BATTLE CREEK, Mich. (AP) — Part of a path in a southern Michigan city park has been closed due to a wasp infestation.

The Battle Creek Enquirer reports Thursday that the critters have been identified as yellow jackets.

Nests were found near a clearing. Battle Creek officials say areas where the nests are found will be sprayed.

Officials initially reported the infestation was by bees.

No wasps have been found at a playground near the Linear Park path.

The Kalamazoo Gazette has reported that they were discovered after members of a family walking their dogs in Linear Park were stung.

Yellow jackets are aggressive and, unlike honeybees, don’t have to stop after one sting.
