Lovebugs on windows

Quick answer: Lovebug season (typically May and September on the Treasure Coast) leaves bugs and acidic residue on windows, sliders and lanai glass. The residue can etch glass and damage frames if left for weeks. Rinse with water soon after, don't scrub dry, and schedule a professional exterior clean at the end of the season.

Why lovebug residue matters

Lovebug bodies are slightly acidic, and when they dry on glass in the sun the residue bonds and can begin to etch the surface. It's the same reason they damage car paint. On lanai glass and sliders, where they collect in numbers, it turns into a speckled film that's hard to remove once it's baked on.

What to do during the season

Rinse glass with a hose every few days while they're active. Water alone lifts most of the residue before it bonds. Don't wipe dry; the bodies smear. If you need to scrub, use a wet strip washer and plenty of water.

After the season

A professional exterior clean at the end of May and again at the end of September resets the glass. We scrub the residue off with a proper washer, squeegee and detail the edges and frames.

Lanai enclosures collect them

Lovebugs drift into lanai enclosures and can't drift out, so the glass inside a pool cage collects far more residue than the front of the house. Rinsing the lanai sliders every few days during a flight, and letting them air dry, keeps the residue from bonding until the season's over and the glass can be properly cleaned.
