Finding a tick in your bed is unsettling, but a single tick usually got there by hitching a ride on you, a family member, or a pet. It doesn’t necessarily mean you have an infestation. Your immediate priorities are removing the tick safely, checking yourself and pets for bites, and cleaning your bedding to kill any ticks you might have missed.
What to Do Right Now
If the tick is crawling freely on your sheets, pick it up with a piece of tape or fine-tipped tweezers and flush it down the toilet, or seal it in a ziplock bag. If you find it attached to your skin, grasp it as close to the skin surface as possible with fine-tipped tweezers and pull straight out with steady, even pressure. Don’t twist, and don’t try to smother it with petroleum jelly, nail polish, or a match. These old remedies don’t work and can actually cause the tick to release more saliva into the bite. Once it’s removed, wash the area with soap and warm water.
If the tick’s mouthparts break off and stay in your skin, don’t panic. Once separated from the tick’s body, the mouthparts can no longer transmit disease-causing bacteria. Your skin will push them out over time, similar to a splinter. If you accidentally crush the tick during removal, clean the area thoroughly with soap and water or rubbing alcohol.
Strip and Heat-Treat Your Bedding
Pull all sheets, pillowcases, and blankets off the bed. The fastest way to kill ticks is dry heat: toss everything directly into the dryer on high for at least 6 minutes. That’s enough to kill both blacklegged ticks (deer ticks) and dog ticks. If you want to wash your bedding first, you’ll need a longer drying cycle, up to 50 minutes on high heat, because ticks can survive a wash cycle, even in hot water. Inspect your mattress seams and pillows visually before remaking the bed.
Check Yourself, Your Family, and Your Pets
A tick found in bed likely crawled off someone or something before it had a chance to attach, or it detached after feeding. Do a full-body check on yourself and anyone who slept in that bed. Ticks favor warm, hidden spots: behind the ears, along the hairline, in the armpits, behind the knees, around the waistband, and in the groin area. On children, also check the scalp carefully.
If you have dogs, run your fingers through their fur slowly, feeling for small bumps. Pay close attention to the collar area, between the toes, and under the front legs. Cats can also carry ticks indoors, though it’s less common.
Is It Actually a Tick?
Ticks and bed bugs are roughly the same size when unfed (3 to 5 mm), so people sometimes confuse them. The easiest way to tell them apart is to count the legs. Ticks are arachnids with 8 legs and no antennae. Bed bugs are insects with 6 legs and short, visible antennae. Shape matters too: an unfed tick looks like a domed teardrop, while a bed bug is flat and oval, like a lentil.
If the bug you found was engorged (swollen with blood), the color helps. A fed tick balloons to pea-sized and turns grey-blue. A fed bed bug stays smaller, rounds out slightly, and turns deep red. Bed bugs also leave a different pattern of evidence: rows of small bites and tiny dark spots (fecal stains) on sheets. A single tick with no other signs points to a one-time hitchhiker, not an infestation.
Among common tick species, a few features help with identification. Blacklegged ticks (deer ticks) are small and dark, roughly the size of a watermelon seed when unfed. Females have a reddish-brown body with a black shield behind the head. American dog ticks are larger with mottled brown and white markings. Lone star ticks are easy to spot: the adult female has a single white dot in the center of her back.
Could Ticks Be Breeding in Your Home?
Most tick species cannot survive or reproduce indoors. Deer ticks, lone star ticks, and American dog ticks all need outdoor humidity and vegetation to complete their life cycles. If one of these species ended up in your bed, it came from outside and won’t establish a population in your house.
The one exception is the brown dog tick. This species thrives in warm, dry indoor environments and is the only common North American tick that can infest a home. An engorged female drops off her host dog, crawls upward into cracks and crevices (baseboards, furniture joints, electrical outlets, curtains), and lays 1,000 to 3,000 eggs. Under warm conditions, the full life cycle can complete in about 63 days, and heavy infestations produce ticks emerging from furniture and walls in large numbers.
If you’re finding multiple ticks indoors over several days, especially small reddish-brown ticks near areas where your dog sleeps, you may be dealing with a brown dog tick infestation. That situation typically requires professional pest control along with treating your dog.
Disease Risk and What to Watch For
If you were bitten, your disease risk depends on two things: the species of tick and how long it was attached. Lyme disease, the most common tick-borne illness in the U.S., requires a blacklegged tick to be attached and feeding for at least 24 to 48 hours before the bacteria can migrate from the tick’s gut to its salivary glands and into your body. A tick that was crawling on your sheets and never embedded, or one you removed within a few hours, carries very low risk for Lyme.
Other diseases have different transmission windows. Some pathogens, like the virus that causes Powassan disease, can transfer much faster, though these infections are far less common.
After a bite, monitor yourself for 30 days. Early Lyme symptoms typically appear within 3 to 30 days and include a spreading rash (often in a bull’s-eye pattern, though not always), fever, headache, fatigue, muscle aches, and joint stiffness. If untreated, more serious symptoms can develop within 3 to 10 weeks, affecting the joints, heart, or nervous system. Stage 3 symptoms can appear 2 to 12 months after the bite. Early treatment is straightforward and highly effective, so noticing symptoms early matters.
Preventing Ticks From Reaching Your Bed
The tick almost certainly rode in on a person or pet. Cutting off that pathway is the most effective prevention. After spending time outdoors in wooded or grassy areas, do a tick check before getting into bed. Toss your worn clothes directly into the dryer on high for 6 minutes rather than into a hamper where a tick can crawl out overnight.
For dogs, consistent tick prevention is the single most important step. Talk to your vet about topical or oral tick preventatives. You can also treat your dog’s bedding, blankets, and sleeping areas with a permethrin-based fabric spray, which remains effective against ticks for about 6 weeks. Apply it well before bedtime so the fabric dries completely. Permethrin is safe for dogs but toxic to cats while still wet. Once the treated fabric is fully dry, it’s safe around cats.
If your pet sleeps in your bed regularly and you’ve been finding ticks, consider giving them a designated sleeping spot with treated bedding until you’re confident the tick exposure is under control. Keeping grass trimmed short and clearing leaf litter near your home also reduces the number of ticks in your yard that can latch onto pets or clothing in the first place.
