, especially if they are waterproof. Look for stretchable or cotton-topped options for minimal change. Owner reviews often mention this.

How often should I replace a mattress encasement?

Typically every 3-5 years, depending on wear. Replace sooner if the zipper breaks, fabric tears, or if you see signs of bed bugs. Follow manufacturer care instructions.

The verdict

For best overall bed bug protection, choose the Protect-A-Bed AllerZip Smooth Mattress Encasement with its secure BugLock zipper. For budget buyers, the SafeRest Premium offers excellent value. Hot sleepers should consider the PlushDeluxe Premium for its cooling properties.
