These tiny, flightless parasites are closely related to bed bugs and share similar feeding habits. They typically infest the nests of birds, particularly swallows and other cliff-dwelling species. While their primary hosts are birds, they can bite humans if their usual food source is unavailable, such as when a bird’s nest is abandoned or removed. The bites often cause itchy red welts, similar to bed bug bites.
What is a Swallow Bug
These insects are ectoparasites, meaning they live on the outside of their host. They feed on the blood of birds, primarily swallows, martins, and swifts. These bugs are nocturnal feeders, emerging at night to seek out their blood meals. Their bites can cause discomfort and irritation to both birds and humans.
Swallow bugs are small, typically measuring about 3-4mm in length. They are brown or reddish-brown in color and have a flattened, oval-shaped body. These physical characteristics make them difficult to spot, especially in the crevices and cracks of nests or buildings. They are often mistaken for bed bugs due to their similar appearance.
The life cycle of a swallow bug involves several stages: egg, nymph, and adult. The females lay eggs in the nests of birds, and the nymphs hatch and develop through several molts before reaching adulthood. The entire life cycle can take several weeks to complete, depending on environmental conditions such as temperature and humidity.
Infestations often occur in areas where birds build their nests, such as eaves, attics, and wall voids. The bugs can travel significant distances from the nest in search of a blood meal. This mobility allows them to enter homes and other structures, even if the nest itself is not directly attached to the building.
Unlike bed bugs, which tend to stay close to their human hosts, swallow bugs are more likely to be found near the original bird nest. However, they can still be transported indoors on clothing or other items. This makes it important to thoroughly inspect any items brought inside from areas where birds are nesting.
The bites of these insects can cause itchy red welts on humans. The reactions can vary depending on individual sensitivity. Some people may experience mild irritation, while others may have more severe allergic reactions. Scratching the bites can lead to secondary infections.
Controlling an infestation requires a multi-pronged approach. Removing the bird nest is crucial, as it eliminates the primary source of the bugs. Treating the affected area with insecticides may be necessary to eliminate any remaining bugs. Professional pest control services are often recommended for effective treatment.
Prevention is key to avoiding infestations. Sealing cracks and crevices in buildings can help prevent birds from nesting and bugs from entering. Regularly inspecting potential nesting sites can also help identify and address infestations early on. Maintaining a clean and clutter-free environment can also discourage pest activity.
