Frequently Asked Questions
Can I use dish soap and water instead of commercial insecticides?
A mixture of dish soap and water can kill individual lanternflies on contact, but it lacks the residual power needed for long-term control. It acts like a temporary fix rather than a real defense strategy. You will need a chemical insecticide if you want to stop a large infestation from spreading.
When is the best time of year to spray?
You should aim to spray during the late spring and summer when the nymphs are active and growing. Once they reach the adult stage in late summer, they become much harder to manage. Focus your efforts before they begin laying eggs in the autumn.
Will these insecticides hurt my pets?
Most chemical insecticides are dangerous to pets until the product has completely dried on the treated surfaces. Keep your animals indoors or restricted from the area while you are spraying. Once the liquid has evaporated, the risk to your pets usually becomes much lower.
Do I need to spray the leaves or just the trunk?
Spotted lanternflies primarily feed on the phloem of the tree, which is found in the trunk and branches. While spraying the leaves can help, focusing your application on the bark of the trunk is often more efficient. This is where they spend the majority of their time congregating and feeding.
How often should I reapply the treatment?
Check your product label for the specific reapplication interval, which is typically every two to four weeks. If you notice a new influx of insects after a heavy rain, you might need to apply a fresh layer sooner. Consistency is your best friend when dealing with these persistent pests.
