What are you doing about lantern flies?

Post by ER2023 » Tue Sep 10, 2019 12:02 pm

Starting to get nervous about lantern flies. They are destroying our landscaping and now they are destroying some of our trees. Surprisingly, they did not touch our vegetable garden ... yet. We talked to several people and are getting different answers, including what Dept of Agriculture is recommending. We tried some of the recommendations, including a spearmint spray, but it's not working enough. Our local park ranger is telling us there is nothing we can do at this time because nothing on the market is effective. Feel helpless just standing by and watching the destruction. Has anyone found something effective to deter them?

I haven’t had to deal with lanterflies but I have had good experience using a soil drench of imidacloprid (also marketed as Merit or Bayer Advanced Tree and Shrub) to combat other sap sucking type insects. Apply in spring when plants begin leafing out.

There is some discussion online from county extension agencies that this treatment is at least somewhat effective.

Use only where needed as it kills beneficial insects as well as pests.

Can you share what state or region you live in?
They aren't a threat that I am aware of (at least not yet!) in our area (Northeast). A quick google search seems to indicate that some insecticides are effective.
Have you called local tree-care companies to see what they suggest?

We had trouble with the invasive wooly-adelgid and our Canadian Hemlocks so now get them treated twice a year by a professional (its an environmentally friendly treatment that smothers the buggers but doesn't poison the environment). The cost of treatment is better than losing the trees.

These things are everywhere in the Malvern area. Entire trees are riddled with them sucking them dry. Their corpses all over the path I like to walk. The forest smells like it's ROTTING. And before this year I've never seen a single one. It feels like the end of the world.

Thanks Kenkat, will research this more. It would be great to find something that was effective, yet not harming the beneficial insects.

Thanks DaftInvestor. We are also in the Northeast (PA), so very glad to hear you haven't seen any yet. I will try to contact some local tree companies to see what they recommend.

I agree with you Tamalak. It is almost unreal to see the damage they are causing.

Thanks for sharing this info. It was interesting to read about the NY State quarantine. This is a big issue and one that may only get much worse.

I'm west of Philly in Exton/Lionville area and if you can do it early enough its been helpful to place those sticky bands on the tree trunks.

After they've hatched I've used some of the bug killers with some effectiveness. Most of the stores have list of what has been effective. I have trees in my home that I've been trying to protect but these things are persistent...you can't let up.

We here in Upstate NY don't have this problem yet. When they come I will try various sprays at hand. I.e. I have an exterminator coming every 2 months to spray with natural oils against mainly ticks, though they also have an effect on mosquitoes. They had no effect on hornets, but me spraying with Bayer Complete Insect Killer did them in, which I would use when the lantern flies arrive here.
Corrected due to following comment.

A nursery owner said that the equivalent spray to that Bayer spray is using Permythrin in Bonide Eight Insect Control
No, these products are not very equivalent. It is more likely that the nursery owner wants you to buy the product that he sells.

The Bayer spray active ingredient is Imidacloprid, which is a neonicitinoid that gets absorbed into plant tissues and thus kills insects that feed on the plant, possibly some time after the chemical was applied. It is also used topically to treat for pests in mammals (e.g. fleas and ticks with K9 Advantix). Unfortunately, neonicitinoids appear to be implicated in bee colony collapse.

Bonide Eight Insect Control uses sulfur and pyrethrins. This is not normally considered to be a systemic insecticide, in fact a large part of the safety of pyrethrins is due to their rapid breakdown in the environment.

Bonide Eight Vegetable Fruit and Flower Concentrate uses Permethrin.

Here is a report on a study evaluating insecticides against Spotted Lanternfly. I suggest that you find products based on the active ingredients that do well against these pests. In particular, bifenthrin has long been available in insecticides that homeowners can buy.

The lantern fly is in my neck of the woods here in PA (Lehigh County). September is the beginning of the egg laying season.

"From far away, they look like splotches of gray paint; up close, like plaster or mud on your backyard furniture, playground equipment, stones and tree trunks."

"Each blob is teeming with 30 to 50 developing eggs of the invasive spotted lanternfly, and just as you might be tempted to hose off mud spots, the Pennsylvania Department of Agriculture wants everyone to scrape them if you see them."

That’s not mud on your yard furniture, but spotted lanternfly egg masses. Pennsylvania wants you to have no mercy.

I had some friends in PA that mentioned these. I assume they will eventually spread to all states in the general vicinity and probably the rest of PA ala kudzu. I know almost nothing, but I assume one could potentially eliminate them from one's yard by removing all sources of food. I looked at the list of preferred vegetation and where I live, we basically have nothing they could eat in most yards. On top of that, they can't fly well so it seems to me that a big buffer zone might be enough to keep them at bay if you have a big lot. They mentioned some killer fungus too but I think that stuff is still being studied. Other than that, I sometimes do controlled burns on some rural land that I have at the start of winter. Seems to cut down on bugs the next season so maybe it would kill lantern fly eggs too? Not sure though. Obviously would only work on a big plot in a rural area unless your neighbors have good sprinklers...
