FISH LAKE, Utah — Officials with Utah’s Division of Wildlife Resources are counting on insects to decrease the amount of Eurasian milfoil at one of Utah’s most popular fishing holes.

The DWR describes Eurasian watermilfoil as an aquatic invasive species that spreads rapidly and interferes with recreational activities like fishing and boating.

Divers went to Fish Lake Thursday and attached bags of weevil larvae to strands of milfoil.

“As the weevils emerge, a feast of Eurasian milfoil is waiting for them to munch on!,” a press release from DWR said.

A statement on DWR’s website said eradicating water milfoil is almost impossible, but biologists hope the weevil technique will reduce the amount of milfoil over time.

Other techniques used to control milfoil infestations include herbicides and mechanical harvesting.
