Be on the lookout for the Hammerhead Worm!
The worm in the picture was captured in Warren County. Dr. Jermaine Perier, MSU Extension Entomologist for Vegetables, Fruits and Nuts gave us the following information:
1. Never handle the worm without gloves: Their mucus can be an irritant and some species produce neurotoxins.
2. Dispose of the worm WHOLE. The worm is able to regenerate from its body parts, so cutting it up will only produce more.
3. Make sure to use an airtight containment method to prevent escape.
4. Ways to kill the worm, which might take 1-2 hours:
a. add salt to the container
b. soapy water in the container
c. leave container in direct sunlight
d. soak in ethanol, alcohol, or hand sanitizer
5. Report sightings! The worm is invasive to the U.S. and some species have been here for some time now (since 1981). Still, we want to be able to track populations to monitor their spread.
. Sightings can be reported at EDDMaps shovel-headed garden worm (Bipalium kewense Moseley, 1878) - EDDMapS State Distribution - EDDMapS and clicking the report sighting tabs and following the instructions.
