Encasement is the quiet half of bed bug work. The treatment kills what's active; the encasements make sure the mattress and box spring stop being a hiding place you can't reach. Done at the right point in the job, they take two of the hardest pieces of furniture in the room out of the equation permanently.
A proper bed bug encasement is a sealed fabric cover that zips fully around a mattress or box spring, with a zipper end-stop designed so nothing can crawl out at the slider. Anything already living inside is trapped and dies there. Anything new that arrives has nowhere to go but the outside surface of the cover, where it's visible on a plain white fabric and reachable by treatment. That second part matters more than people expect — box springs in particular are mostly hollow, lined with stapled fabric and wood seams, and they're the most common place we find a population that survived a half-done job.
Encasements go on after treatment, not before. Covering an infested mattress first just seals the problem in where it can't be inspected, and the cover usually comes off again when someone decides to flip the bed. We install them as part of the treatment sequence, usually at the first service visit once the bed frame and surrounding area have been handled.
Upholstered chairs, recliners and sofas are harder. They aren't a simple rectangle, so true zippered encasement only works on cushions, and the frame itself has to be treated directly — seams, staple lines, the dust cover underneath, the recliner mechanism. If a sofa is heavily infested and the frame is already damaged, replacement is often the cheaper path, and we'll say so rather than sell you covers that won't solve it. For headboards, bed frames and nightstands, the answer is treatment and inspection, not encasement.
What changes the price is straightforward: how many sleeping surfaces there are, whether box springs are included, mattress sizes and depths, and whether we're covering one bedroom or an entire apartment where every room has a bed. Multi-unit buildings around Roseville, Eastpointe and Warren often need adjoining units checked at the same time, because a sealed mattress in one apartment doesn't help if the source is on the other side of a shared wall.
Ask whether the encasement is rated for bed bugs specifically, not just for allergens or waterproofing — the allergen covers sold cheaply have zippers bugs walk straight through. Ask about the zipper closure design. Ask how long the cover stays on: the answer should be at least a year, and in practice we recommend leaving them on indefinitely rather than pulling them off the moment the problem looks solved. And ask whether the cover tears, because thin vinyl splits at the corners within months and a torn encasement is worse than none, since it gives bugs a one-way entrance.
