These small larvae create silk bags covered with bits of sand, lint, or insect parts, attaching themselves to stucco, brick, or painted surfaces. While they rarely cause structural damage, their presence can impact the visual appeal of your home's exterior. To effectively get rid of plaster bagworms, start with a thorough physical removal—use a vacuum, stiff brush, or even gloved hands to dislodge and dispose of the cases. Next, power wash or hose down exterior surfaces to remove residual silk and eggs.To minimize recurrence, reduce potential food sources by sweeping away cobwebs, discarded insect parts, and plant debris near your walls. Seal cracks or gaps where adult moths might enter to lay eggs. If bagworms persist despite cleaning, you may consider using an outdoor-safe insecticide targeted for moth larvae, but always follow manufacturer instructions. Because moisture and organic debris attract bagworms, consistent home maintenance remains the most effective long-term strategy for prevention.As a designer, I always recommend that maintaining clean and aesthetically pleasing exterior walls is key to your home's curb appeal. Efficient removal and prevention strategies will not only enhance the life and look of your wall finishes but will also provide a clean slate for any future interior design improvements you plan to make. A well-kept exterior often inspires better interior upgrades!Tips 1:Inspect your exterior walls regularly, especially in humid or shaded areas where bagworms often thrive.
