Kill It, Smash It

The spotted lanternfly feeds on a wide variety of plants, especially the tree of heaven, maple trees, and grapes. They're pretty tricky to catch as they're known for moving easily onto wood surfaces and vehicles.

This is not the first time we've been warned about this invasive species, We were told to KILL IT IMMEDIATELY.

The message hasn't changed!

Plant life will never be the same if we keep allowing this species' population to grow. We didn't do enough last year and now the experts are warning that we'll start seeing far more than ever before.

Just get rid of it.

The beginning of the fall season is the best time to kill lanternflies because September marks the beginning of the egg-laying season.


How to Kill Spotted Lanternfly Eggs

If you spot an egg mass, just scrape it with a credit card or something else that has a hard edge. You'll need to press hard enough on the egg mass to make it pop to know you completed the task. You can also toss the eggs into a plastic bag and squirt hand sanitizer on them to kill them or put the bag in the freezer to kill them. Whatever method you use just make sure they don't survive.


The following was shared by NBC Chicago and it includes some advice on what to do if you encounter the spotted lanternfly:

  • Report sightings - If you see SLF or suspect it, report it to A fact sheet, including photos, is available through the University of Illinois Extension.
  • Remove and destroy pests – crush nymphs and adults, scrape egg masses into a container with hand sanitizer or rubbing alcohol to kill them. Remember to take photos first, and report this!
  • Check your vehicles, boat, camper, outdoor articles, etc. - Before leaving an area, do a quick inspection for any life stages. Destroy any eggs or insects found.
  • Keep your eyes open and spread the word (not the pest) – We need the public’s help to look for and report this pest, and to also strengthen the outreach about it. It will likely impact everyone in Illinois one way or another, so the more awareness we have the better.
