Beyond the initial treatment, there are a few recurring costs to factor into your spotted lanternfly budget, from free DIY inspections to professional preventative visits.

DIY Prevention

Conducting regular inspections of your trees will cost you nothing but time, so it’s worth adding this preventative step to your routine. Look closely at your trees and scrape off any eggs and kill any bugs you find. Be sure to contact your local insect control specialist if you suspect the spotted lanternflies are taking over again.

Ongoing Treatments

Ongoing preventative visits from a pest control service cost around $40 to $70 per month or $100 to $300 quarterly, and scheduling them regularly is a smart way to keep spotted lanternflies from returning even when you haven't seen any activity recently.

Why You Should Hire a Lanternfly Treatment Pro

Hiring a local lanternfly treatment pro costs more upfront, but you benefit from safer application methods, correct product usage, and treatments that effectively target every stage of the insect’s life cycle. Pros bring the proper licenses, equipment, and knowledge needed to control an invasive pest without harming nearby plants, pets, or beneficial insects.

Here’s why it’s ideal to hire a lanternfly treatment pro

Treating spotted lanternflies involves identifying host plants, timing treatments correctly, and using regulated products safely. Here are some of the top reasons to work with a pro:

  • Professionals know how to inspect trees and shrubs for egg masses, nymph clusters, and adult feeding damage, ensuring the full infestation is addressed.

  • They are licensed to apply pesticides legally and safely, including systemic treatments and targeted sprays approved for lanternfly control.

  • A pro reduces the risk of harming desirable plants, pollinators, or surrounding landscapes by selecting the right products and application methods.

  • Many providers can bundle services such as egg mass scraping, tree band installation or replacement, and follow-up treatments for long-term suppression.

If you want to DIY parts of the treatment process

If you want to handle some tasks yourself, these DIY steps can help reduce time and labor costs:

  • Scrape and destroy lanternfly egg masses on trees, outdoor furniture, and hard surfaces during the fall and winter months.

  • Remove clutter and debris around your yard to make inspections and treatments easier for your technician.

  • Identify and note the trees or plants where you see the most lanternfly activity so your pro can target the right areas immediately.

Spotted Lanternfly Additional Costs: What to Budget For

If you're dealing with other unwanted insects or arachnid invaders on your property, many bug control specialists offer discounted rates for bundling multiple treatments. Costs for common add-on services vary widely depending on the pest, so reviewing the breakdown below can help you plan your full budget.

Tips to Reduce the Cost of Spotted Lanternfly Treatment

The cost of spotted lanternfly treatment can get steep, especially if you need to treat multiple trees. Here are a few ways to save money and help prevent the spread of spotted lanternflies:

  • Get at least three different quotes from reputable insect control specialists before hiring pest control services.

  • Always check your vehicle and belongings for spotted lanternflies to avoid spreading the invasive insects or bringing them home, especially if you’re near a heavily wooded area.

  • If spotted lanternflies are invading your community, reach out to your local municipality to help control the insects in your area. States like New Jersey and Pennsylvania have government-funded programs to help towns and communities survey and treat spotted lanternfly infestations.

Next Steps: Finalize Your Project With a Extermination Pro
  • Let your pro know where you’ve seen the most lanternfly activity so they can plan the best treatment spots and tools.

  • Ask what types of treatments they use (chemical, natural, or both) and whether any may affect plants, pets, or outdoor furniture.

  • Discuss whether you need to prep the area first—such as clearing debris, trimming vegetation, or moving items away from walls.

  • Check whether follow-up visits are recommended and what those may cost, so you’re not surprised later.

  • If you have delicate landscaping or outdoor structures, mention them upfront so the technician can adjust their approach.

Frequently Asked Questions

According to scientists at Penn State University, spotted lanternflies do not typically kill the trees and plants they feed on, but they can cause branches and segments to die off. However, they have been found to kill cultivated grapes, which can have devastating consequences for vineyard owners and regions that heavily rely on vineyards to create jobs and generate revenue. They have also killed the Ailanthu altissima, known as the tree of heaven, though this is classified as a noxious and invasive weed tree.

Yes, if you see a spotted lanternfly in a municipality where it is not already known to exist, you should report it to your local agricultural department or extension office. Kill the insect immediately by crushing them or stepping on them. If you see any egg masses, scrape them into a sealable plastic baggie or container and cover them with rubbing alcohol or hand sanitizer to kill them.

Not likely. While the occasional spotted lanternfly insect may find its way in, it’s highly unlikely that spotted lanternflies will lay eggs and eventually infest your home because they prefer to live outdoors. If you’re concerned about the bugs getting inside, be sure to examine all humans, objects, and pets before bringing them indoors.

While the spotted lanternfly’s favorite place to stay is the trees and plants they gorge on, they can occasionally congregate in large numbers on buildings and other structures. This may be for height, warmth, or other unknown reasons. However, rest assured that the insects do not do any structural damage to the buildings, and will likely move on within a few weeks or perish with the colder weather.

No, the spotted lanternfly does not sting, bite, or otherwise do anything painful or damaging to humans or animals. Do not hesitate to approach and kill the insects and any eggs you find on sight—you’ll be playing an important role in slowing the spread of these invasive and destructive pests. If you’re not sure if the insect is a spotted lanternfly, snap a picture and contact your local extension office for help identifying it.

To help protect local ecosystems, the U.S. Fish & Wildlife Service urges citizens to educate themselves on how to identify and kill spotted lanternflies, including adults, immatures, and their eggs. It’s also crucial to check vehicles and belongings for the insects before traveling to avoid spreading them to new areas. Lastly, become familiar with your state’s reporting tools, take pictures if possible, and include the location where the picture was taken.
