Lady bugs are generally beneficial insects that feed on plant pests like aphids, but when large numbers gather on and inside a home — often seeking shelter — they can become a genuine nuisance, especially with their tendency to leave stains and a foul odor when disturbed.
They typically cluster on sun-warmed exterior walls before finding their way in through small gaps and cracks.
Signs You May Have Lady Bugs
- Clusters of lady bugs on sunny exterior walls
- Beetles appearing indoors near windows, attics, or wall voids
- A noticeable odor when beetles are crushed or disturbed
- Yellowish staining on walls, curtains, or windowsills

We seal and treat common entry points — around windows, doors, siding, and rooflines — to stop lady bugs from getting inside, and apply a perimeter treatment to reduce the population gathering on your exterior walls.
