Part 4/5:
The exact manner in which these invasive worms entered Missouri remains uncertain. Sokolowski speculates that they were likely unintentionally imported alongside soil used for horticultural or agricultural purposes. This could mean that the hammerhead worms were stowaways in the potted soil of landscaping plants or agricultural imports.
Seasonal Behavior and Handling Precautions
As temperatures drop, hammerhead worms burrow deeper into the ground, making them harder to detect. Residents are advised to approach any sightings with caution. Sokolowski emphasizes that these worms possess a toxin that they release to subdue their prey. Handling them carelessly can result in skin irritation and rashes.
