Which ectoparasites are typically involved in invading buildings from bird nesting and roosting sites?

• A. Northern fowl mite and chicken mite
• B. Mosquitoes
• C. Ticks
• D. Bedbugs only

Answer: (A)

When looking at which ectoparasites are most likely to invade a building from bird nesting and roosting sites, the key idea is that some parasites live on birds and will move from nests or roosts into nearby structures. Bird-specific mites, such as the northern fowl mite and the chicken mite, are classic examples. They inhabit areas where birds roost or nest and can disperse into adjacent buildings, especially attics, soffits, or ventilation spaces, where they may bite humans when birds aren’t present or when numbers are high. This makes them the best fit for invading structures from bird nesting sites because their life cycle and behavior are tied to those bird hosts. Mosquitoes aren't tied to bird nesting sites in the same way; they breed in standing water and enter homes mainly for blood meals, not specifically to move from bird nests into buildings. Ticks typically enter homes by clinging to wildlife or pets and creeping in from vegetation, rather than migrating from bird roosts. Bedbugs are associated with human habitats and belongings; they aren’t typically moved into buildings from bird nests, even though they can be transported by people.
