Mostly birds and the occasional squirrel will use wall vents as ready-made nesting boxes. The existing plastic vent cover presents no obstacle whatsoever against animals seeking entry.
Once inside the vent pipe starlings will construct large nests, sometimes 1 meter in length, often blocking the air flow. With up to 6 fledglings defecating in this confined space, breeding insects and obnoxious odours are a most undesirable consequence. An easy solution to prevent these intrusions is to fasten galvanized screen on top of the plastic vent cover. The screen installation must, however, not interfere with the normal functioning of the vent flaps.
Warning: Dryer vents should not be screened, as this would cause the accumulation of lint against the screen and inside the pipe, thus presenting a fire hazard.
