Can Bed Bugs Feed on Pets?

Bed bugs, those tiny nocturnal pests that infest homes and feed on blood, often raise concerns for pet owners. In this article, we will delve into the question of whether bed bugs can feed on pets and provide insights into this matter.

The Natural Host Preference of Bed Bugs

Bed bugs, scientifically known as Cimex lectularius, are highly specialized in their choice of hosts. Their primary preference is for humans. They are attracted to the carbon dioxide we exhale, our body heat, and the specific scents and chemical compounds we emit. This makes human blood their preferred source of nourishment.

Occasional Pet Biting

While bed bugs are naturally inclined to feed on humans, there are cases where they may bite pets. These instances are rare and typically occur when bed bugs cannot find a human host. In such situations, they may feed on pets as a last resort. However, it’s important to note that the scent and blood chemistry of pets are not as appealing to bed bugs as human blood.

The Limited Feeding Experience on Pets

When bed bugs do feed on pets, they are less likely to feed to their full satisfaction. The unique chemistry of pet blood is not as suited to bed bug feeding, and as a result, the insects may not obtain a full blood meal.

Preventive Measures

To protect your pets from potential bed bug feeding, it is crucial to take preventive measures within your home:

  1. Regular Home Inspection: Conduct routine inspections for signs of bed bug infestations in your home. Look for small reddish-brown bugs, tiny white eggs, or small black fecal spots.
  2. Maintain Clean Pet Bedding: Keep your pet’s bedding clean and launder it regularly. Bed bugs are less likely to infest areas that are frequently disturbed and cleaned.
  3. Frequent Vacuuming: Pay special attention to areas where your pet rests or sleeps when vacuuming your home. This can help reduce the likelihood of bed bugs taking an interest in your pets.
  4. Professional Pest Control: If you suspect a bed bug infestation, contact a professional pest control service promptly to address the issue and prevent further infestation.


While bed bugs can occasionally bite pets in exceptional circumstances, they are not naturally inclined to do so. Humans remain their preferred hosts due to the unique scents and warmth they emit. By understanding the feeding habits of bed bugs and taking the preventive measures outlined in this article, you can significantly reduce the risk of your pets being bitten by these pests. Regular inspections and prompt action are key to keeping both your pets and your family safe from potential bed bug feeding.
