Spotted Lanternfly Treatments

Why You Need to Schedule Your Spotted Lanternfly Treatments Now!

If you haven’t seen Spotted Lanternfly Nymphs on your property yet, take a closer look! Our office has been swamped with phone calls about controlling these nasty pests. While we anticipated a population explosion this year, the reality is even worse than expected! Read on to learn why you need to schedule your Spotted Lanternfly treatments now.

Spotted Lanternfly Cause Big Problems for Homeowners

Not only do Spotted Lanternfly pose a risk to the health of trees and plants, they also cause some really gross problems for homeowners. As the bugs feed on trees, they drip sour-smelling, sticky excrement called “honeydew”. It coats everything underneath where the insects are feeding. The tacky honeydew is difficult to remove from hardscapes, decks, cars, and other valuable objects on your property!

What’s even worse is that the tantalizing honeydew, along with the black, sooty mold that grows from it, attracts stinging wasps! Wasps will swarm your property, and that’s especially a problem if you have children playing in the yard.

Treatments Need to be Carefully Timed

Spotted Lanternfly has only been in the US since 2014.  To determine the best way to control this new invasive pest, Giroud has been working with researchers at Penn State and the PA Department of Agriculture.

Giroud’s Spotted Lanternfly Control program targets the pest during the Adult stage which occurs between July and November.  Why wait until the adult stage?

The Adult stage is when Spotted Lanternfly is most vulnerable to treatment.  Adults tend to stay in one place and attack favorite host trees.  As a result, we are able to kill the Adults when we treat the target trees at carefully timed intervals.

Giroud’s first treatment is done between July and September. This is a basal trunk spray that kills the pest on contact.  It’s also absorbed up through the tree’s vascular system and kills the bugs as they feed on the tree.  The treatment lasts for up to 60 days.

By September through November, the Adults can be found everywhere on the host trees. 1-2 additional sprays are needed on the trunk, limbs and foliage. This spray kills the insect on contact and the residual kills any Spotted Lanternfly that walk over or feed on the tree for up to 30 days.

“We’re confident that these treatments will do the job,” says Rodney Stahl, Jr, Giroud Plant Healthcare Manager. “The problem is that our schedule is filling up! July is already booked and August is beginning to fill up. Soon, we’ll have more requests for treatments than we can handle. Homeowners, who want to have their trees treated, need to call now before it’s too late.”

    how deadly is this treatment to other beneficial wildlife/birds/ insect?

      Hi Gail, This insecticidal treatment is a basal trunk spray that kills Spotted Lanternfly when they pierce the trunk area to feed.   As recommended by Penn State, we only apply insecticides after bloom is finished to help protect beneficials such as pollinators.  Additionally, this is a targeted treatment that is only applied on trees at high risk for Spotted Lanternfly.  This minimizes unnecessary use of insecticides.
