Birds or Wasps Nesting in Your Pool Cage

A pool cage's extruded aluminum frame and roof bracing create small, weatherproof cavities that both birds and wasps use for nesting — the same structural channels that hold the spline and mesh in place also happen to make a sheltered gap. In most cases, though, nesting is a symptom of an existing screen failure rather than its cause: something already had to give a bird or a wasp a way in, whether that was a torn panel, a gap at a corner post, or a door that was not latching flush.

Casselberry's water density — over 30 lakes and ponds inside 7.51 square miles — means more bird activity near most yards in the city generally, which is one more reason a small tear left unrepaired does not stay small for long here.

What to check

• Find the gap first — a nest is evidence of an entry point, and closing the entry point matters more than removing the nest once
• Corner posts and the top rail where roof meets wall are common entry points on an older frame where the fit has loosened over time
• A door that does not close flush is a common and overlooked entry point — see pool screen door won't close

Wasp nests specifically should be treated as a pest-control job before a rescreening job — that is not this business's trade, and a rescreen over an active nest just seals the problem inside a fresh panel.
