When a woodpecker opens a large enough hole in the side of your residence to pass through, they discover a wonderful new home has been created.
Although this may not appear to be problematic for you as the homeowner, it really is the beginning of what may be a very expensive problem. When rain or snow enters the wall through the holes, water damage inside the wall of your home is inevitable. Mold will develop and eventually will grow through the drywall into the air stream of the residence.
Stucco siding has been known to completely delaminate and fall off of the home.
A second risk to the home is the presence of Bird Mites left in abandoned bird nests inside the wall of a residence. The mites live on the blood of the bird then lay their eggs in the bird nest. The mites will continue to breed inside the wall, and then migrate into the living quarters of the residence.
The life cycle of bird mites consists of four stages: egg, larva, nymph and adult. The maturity process is completed in 7 days. The female mites, which are about 95% of the species requires a blood meal to produce eggs and start the cycle again. Because mites age to maturity so quickly, an infestation of a few mites is capable of staggering growth over a short period of time.
