Can Dogs Get Bed Bugs?

Worried your dog might be bringing bed bugs into the house? You’re not alone. As pest specialists, we’re asked this every week. The short answer is: bed bugs do not live on dogs like fleas do, but they can bite pets and may hitchhike on pet bedding or carriers. The real problem is almost always in the room’s furniture and cracks, not in your dog’s fur.

ThermoPest are heat-treatment experts. We use whole-room heat to remove bed bugs safely and thoroughly, without chemical residues around your pets. If you’re comparing options, understanding how bed bugs behave around animals will help you choose the right solution first time.

What people believe vs reality

Belief: Bed bugs live in dog fur. Reality: Bed bugs are flat, slow insects that hide in furniture, skirting boards, mattresses, and fabric seams. They don’t have the claws to cling to fur for long like fleas or lice, and they avoid light and movement.
Belief: Treating the dog will clear the infestation. Reality: Even if your dog was bitten, the infestation is in the room. Treating the pet alone won’t remove eggs hidden deep in furniture joints.
Belief: Moving the dog’s bed stops the spread. Reality: Moving items can transport bugs and eggs to new rooms if not sealed and heat-treated first.

Science-backed facts about dogs and bed bugs

Bed bugs prefer human blood but will feed on dogs (and other animals) when hungry.
They track hosts by warmth and carbon dioxide, feed for 5–10 minutes, then return to harbourages near the bed or sofa.
They lay eggs in cracks and fabric seams, not on the animal. Eggs are surprisingly resilient to many household sprays.
Lethal heat must reach the insect’s core; see what temperature kills bed bugs for the science we apply on every job.

Common mistakes that make things worse

Using flea products or pet shampoos to fix bed bugs — these target different pests and won’t reach hidden eggs and nymphs in furniture.
Setting off foggers or sprays in occupied rooms — these often push bugs deeper into cracks and leave cold spots untouched.
Moving the dog’s bed, blankets, or crate between rooms without sealing or heat-treating them first.
Discarding mattresses or dog beds too soon — this can spread bugs during removal and is usually unnecessary with proper heat treatment.

Practical steps you can do safely

Bag your dog’s fabric items (bed covers, blankets, soft toys) before moving them. Tumble dry on high (ideally 60°C) for 30–60 minutes; wash afterwards if labels allow.
Vacuum slowly around pet sleeping areas, mattress seams, sofa joints, and skirting boards. Empty the vacuum outside immediately.
Use simple interceptors under bed/sofa legs to help detect activity. Combine with regular visual checks of seams and labels.
Avoid spraying pet bedding with household insecticides. If your dog has skin irritation, speak with your vet.
If you plan a professional treatment, review preparing your home for treatment so nothing shelters bugs from the heat.
After a professional visit, use traps and visual checks to monitor your property after treatment and confirm eradication.

Why heat treatment is the superior solution for homes with pets

Chemicals struggle with hidden eggs and resistant strains. Whole-room heat, when delivered correctly, overcomes both problems and leaves no residues.

No cold spots: We move and space items so heated air reaches deep into sofas, dog beds, and furniture joints where bugs shelter.
Sustained lethal temperature: Room air is brought to roughly 56–60°C and contents are held so that all items reach lethal thresholds for long enough to kill eggs, nymphs, and adults.
Sensors and monitoring: We place multiple probes in “hard-to-heat” locations and log temperatures continuously to prove every zone reaches target ranges.
All life stages killed: Unlike many sprays, correctly applied heat inactivates eggs as well as mobile stages in a single programme.

If you’re comparing options, our professional bed bug heat treatment is designed for occupied homes and pet owners. You can also see exactly how we deliver results in our bed bug heat treatment process, including safety steps for pets and belongings.

ThermoPest heat expertise

We handle both domestic bedrooms and lounges, and larger sites where pets may visit or stay. For multi-room properties, guest accommodation, HMOs, or managed portfolios, we offer commercial heat treatment for hotels and landlords with discreet scheduling and documentation.

Our technicians plan the room layout, identify potential cold spots, and verify temperatures with calibrated sensors. We combine careful preparation with post-treatment checks so you can return pets once the space has cooled and been ventilated.

FAQ’S

Question: Can dogs carry bed bugs into the house?

Answer: Dogs don’t host bed bugs like fleas, but bugs can hitchhike on items your dog uses — blankets, soft beds, carriers and even the underside of fabric leads. The infestation itself lives in furniture and cracks, not on the animal. Bag pet bedding before moving it and tumble-dry on high heat to break any hitchhiking cycle. In professional practice, we always heat-treat or isolate pet items to avoid re-introduction between rooms.

Question: Do bed bugs live on dogs like fleas do?

Answer: No. Bed bugs feed briefly and then hide back in harbourages such as mattress seams, sofa frames and skirting boards. They lack the claws and body shape to live in fur long-term; that’s why treating the dog alone doesn’t remove the infestation. Focus on room-level eradication and keep your vet involved if you suspect fleas or skin irritation. In professional practice, room treatments target all life stages where they actually live.

Question: How can I tell if bed bugs are biting my dog?

Answer: Bite marks on pets are non-specific and can resemble allergy or flea bites. Instead, inspect where your dog sleeps: check seams of pet beds, nearby skirting boards, and sofa joints for black spotting, cast skins, or live insects. Use bed/sofa leg interceptors and a torch to confirm activity. In professional practice, we rely on evidence-based inspection rather than symptoms alone.

Question: Is heat treatment safe for dogs, and when can they return home?

Answer: Pets must be out of the treatment area while we heat the rooms to lethal ranges (room air typically 56–60°C). After cooling and ventilation, there are no chemical residues, so pets can return safely. Remove bowls, food, and medications beforehand, and flag heat-sensitive items during preparation. In professional practice, technicians confirm safe temperatures and ventilation before re-entry.

Question: Why don’t DIY sprays or foggers fix bed bugs in pet areas?

Answer: Sprays and foggers often leave cold spots and rarely penetrate deeply into sofa frames, bed joints, and thick pet bedding. Eggs are more resilient than adults, so surviving pockets lead to a quick rebound that feels like “re-infestation” but is usually incomplete control. A safer, more reliable approach is thorough vacuuming and hot laundering, followed by a professionally controlled heat treatment. In professional practice, we verify lethal temperatures with sensors so no refuges remain.
