The usual suspects
Screens either keep bugs out or they don't — so when insects show up inside a screened lanai, there's almost always a findable entry point. Roughly in the order we encounter them:
- Small tears and punctures — even a coin-sized hole is a highway for mosquitoes
- Worn or shrunken spline — the rubber cord holding mesh in its groove ages, letting panel edges lift
- Door gaps — a worn sweep, a sagging hinge, or a latch that doesn't pull the door tight
- Panels pulled loose at the frame — often high up where you won't notice from a chair
- Standard mesh vs. tiny insects — no-see-ums can pass through some standard weaves even when the screen is intact
What you can safely check yourself
- Walk the cage at eye level and scan each panel against the light — tears show up as bright lines
- Check every door: does it close tight on its own, and does the sweep touch the floor?
- Look along panel edges for lifted spline or mesh pulling out of the groove
- Do your checks from the ground — leave roofline panels to a technician
If it's no-see-ums specifically
If your screens look intact but tiny biting midges still get through, the mesh weave itself may be the issue. Tighter no-see-um mesh exists exactly for this — see our guide comparing it with standard mesh, and a technician can confirm whether it suits your enclosure.
Getting it fixed
Most bug-entry problems are on the smaller end of screen repairs — a panel here, a door sweep there. Request a free estimate, mention where you're seeing the bugs, and share photos if you have them. The fix is confirmed after a technician looks at the enclosure.
