Our Economy Bed Bug Protection Kit effectively prevents and eliminates bed bug infestations by the most economical means. By completely encasing the mattress on all sides with a barrier that bed bugs cannot get through, your bed is protected. By covering your mattress, box springs and pillows with our barrier encasements, any bed bugs that are already in will stay in, while bed bugs that are not already infested, will remain out. Since you need to encase your mattress at least 1 year to ensure all bed bugs, eggs, and larvae are dead, all our vinyl products are made of 6 gauge heavy duty vinyl which is built to last. Out economy kits come with one vinyl mattress encasement, one vinyl box spring encasement, and two pillow covers.
