Bed bugs in an apartment are a fixable problem, but they require fast action because these insects spread between units through wall voids, electrical outlets, and plumbing chases. Unlike a single-family home, an apartment building means your infestation may not have started with you, and getting rid of it often depends on your landlord and neighbors cooperating with treatment.
How to Confirm You Have Bed Bugs
Bites alone are unreliable. The EPA notes that bed bug bites look identical to mosquito bites, chigger bites, eczema, and hives. Some people never react to bites at all. So if you’re waking up with itchy welts but haven’t found any other evidence, you need to look harder before assuming bed bugs are the cause.
The physical signs are much more telling. Look for rusty or reddish smears on your sheets (from bugs being crushed while feeding), tiny dark spots about the size of a pen tip that bleed into fabric like a marker (bed bug excrement), and pale yellow shed skins or eggs roughly 1mm long. Adults void partially digested blood about 20% of the time while still feeding, which is what produces those distinctive stains. Check mattress seams, the crevices of your bed frame, behind your headboard, and along baseboards within a few feet of where you sleep. Bed bugs stay close to their food source, so the heaviest evidence is almost always near the bed.
How Bed Bugs Spread Between Units
Bed bugs can’t fly or jump, but they’re persistent crawlers. In apartment buildings, they travel through electrical conduits, plumbing chases, shared walls and ceilings, and common hallways. Any crack wide enough for a credit card edge is wide enough for a bed bug. They also hitchhike on laundry, furniture, and bags moved through shared spaces.
This is why treating only your unit often fails. The EPA recommends that landlords evaluate all adjacent units (both sides, above, and below) when an infestation is reported. Some pest control researchers go further, recommending treatment of every adjacent unit to improve the odds of success. If your building treats your apartment but ignores the unit next door, bugs can simply migrate back through the walls once treatment ends.
Who Pays for Treatment
Laws vary by state and city, but the trend over the past decade has been toward placing responsibility on the landlord. New York City provides one of the clearest examples: bed bugs are classified as a Class B (hazardous) violation, and building owners are legally required to eradicate them within 30 days. Landlords must also provide tenants with a written disclosure of any bed bug infestations in the building over the past year.
Even in places without bed bug-specific laws, most landlords carry a general obligation to maintain habitable conditions. In practice, this means pest control for infestations that aren’t clearly caused by a specific tenant’s actions. If your landlord refuses to act, most cities allow you to file a complaint with your local housing or health department. In New York, for instance, you can report the issue online or by calling 311.
Document everything. Take photos of bugs, stains, and bites. Save written communications with your landlord. This record matters if the situation escalates to a housing complaint or lease dispute.
What to Do Right Away
While you wait for professional treatment, a few immediate steps can slow the infestation and protect your sleep:
- Pull your bed away from the wall. Even a few inches reduces the number of pathways bugs use to reach you.
- Run clothes and bedding through a hot dryer for at least 20 minutes. A dryer on high kills all life stages of bed bugs, including eggs, within 30 minutes. Once items come out, seal them in plastic bags so bugs can’t reinfest them.
- Vacuum daily with a bagged vacuum. After each session, seal the bag inside a plastic garbage bag and dispose of it in an outdoor trash can. Check the hose and brush attachments for stragglers.
- Eliminate clutter, especially around the bed. Fewer hiding spots means fewer places bugs can avoid treatment. Don’t store anything under the bed.
Equally important is what not to do. Don’t throw away your furniture. Replacing a mattress doesn’t solve the problem if bugs are living in your walls or bed frame, and dragging infested furniture through the building spreads them to other units. Don’t use bug bombs or foggers. These push bed bugs deeper into wall voids and crevices, making professional treatment harder. Don’t spray pesticides on your mattress or yourself unless the product is specifically labeled for that use.
How Professional Treatment Works
Most apartment bed bug treatments use either chemical applications, heat treatment, or a combination. Heat treatment raises the room temperature until every surface reaches the thermal death point. Bed bugs die after 90 minutes of constant exposure to 113°F, or within 20 minutes at 118°F. Eggs are hardier and require 118°F sustained for 90 minutes to reach full mortality. Professional heat treatments typically maintain lethal temperatures for at least 60 minutes after every sensor in the room hits the target, which is why treatments can take several hours.
Your pest control company or landlord will likely ask you to prepare the apartment before treatment. This usually involves washing and heat-drying all fabrics, clearing items away from walls, emptying closets in the affected rooms, and sealing treated items in bags. Follow these instructions closely. Poor preparation is one of the most common reasons treatments fail and need to be repeated.
Preventing Reinfestation
After treatment, your biggest ally is a mattress encasement. These are specially designed sealed covers that trap any surviving bugs inside (where they eventually starve) and eliminate the seams, crevices, and folds that make mattresses such ideal hiding spots. Install one on both your mattress and box spring, and leave them on permanently. Fitted sheets go over the encasement and get washed normally, but the encasement itself stays put.
Not all encasements work equally well. Effective ones need bite-proof fabric, a zipper with teeth small enough to block immature bugs, and a complete seal at the zipper’s end stop with no gaps. Chemically treated mattress covers are not recommended over well-sealed encasements. Before installing, scrub mattress seams with a stiff brush and wipe or vacuum away any visible bugs and eggs. Check your bed frame for sharp edges or bolt heads that could tear the encasement, and cover them with adhesive felt pads.
Seal the entry points bugs use to travel between units. Caulk cracks along baseboards, around electrical outlets, and where pipes enter through walls. This won’t guarantee bugs can’t get in, but it blocks the easiest routes. Bed bug interceptors, small dish-like traps placed under each bed leg, serve as both a monitoring tool and a barrier. If bugs are trying to climb up to your bed, you’ll find them trapped in the interceptors, which tells you whether the problem is truly resolved or still active.
Continue vacuuming regularly for several weeks after treatment, and inspect your mattress encasement and bed frame weekly. Bed bug eggs can hatch up to two weeks after being laid, so a unit that looks clear immediately after treatment may show signs of activity again if any eggs survived. Catching a small resurgence early, before it becomes a full reinfestation, makes retreatment far simpler.
