Bed bugs are small, wingless insects that commonly infest homes, feeding on the blood of warm-blooded animals. Humans are their primary and preferred hosts. The role animals play in bed bug transfer is often misunderstood, as their interaction is more complex than simply hosting them.
Why Animals Aren’t Primary Hosts
Bed bugs do not typically live on animals in the same way fleas or ticks do. They prefer human blood, attracted by body heat and carbon dioxide, which helps them locate hosts.
Their physical characteristics are not well-suited for navigating dense fur or feathers. Their flat bodies and leg structures make it difficult for them to move through and reside within an animal’s coat for extended periods. Unlike other parasites, bed bugs do not embed themselves in an animal’s skin. They prefer to hide in cracks and crevices near their feeding source, emerging only briefly to take a blood meal before retreating. Animals are therefore not a sustainable long-term habitat for bed bugs.
How Animals Can Transport Bed Bugs
While bed bugs do not infest animals, pets can unintentionally transport these pests. Known as “hitchhiking insects,” bed bugs can temporarily cling to an animal’s fur or bedding if it passes through an infested area. This passive transfer means the animal acts as a temporary carrier, not a host for a sustained infestation.
This might occur if a pet visits an infested home, shelter, or veterinary clinic. Bed bugs might briefly attach to a pet’s collar, carrier, or bedding, which then allows them to be carried to a new location. It is uncommon for pets to pick up bed bugs outdoors, as these pests rarely survive for long outside and prefer indoor environments.
Protecting Your Home and Pets
Protecting your home and pets from bed bugs involves proactive measures. Regularly inspecting your home, especially pet bedding and furniture, can help identify potential issues early. Washing pet bedding and toys in hot water and drying them on the highest heat setting is an effective way to eliminate any bed bugs or eggs that might be present.
When traveling with pets, keeping their carriers, bedding, and luggage away from sleeping areas in hotels can prevent bed bugs from hitchhiking. If a bed bug infestation is suspected, the focus should be on treating the environment rather than the pet directly. Products designed for fleas or ticks are not effective against bed bugs. For effective eradication, consult professional pest control services, and pets should typically be removed from the premises during chemical treatments.
