What Are Spongy Moths and Spotted Lanternflies?
Spongy Moths

Spongy Moths are destructive, invasive insects that defoliate trees causing severe damage to forests and landscapes. Their egg masses look like fuzzy, tan patches and can be found on outdoor furniture, firewood, and vehicles. To limit its spread, early and prompt inspection is a must.
Spotted Lanternflies

Spotted Lanternflies pose a threat to crops, vineyards, and fruit trees. They are known to have striking spotted wings, and they lay eggs on hard surfaces such as barbecue grills and vehicles. Their eggs appear as grayish, mud-like smears on flat surfaces.
How Do Spongy Moths and Spotted Lanternflies Spread?
These pests spread when egg masses, larvae, or adult insects travel on household items during moving or transport. Anything stored outside such as grills, patio furniture, camping gear, and even moving boxes can unknowingly carry and spread pests.
How to Inspect and Remove Egg Masses
- Check all items carefully, especially anything that’s been stored outdoors. Look for eggs, masses, larvae, or insects.
- Remove egg masses by scraping them off into a sealed plastic bag filled with hand sanitizer or dish detergent and disposing in the trash.
- Clean your items by wiping down surfaces, shaking out fabrics, and checking inside crevices.
Complete Your Inspection Form
If your U-Box containers are being shipped to California, state regulations require you to complete the Invasive Pest Inspection Form to confirm that your items are pest-free. This simple step plays a big role in protecting California's environment while also ensuring a smooth move for you.
