You found one · the next few hours decide how bad this gets
You found a bed bug. What to do tonight.
First, breathe. Bed bugs are not known to spread disease, and a problem caught this early is very treatable. What turns one bug into a whole-home infestation is the panic move — sleeping on the couch, throwing out the mattress, setting off a bug bomb. Here is the calm version. Every step below is drawn straight from the EPA, the CDC and university extension programs, and cited at the bottom.
Do these tonight
-
Catch it — don’t just squash it
Trap the insect under a strip of clear packing tape, or photograph it as close as your camera will focus, and seal it in a bag or jar. You need a specimen because bites alone cannot confirm bed bugs — fleas, carpet beetles and other insects are mistaken for them constantly. A real sample is what lets an expert give you a yes or no. EPA · UMN Extension
-
Stay in your own bed — do not switch rooms
This is the one nobody expects. Moving to the sofa or a spare room does not leave the bed bugs behind; they follow the carbon dioxide you breathe and simply learn a second place to live. As Minnesota’s extension puts it plainly: moving your things from the room with bed bugs to another room “may spread the bed bugs.” Sleep where you were. UMN Extension
-
Bag your laundry, then heat it — don’t just wash it
Put the bedding and the clothes nearest the bed into sealed plastic bags. Run them through a clothes dryer on high heat for at least 30 minutes. It is the dryer’s heat, not the wash water, that kills bed bugs and their eggs. Keep anything you’ve heated sealed in a fresh bag until the room itself is treated. EPA · UMN Extension
-
Put traps under the bed legs
If you can get them tonight, slide interceptor cups under every bed and furniture leg and zip encasements over the mattress and box spring. Interceptors catch climbing bugs and tell you whether they’re still active; encasements trap any inside and make the mattress easy to check. Nothing open? A do-it-yourself interceptor is two nested plastic containers with a little talcum powder in the bottom. EPA
-
Start a written record now
Write down the date, the exact spot you found it, and keep every photo. The EPA’s own advice: “keep records through the whole process — note the dates and exact locations.” This is the paper trail a landlord, an exterminator or an insurer will ask for. Our evidence & expense log gives you a place to keep it. EPA
-
If you rent, tell your landlord — in writing
Notify your landlord today, in writing, and keep a dated copy. In most states, written notice is the exact step that starts the landlord’s legal clock and protects your rights later. The notice guide and letter generator handle the wording; your state’s page shows the deadline it triggers and who pays.
Do not do these — each one makes it worse
Ineffective & spreads it
No bug bombs or foggers
Total-release foggers “are not effective for controlling bed bugs, and we strongly recommend against using them.” The mist never reaches bugs tucked in cracks, and it scatters the survivors into other rooms and neighboring units. EPA · UMN Extension
Fire hazard
No rubbing alcohol, kerosene or gasoline
Soaking furniture in “rubbing alcohol, kerosene and gasoline could harm you and your family and can easily ignite.” House fires have been started exactly this way. EPA
Dangerous
No space heaters to “cook” the room
Trying to heat a room yourself with propane or thermostat heaters “does not work and is dangerous.” Whole-room heat is a job for a professional’s calibrated equipment. EPA
Spreads it & costs you
Don’t throw out the bed or furniture
“Do not throw away your furniture. Beds and other furniture can be treated for bed bugs.” Dragging an infested mattress through a building seeds bugs the whole way — and you’d be replacing things you never needed to. UMN Extension · EPA
Spreads it
Don’t flee to a friend or relative
Packing a bag and staying elsewhere is precisely how bed bugs reach the next home. If you truly must leave, heat-treat your clothes in a dryer first and carry them in a sealed bag. UMN Extension
Ineffective & risky
Don’t empty a can of store spray everywhere
Over-the-counter insecticides won’t clear an infestation, and blanket-spraying drives bugs deeper and exposes your household. Anything you do use must be EPA-registered and labeled for bed bugs indoors — never an outdoor product. CDC · UMN Extension
Then, over the next few days
Tonight is about not making it worse. Getting rid of them is the next job — and it is very doable with the right plan.
- Confirm it really is a bed bug. Take your specimen to a county extension office or a licensed pest professional — verify their license for bed bug work before anyone treats your home.
- Choose a treatment that actually works. Heat, steam and targeted, labeled insecticides each have a role; foggers and kitchen-cupboard remedies do not. See heat & cold and what actually works.
- Don’t call it over too soon. A quiet week after treatment is not proof — eggs keep hatching. What counts as truly cleared is on did it work?
