Bird mite infestation in a home can occur even without the presence of a pet bird. Bird mites will leave empty bird's nests in late spring and early summer to look for new hosts. The new hosts often turn out to be the occupants of a nearby housing unit.
Bird mites are extremely small and cannot be easily seen without magnification. Once a house is infested, it is difficult to eradicate the mites.
A good way to confirm if you have bird mites is to place a pan of hot, steaming water into the middle of a darkened room. Place one source of light over the pan and leave the room undisturbed for a couple of hours. When you return, you should be able to see mites in the water with the aid of a magnifier.
If you don't own any birds, bird proof your home by screening chimneys, covering broken eaves, and trimming tree branches and limbs that overhang the home. Bird owners should use plastic or metal aviaries to eliminate crevices that can be used as hiding places.
The best treatment for a home is to have it tented and fumigated. Pet birds should be taken to a veterinarian for treatment and any outdoor birds that have taken up residence in your home should be removed.
Sometimes having a home tented for fumigation is not an option. An alternative is to fog the home. Foggers can either be thermal or ultra low volume (UVL). The effectiveness of the fogger will depend on the chemicals used, and the application must be repeated after seven days.
