Product Overview

Protect-a-bed Bed Bug Box Spring Encasements are the pest control and hotel industry's choice for protecting box springs against bed bugs, allergens, dust mites, dirt and liquids. These high-quality protectors are trusted by hotels world-wide and have been certified by an entomology laboratory to be 100% bed bug proof. Any bed bugs you seal up in the bed bug boxspring encasement cannot escape or bite through the encasement, and will eventually die. This means you can save your boxspring without throwing it out!

Not for use on mattresses. For mattress protection, please purchase Protect-a-bed Bed Bug Mattress encasements.

Please note: The Protect-A-Bed California King size box spring encasement is actually a set that includes two separate encasements, as a California King mattress always rests on two individual box springs.

Why use a box spring encasement for bed bug control?
Bed Bug boxspring encasements and mattress encasements are a recommended addition to any bed bug treatment program. You will still need to treat infested areas of the bedrooms. However, because the #1 breeding ground for bed bugs is the mattress and boxspring, you can now just spray and then zip up these critical areas which will eliminate a large part of the infestation. In addition, this can save an infested boxspring so you don't have to throw it out and buy a replacement. Any eggs and/or bed bugs trapped in the encasement will eventually die. Boxspring encasements and mattress encasements are also nice because they provide very few if any places for bed bugs to hide and harbor (compare that with all of the folds, seams, nooks and crannies of a mattress and box spring), and they are clean and white making future investigation and treatment easy. Also consider that if you should find bed bugs on your mattress again at some point in the future, treatment would be as easy as taking off the mattress encasement and washing it in warm water. Again, the key harborage areas for bed bugs would be protected, and so would your mattress investment.

We recommend spraying an infested boxspring with bed bug control products first before encasing it and then keeping the encasement intact for at least 12 months (bed bugs can live a very long time without a blood meal). The bed bugs and eggs inside will die, and the box spring will be protected from further infestation.

Can you use the Protect-A-Bed Box Spring Covers on mattresses?

Why can't you use this cover on a mattress? What are the actual dimensions of the Cal King box spring covers?


You can not use the California King Box Spring Cover on the mattress for two reasons, 1. the material is not durable enough to be used (slept on) daily like the mattress encasement, which is made of thicker more durable, bedbug bite proof fabric and 2.  the Cal King box spring covers are actually a set of two covers, one for each box spring (California King beds have two seperate boxsprings). The dimensions of each box spring encasement are 36x84x9.

Do you have a box spring cover to fit 36"x83"x7.5"
We do carry the California King Box Spring Covers which measure 36 x 84 x 9 which would fit the box spring according to the measurements you provided. The 9 inch deep box spring is standard and the manufacturer does not make smaller box spring covers.
