Talking Trees Live: Spotted Lanternfly with Davey Arborist Jason Gaskill

The Wicked Spotted Lanternfly of the East

Aborist Jason Gaskill gives us the rundown on Spotted Lanternfly from Ridley State Park and what you need to know! You even get a chance to see this invasive insect (pest) on a tree. (00:05:46)

Where Did Spotted Lanternfly Come From? 

Native to China, India, and Vietnam, Spotted Lanternfly was first discovered in 2014 in Berks County, PA. (00:04:50)

The bug has also been found in Delaware, New Jersey, New York, and Virginia. (00:05:26)

What Trees are Affected by Spotted Lanternfly?

“What tree doesn’t it like” Jason explains. (00:08:08)

This insect is a threat to crops such as grapes, hops, and lumber. It prefers the tree-of-heaven but will attack other deciduous trees such as apple, oak, walnuts, maple, and willow.

Early detection is vital for the protection of several agricultural industries and your trees.

Contact your local Davey certified arborist if you are unsure if you have SLF or want a free tree inspection.

 

What do Spotted Lanternfly Eggs Look Like?

  • In early spring, look for all-black insects with white spots
  • Later in spring and closer to summer, look for bright red insects with white spots and black stripes
  • In summer and into the fall season, look for fully-grown flying insects with a set of brown wings with black dots, a set of bright red wings with black dots, and a yellow and black-striped body

How Do Spotted Lanternflies Damage Trees?

Here are common signs and symptoms of SLF tree damage to look out for:

  • Weeping wounds that leave a greyish or black trail along the trunk
  • Clear, sticky liquid called honeydew (00:06:17)
  • Leaf wilting and leaf curling
  • Black spotting on the leaf

Also keep an eye out for egg masses on trees and flat surfaces nearby:

  • Newly laid egg masses have a grey mud-like covering.
  • Old egg masses appear as rows of 30-50 brownish seed-like deposits in 4-7 columns on the tree trunk.

Arborist Jason also recommends checking under your cars and other smooth surfaces to help the spread of SLF. (00:18:47)

How Do You Get Rid of Spotted Lanternfly?

Proactive treatments can reduce the likelihood of spotted lanternfly killing infested trees. (00:12:18)

  • Use a systemic trunk treatment.
  • If the problem is more severe and ongoing treatment is required, you can also use a foliar insecticide.

Depending on the kind of systemic insecticide treatment, it can be applied during the growing season so in early spring and into fall. (00:16:21)

Homeowners can also be mindful of the types of trees in their yard and avoid planting tree species SLF commonly attacks.

What Do You Do If You See a Spotted Lanternfly?

Report all sightings to your state's Department of Agriculture.

You can visit your department’s website or give them a call to find out what information they’ll need to document the sighting.
