Bird mites (Dermanyssus gallinae) are small, parasitic pests that feed primarily on the blood of birds. While they prefer avian hosts, these mites can sometimes bite people when bird nests are nearby or after birds have left a nesting site. Though they don’t live or reproduce on humans, their bites can cause irritation and discomfort.
Bird mites are tiny arachnids that associate closely with birds and their nests. They are most active during spring and early summer. These mites can become a nuisance when they migrate from abandoned nests into homes or commercial buildings in search of new hosts.
Due to their small size and rapid movement, identifying bird mites can be challenging without the aid of professional assistance. Our technicians are trained to correctly identify and manage this pest, helping to protect your home or business from further infestation.
These traits make this species one of the more common parasites associated with birds and poultry environments.
Bird mites rely on birds for food and shelter, so their habits are closely tied to where birds nest, rest, and raise their young. Learning more about a bird mite's habitat, what they eat, and the rate of their reproduction helps explain why infestations can rapidly grow when nests are located near homes or businesses.
Bird mites prefer warm, moist areas located close to birds. They are common in bird nests, poultry houses, and roof spaces where birds have been roosting. These mites hide in cracks, crevices, and nesting materials until they can reach their host. In poultry settings, heavy activity can reduce egg-laying efficiency and may affect young, sick, or older birds.
When birds leave a nest, mites may spread into nearby structures in search of a meal. In some cases, they may bite people, though they cannot live on human hosts.
The bird mite diet consists of blood taken from birds. They feed at night and retreat to hidden areas during the day. When birds abandon a nest, mites may move inside homes or other structures and may bite people while searching for food. Their bites can cause itching or discomfort, and anyone with these symptoms should contact a healthcare professional for guidance.
The bird mite life cycle is short but highly productive. Under favorable conditions, the bird mites can develop from egg to adult in around seven days. Adult mites live for around 90 days, during which females can produce hundreds of eggs. This fast reproductive cycle allows infestations to grow quickly.
They stay close to birds and nesting areas, gathering in cracks, seams, and other tight spaces during the day. When a nest is disturbed or the birds leave, mites may spread to nearby rooms, vents, and wall voids in search of another host.
Managing bird mites starts with removing the source, such as active or abandoned bird nests. Once the nests are cleared, thoroughly cleaning and vacuuming the surrounding areas can help reduce the number of mites. Because these mites can hide in tiny cracks and reproduce quickly, professional treatment is recommended to help eliminate the issue at its source.
Preventing a bird mite infestation begins with keeping birds from nesting on or near your property. Once nests are no longer active, check and remove them from under eaves, gutters, or attic spaces—repair gaps in roofing, vents, or other areas where birds could enter.
DIY cleaning can offer short-term relief, but it’s best to contact our technicians for a professional inspection and treatment.
The most effective way to help manage bird mites involves a combination of nest removal, environmental cleaning, and targeted treatments performed by trained technicians. Our team can assess the situation, treat affected areas, and recommend steps to reduce future risks.
They usually come from bird nests located in or near homes and other structures, such as eaves, attics, or vents.
No. Bird mites cannot survive or reproduce on humans, but may bite when seeking a blood meal.
They are often found near windows, ceilings, or air vents near where birds nest.
Bird mites are not known to spread diseases to humans, but their bites can be irritating. Always consult a healthcare professional if you experience symptoms.
