Frequently Asked Questions
Can I spray these insecticides directly on my vegetable garden?
Most potent insecticides for lanternflies are not labeled for use on edible crops. Using them on your tomatoes or peppers could leave harmful residues that you definitely do not want to consume. Check the product label for a specific list of approved plants before you spray anything near your food.
How often should I reapply the treatment?
Most residual insecticides require reapplication every four to six weeks depending on how much rain you get. If you notice a fresh wave of nymphs or adults, you might need to treat the area again sooner. Keep a log of your last application date to ensure you stay within the legal usage limits listed on the container.
Do these products kill the eggs as well?
Unfortunately, insecticides are not effective against the waxy egg masses that lanternflies lay in the fall. These masses are incredibly tough and usually require physical removal with a scraper or a stiff putty knife. Focus your chemical efforts on the active life stages when the insects are actually moving around.
Will my pets be safe if they walk on the treated lawn?
You should keep all pets and children off the treated area until the spray has completely dried. Once the liquid is absorbed into the bark or soil, it is generally much safer for foot traffic. Always read the re-entry interval on the back of the bottle to see exactly how long you need to wait.
What if I have a very tall tree that I cannot reach?
If the infestation is in the canopy of a massive tree, you may need to call a professional arborist. They have specialized equipment to reach the highest branches where lanternflies like to cluster. Attempting to spray a thirty foot tree with a standard garden sprayer is like trying to put out a forest fire with a squirt gun.
