Bed bugs are the one household pest that has almost nothing to do with how a home is kept. They do not come up from the yard, they are not drawn in by crumbs, and they are not a sign that anything went wrong. They arrive on things people carry. Florida moves an enormous number of visitors, seasonal residents, students and second-hand furniture around every year, and that traffic is the whole mechanism.
Because of that, the two skills that matter are knowing how they travel and knowing where to look. Both are unglamorous, and both work far better when the population is still small.
They move on objects, not on their own
The EPA is direct about it: “Bed bugs are great hitchhikers. They can move from an infested site to a new home by traveling on furniture, bedding, luggage, boxes and clothing” (US EPA, Protecting Your Home from Bed Bugs). The same page notes that although they typically feed every five to ten days, they are capable of surviving several months to a year without feeding.
That second detail is the one people underestimate. A sofa that has been sitting in a storage unit, a suitcase that spent the off-season in a closet, a box of books from a relative’s house that nobody opened for eight months. None of those are safe by virtue of time passing.
Do not diagnose this from bites
Almost everyone starts here, and it is the least reliable place to start. EPA guidance states that “Bites on the skin are a poor indicator of a bed bug infestation,” because the marks can look like bites from mosquitoes or chiggers, like a rash such as eczema or a fungal infection, or even like hives. Some people do not react to the bites at all (US EPA, How to Find Bed Bugs).
Misidentification also costs time. Carpet beetles get mistaken for bed bugs constantly, and EPA points out that a wrong call gives an actual infestation more room to spread through a house or hitch a ride to someone else’s.
The physical signs that mean something
EPA lists what to look for when you are changing bedding, cleaning, or staying somewhere away from home:
- Rusty or reddish stains on sheets or mattresses, caused by bed bugs being crushed
- Small dark spots, which are excrement, and which can bleed into fabric the way a marker would
- Eggs and eggshells, roughly a millimeter across, and the pale yellow skins nymphs shed as they grow
- Live bed bugs
The dark spotting is usually the first thing a careful person finds, and it tends to show up in lines or clusters along a seam rather than scattered at random.
Where to actually look
Around the bed, EPA points to the piping, seams and tags of the mattress and box spring, and to cracks in the bed frame and headboard. That is the short list, and in a low-level infestation it is often the whole list.
If a room is heavily infested, the search widens considerably. EPA names the seams of chairs and couches, the space between cushions, the folds of curtains, drawer joints, electrical receptacles and appliances, the area under loose wallpaper and wall hangings, the junction where wall meets ceiling, and even the head of a screw. The reason it goes that far is a matter of size: “Since bed bugs are only about the width of a credit card, they can squeeze into really small hiding spots. If a crack will hold a credit card, it could hide a bed bug.”
Behavior that tells you where to search next
A few points from EPA’s summary of bed bug habits change how you inspect a room:
- They will readily travel five to twenty feet from an established hiding place, called a harborage, to reach a host. A nightstand, a nearby armchair and the baseboard behind the headboard are all inside that radius.
- They are primarily active at night, but if hungry they will seek hosts in full daylight. Daytime activity does not rule them out.
- Feeding takes three to twelve minutes, which is why people almost never notice it happening.
- They can survive and stay active at temperatures as low as 46 degrees Fahrenheit, and they die when their body temperature reaches 113 degrees Fahrenheit. EPA adds that killing them with heat requires the room to be hotter still, so that sustained heat reaches them wherever they are hiding.
That last point is worth holding on to, because it explains why leaving a suitcase in a hot car or a closed Florida garage is not a method. The temperature that matters is the one reached inside the object, sustained, not the one on the dashboard.
Habits that keep them out
EPA’s prevention list is short and mostly behavioral:
- Check second-hand furniture, beds and couches for signs of infestation before bringing them into the house. Florida’s resale and curbside furniture market makes this the single highest-value habit on the list.
- Use a protective cover that encases the mattress and box spring, which removes many hiding places. EPA suggests buying a good quality encasement that resists tearing, notes that a light-colored cover makes bugs easier to see, and advises checking it regularly for holes.
- Reduce clutter, which reduces hiding places.
- Vacuum frequently, to pick up anything that made it in.
- Be careful with shared laundry facilities. EPA suggests transporting items in plastic bags, removing them from the dryer straight into a bag, and folding at home, noting that a dryer on high heat can kill bed bugs.
When traveling, the practical version is to inspect the luggage rack in a hotel room, keep bags off the bed and off upholstered furniture, and look at the mattress piping and the headboard area before unpacking. It takes about two minutes and it is the difference between finding a problem in someone else’s room and finding it in yours.
If you live in a multi-family building
Condos, apartments and duplexes make up a large share of Florida housing, and EPA has specific advice for isolating a unit: install door sweeps on the bottom of doors to discourage movement into hallways, and seal cracks and crevices around baseboards, light sockets and similar openings to discourage movement through wall voids. Those steps do not treat an infestation. They limit how easily one travels between units, which matters when the source is not yours to fix.
Why this one rarely stays a homeowner job
Nearly every other household pest gives you a fair chance of resolving it with cleaning, exclusion and patience. Bed bugs are harder for a specific structural reason: the hiding places are numerous, tiny and distributed across furniture, walls and fittings, and missing a small share of them lets the population rebuild. EPA’s own framing is that finding an infestation early, while it is still minor, is far less costly and far easier than dealing with the same infestation once it has spread.

Before anyone treats a room
Two things are worth doing first. Confirm the identification, ideally by keeping an actual specimen rather than a photograph. And write down where each sign was found, because that map is what an inspection builds on and it is far harder to reconstruct from memory a week later.
When comparing companies, ask each one to confirm license status and insurance coverage, ask how they will inspect rather than only how they will treat, ask what preparation is expected of you, and ask what happens on a follow-up visit. Bed bug work is rarely a single appointment, and how the follow-up is defined matters more than anything said on the first call. Homeowners and renters in the larger metro areas run into this most often, and our Miami area page and Tampa area page outline how matching works in those regions.
