Trained Dogs in Cleveland Detect Over 4,000 Spotted Lanternfly Egg Masses
- Four specially trained dogs have searched Cleveland area parks since late 2024 to locate spotted lanternfly egg masses before they hatch.
- A Virginia Tech-led research initiative trained dogs to help control the spread of the invasive, sap-feeding spotted lanternfly, an insect native to eastern Asia that has become established in the U.S. Over the past ten years.
- The dogs search for concealed egg masses on trees, shrubs, park benches, rocks, and bridge pillars, finding over 4,000 masses that could produce tens of thousands of insects.
- In April 2025, specially trained dogs detected approximately 1,100 spotted lanternfly egg masses within a few hours at Cleveland Metroparks Zoo, contributing to the removal of up to 200,000 of these sap-sucking insects, according to senior conservation manager Connie Hausman.
- This canine-assisted effort suggests a practical method to slow the expansion of spotted lanternflies, which have spread widely across the East Coast and Midwest with limited resistance.

Four-legged investigators sniff out spotted lanternfly eggs to slow the spread of invasive pest
Researchers are deploying a new weapon to slow the spread of invasive spotted lanternflies. The pests first detected in the U.S. a decade ago have steadily spread across the East
Canine Detective Sniffs Out Spotted Lanternfly Eggs
The spotted lanternfly, an invasive species that damages leaves and first identified in the US a decade ago, is gradually moving across the East Coast and into the Midwest. Be cautious of its spread. However, researchers are now employing new methods to combat its expansion—specially trained dogs skilled at detecting insect eggs before they hatch.
