Spotted Lanternfly FAQ

What should I look for?

This pest is about an inch long and half inch wide with wings folded.  Nymphs (immature insect) are 1/4 to 1/2 inch long and develop in four stages, all of which are wingless.  Egg masses have a gray covering which may be dry as it ages.  Older egg masses may lose their covering and appear as columns of 30 – 50 seed-like eggs, these eggs may be found on trees, rocks or other hard surfaces.

Which trees do they attack?

Tree of Heaven, Red Maple, Silver Maple,  Box Elder, Norway Maple, River Birch, Black Walnuts, Willows, and Sycamore are among their favorites. Several others may be affected also.

Can you treat my trees?

Yes, we can.  The treatment is applied only to the trunk and is absorbed up into the branches killing Spotted Lanternflies as they feed on the tree in 1-7 days and protects the tree for 3-4 months.

Why does it matter if they’re on my property?

In mass, Spotted Lanternflies can kill your trees.  As they drink your trees’ sap, they spray “honeydew” on anything below your tree, creating a black sooty mess and attracting stinging insects. Shrubs and plants under trees can be damaged when covered in the sooty mold as well.

When should I get treatment?

Treatment should occur in July or August as the adults are on the move looking for places to lay eggs through the end of the season.  One adult can produce 30-50 MORE Spotted Lanternflies which will hatch next year.

What if I only have a few?

Even if you only see a few, they are possibly up in your tree tops out of sight. Kill the ones you see. New Spotted Lanternflies can move in any time as they spread across the state and country.

How long does the treatment last?

Treatment lasts 3-4 months.  Treat in July or August to carry your tree through the season.  

How much will treating my tree cost?

Measure the circumference of your tree(s) at chest height and tell us.  We can give you a price.

You treated my tree and there are still Spotted Lanternflies on it—why?

Spotted Lanternflies are on the move July through the end of October or early November. You will have dead ones and live ones on the tree until they feed from your treated tree and die.

What about my neighbors and neighborhood?

We will come out and talk to any groups, educating and providing desired services.
