Protect-A-Bed Box Spring Encasement - King
  • Alternate Image 1

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

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.

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.

    5 of 5 stars  Works on My Split Queen Box Springs
    By Susan on 10/29/2010
    Verified Purchase

    I found these also work great on my split queen box springs in my guest room. I simply tucked the extra width to the inside. They seem fairly substantial and even come with a few pads for any rough edges on the bed frame. I am now ordering another pair to put on my king box springs.

    5 of 5 stars  Protect a bed box spring cover king
    By Nancy in DE on 07/04/2012
    Verified Purchase

    Received in record time. Purchased for daughter who was being bitten every night by bed bugs. After locating their origin in the box spring, copious spraying and applying this cover, she can now sleep again. One note, do not try to slide this off of the bedframe alone, she did and ripped the corner. Duct tape has fixed the rip and all is well. We were not looking forward to the enormous expense of an exterminator and this seems to have solved the problem with minimal cost. Thank you

    5 of 5 stars  Does it work?
    By Skip in Yuma, AZ on 07/22/2010

    We live in a high bug area. Just purchased a new bed set and didn't want to worry about bugs in bed with us. The cover is very easy to install. Seals the entire mattress, top and box springs. Worth the money if you want to protect an investment like this.

    This is a must if you buy the mattress cover. Why not the box spring cover, too? I will be buying again. Fast free delivery is a plus.

    It's so good to have my fiancé back in our bed. Our king size bed and pillows are completely covered with protect-a-bed encasements, and he hasn't been bitten at all since he came back to our bed! This makes ME very happy too!

QI have a king bed with two twin box springs, should I get twin box spring encasements or the king encasement?
What are twin box spring and king box spring encasement measurements? Thanks

AYou should get the King box spring encasements. The king box spring encasement includes two encasements measuring 38x80x9 each. The regular twin size (38x74x9) will be too short.
