Insecticide For Spotted Lanternfly Nymphs

The spotted lantern fly (Lycorma delicatula) is a non-native invasive planthopper that feeds on over 70 plant species, including many important agricultural crops and ornamental plants. It can cause major damage or death to trees. The insect has recently been discovered in the United States (U.S.), where it threatens crops in at least 21 states, including crops in Michigan and Pennsylvania, which produce apples and grapes, respectively. Outbreaks of the insect could lead to substantial harm to U.S. agricultural industries.

If you find Spotted Lanternflies in a municipality where they are known to exist, you should try to kill them.
The most effective way to eliminate these insects is to disrupt their favorite food and hang‐out. In late summer and fall, Spotted Lanternflies prefer feeding on Ailanthus altissima, commonly known as the “Tree of Heaven.” They can be found feeding on other plants and trees, but Ailanthus altissima is their favorite host.

If you have Ailanthus on your property: please consider reducing the number of Ailanthus trees, then treat remaining “trap trees” with insecticides. This is a longer‐lasting solution than simply spraying insects you see.

If you want to kill Spotted Lanternflies without controlling Ailanthus: When there are only a few insects, you can kill spotted lanternflies by swatting or crushing them. For large populations, two kinds of insecticides are widely available that will kill Spotted Lanternfly adults. Contact insecticides kill spotted lanternflies when the chemical contacts the insect directly. Systemic insecticides are absorbed by the tree and kill insects feeding on it. ALL insecticides must be used as directed on the label. Take the time to read the label carefully and follow the directions. This increases your safety, the safety of the environment, and the effectiveness of the insecticide.

Pennsylvania law requires that pesticide labels list the site where a pesticide (such as an insecticide) may be used. In Pennsylvania, insecticide labels do not have to specifically list the targeted insect. There are insecticides labeled for use on ornamental trees and around buildings. These products are legal to use on the sites listed in order to control Spotted Lanternflies in Pennsylvania.

Penn State Extension is currently testing to determine which insecticides are most effective in controlling adult spotted lanternflies. Preliminary results show insecticides with the active ingredients dinotefuran, imidacloprid, carbaryl, and bifenthrin are effective at controlling the spotted lanternfly. Neem oil and insecticidal soap provided some control, but results varied, and insects sometimes took several days to die.

There are many available insecticide products containing the most effective ingredients studied (dinotefuran, imidacloprid, carbaryl, and bifenthrin). There are two types of insecticides that can be used in landscapes and non-edible gardens: Contact insecticides and Systemic insecticides. Contact insecticides (bifenthrin, carbaryl) should be applied when adult insects are present. Systemic insecticides (imidacloprid, dinotefuran) are most effective when applied in spring and summer, before adults build up. There are also insecticides you can use on vegetables, fruit, berries and grapes. When using insecticides on edible crops, it is especially important to follow directions for chemical application and timing from harvest as stated on the label.

Spotted Lantern Fly is a pest that can be extremely destructive to fruit and vegetable crops. In order to contain this pest, it is important to use an insecticide that will kill the Spotted Lantern Fly while still being safe for humans and other animals.

There are several different insecticides available that can be used to kill spotted lantern flies, but most of them are not safe for humans or animals. One of the most common insecticides is Pyrethrin, which is derived from chrysanthemum flowers. This chemical does not harm human skin or eyes when used in small doses, but it has been known to cause irritation in some cases.

Another option is malathion, which is considered to be safer than most other insecticides because it does not penetrate the skin as deeply and therefore has fewer side effects. However, malathion can cause eye irritation or damage if you get it on your face or hands; make sure you wash thoroughly after handling this product!
