Do Bed Bugs Live on Dogs?

Short answer: no, bed bugs do not live on dogs. Unlike fleas or lice, bed bugs are not adapted to cling to fur or stay on a moving host. They hide in nearby cracks, seams and furniture, feed briefly, then retreat. If your dog is scratching and you suspect bed bugs, the insects are almost certainly in the environment, not on your pet.

It’s frustrating when a beloved dog seems uncomfortable and you’re finding bites on people in the home. We’ll walk you through the science, what to check, and the safest, most effective way to clear an infestation. As heat-treatment specialists, ThermoPest focuses on evidence-led control that removes bed bugs in all life stages without leaving chemical residues.

What people believe vs reality

Belief: Bed bugs live in dog fur like fleas. Reality: Bed bugs lack claws to grip fur and prefer to hide in beds, sofas, skirting, and furniture joints.
Belief: Dog flea treatments will fix bed bugs. Reality: Flea products do not work on bed bugs or their eggs and may be unsafe if misused.
Belief: Pets bring bed bugs into the home on their bodies. Reality: Bed bugs hitchhike mainly on luggage, clothing, soft furnishings and pet bedding or crates — not on the pet itself.

Science-backed facts

Host preference: Bed bugs prefer human blood but will bite dogs if humans aren’t available.
Hiding behaviour: They live within a few metres of where people (and sometimes pets) rest, emerging at night to feed for minutes and then hiding again.
Egg resilience: Eggs are more resilient than nymphs or adults, which is why a single missed harbourage can restart a population.
Lethal heat: Sustained temperatures at the correct level kill all life stages; see what temperature kills bed bugs for the exact ranges and exposure times.

Common mistakes that prolong infestations

Treating for the wrong pest: Itching on a dog is often fleas or mites; always confirm before acting. If you’re unsure, learn how to check for bed bugs in sleeping and seating areas.
Overusing aerosols or foggers near pets: These rarely reach harbourages or eggs and can expose animals unnecessarily.
Moving beds, sofas or dog bedding room-to-room: This spreads bed bugs and makes control harder.
Discarding mattresses prematurely: You risk spreading bugs during removal and still leave harbourages behind.

Practical, pet-safe steps you can do now

Inspect: Check mattress seams, headboards, sofa frames, skirting gaps, and the dog’s bed seams/piping for spots, cast skins, and live insects.
Heat and contain soft items: Wash the dog’s bedding and soft toys at 60°C and tumble-dry on high for at least 30 minutes after full dryness.
Reduce clutter and isolate sleeping zones: Pull beds away from walls; keep dog beds a little separated from headboards and sofas.
Vacuum methodically: Focus on cracks, bed joints, sofa undersides and the dog-bed area. Empty the vacuum outside immediately.
Plan professional eradication: Bed bug eggs and inaccessible harbourages are why most DIY efforts stall.

Why heat treatment is the superior solution

Chemical resistance and hidden harbourages are the main reasons bed bug problems persist. Whole-room heat treatment addresses both.

Eliminates cold spots: Professional heaters circulate air to remove cold pockets in corners, under mattresses, and inside furniture, ensuring even penetration.
Sustained lethal temperature: Rooms are held at target temperatures long enough to kill eggs, nymphs and adults together, not just surface bugs.
Sensors and monitoring: Multiple wireless sensors confirm temperatures across the space and deep inside items, so no area is left undertreated.
All life stages killed: The combination of reach and duration means eggs—the usual cause of “reinfestation”—are neutralised in one programme.

ThermoPest expertise

ThermoPest specialises in professional bed bug heat treatment for homes and also delivers commercial heat treatment for hotels and landlords where pet-friendly policies and fast turnaround are essential. Our technicians use calibrated sensors, airflow management and thorough inspections to confirm complete coverage. Before we arrive, we’ll guide you through preparing your home for treatment so heat can reach every hiding place, including pet bedding and furniture.

Heat vs chemicals: why heat wins for homes with pets

No lingering residues: Once temperatures return to normal, rooms are safe to re-occupy as advised.
Fast resolution: A correctly run programme clears all life stages in a single day in most standard jobs.
Tough on eggs, gentle on homes: Heat penetrates fabrics and furniture where sprays struggle, especially around pet areas you want to keep chemical-free.

FAQ’S

Question: Can bed bugs live on dogs?

Answer: No. Bed bugs are not built to live on fur; they feed for minutes and hide in nearby cracks, seams and furniture. If your dog is itchy, the bugs are in the environment rather than on the pet itself. Tip: inspect the dog’s bed seams and the areas where people sleep first. In professional practice, we confirm by finding harbourages rather than relying on symptoms alone.

Question: Do bed bugs bite dogs and cause itching?

Answer: They can bite dogs, but they prefer human hosts. On dogs, bites may show as small, itchy welts, often mistaken for fleas or mites. Because eggs are resilient, untreated harbourages keep producing new nymphs that will continue to feed. Tip: rule out fleas with a fine-tooth comb and check sleeping areas carefully; if you confirm bed bugs, whole-room heat is the most reliable fix in practice.

Question: Could my dog bring bed bugs into the house?

Answer: It’s unlikely the insects ride on your dog’s body for long. Bed bugs hitchhike on luggage, blankets, second-hand furniture and pet bedding or crates after travel. That’s re‑introduction rather than “reinfestation” from the dog itself. Tip: after trips, heat-treat soft items in a hot tumble dryer for 30+ minutes at high heat; professionals routinely use heat to prevent cold spots where eggs could survive.

Question: What should I do with my dog’s bedding during a bed bug treatment?

Answer: Wash at 60°C and tumble-dry on high for at least 30 minutes after items are fully dry to ensure lethal temperatures reach the core. Place cleaned bedding into sealed bags until the room treatment is completed to avoid re-seeding. DIY steaming can help on seams but often misses insulated areas and eggs. Tip: follow the provider’s prep list so airflow and sensors can verify temperatures throughout in professional practice.

Question: How do I know the bed bugs are really gone if I have pets?

Answer: Confirmation comes from inspection and the absence of fresh signs after a full heat cycle, not simply from fewer bites. Because cold spots and missed eggs are the usual reason for recurrence, monitoring and careful checks over the following weeks are important. Tip: keep sleeping areas tidy and re-check seams and frames at 7–14 day intervals; professionals document temperatures and coverage during treatment to evidence eradication.
