Birds or Wasps Nesting in the Pool Cage

Intact 18×14 mesh keeps out small birds and stops most wasps from getting directly through the screen. When either is inside the cage regularly, the entry point is almost always a torn panel corner, a door that no longer fully closes, or spline that has lifted out of its groove — the same failures that show up on this site’s other symptom pages.

Where they actually get in

• A torn or gapped panel corner, especially low panels near a door where they are also most likely to be brushed against.
• A door that will not fully close or latch — see door won’t close.
• Spline lifted out of its groove, leaving a narrow but real gap along a frame member — see splines popping out.
• Gaps where a roof panel meets a beam, more common on older frames with worn extrusions.

Why it is a rescreen signal, not just a pest problem

If wildlife is getting in, airflow and insect exclusion are already compromised at the same opening. It is the same diagnostic logic as the mesh-condition checklist on the mesh guide — a gap wide enough for a wren or a wasp is wide enough that midges and no-see-ums are already using it too.

Wasps specifically

Nests often build in the dead space where the cage meets the house wall or tucked under a roof beam, which is outside the screen itself. Removing an active nest is pest control work, not rescreening — this business does screen work only, no pest treatment — but a torn or gapped panel near a nest site should be treated as the entry point worth fixing at the same time.
