The covers fully encase the mattress and the box spring. They take approximately five minutes to install. If the mattress is currently infested it is recommended that you first vacuum the mattress or box spring and then simply slip the cover over the mattress or box spring and zip closed. After installing it is recommended that you leave the encasement in place without laundering it to ensure that all bedbugs that may have been present die off. Consider the encasement as now part of the mattress.

 

The fit of the encasement is extremely important. If the encasement is too small you risk a tear and a way for bed bugs to escape. If the encasement is too large there will be folds in the material where bed bugs can hide. It is also recommended you use duct tape to cover the sharp edges of the box spring so that you protect the box spring encasements from tears.
