Uptick in slugs is plaguing Dillingham farmers and gardeners

Slugs are nothing new to gardening in Alaska. There are several species native to the region and some that are invasive. However, Dillingham gardeners report that there has been a major uptick in slugs in the last few years.

"The slugs have moved into the bay, so our greens have not done as well because of that," said Toni Hermann, referring to Bristol Bay. She runs Warehouse Mountain Farms with her husband Mark Hermann.

He added, "We think with the warm winters, the last four to five warm winters that we've had, have probably helped with them increasing."

Mark Hermann has heard from gardeners around the state who are dealing with an influx of slugs.

"Farmers in the Valley and in Fairbanks — I mean it's pretty much across the state — are dealing with the same thing. It's not just us," he said.

The slimy critters have added a lot of extra work to their farming effort. The Hermanns use bait to attract and trap slugs in their greenhouse. For the crops that grow outside, like cabbage, they have to plant more and count on losing
part of their crop to slugs.

"It probably adds 25 percent to the labor, cleaning up, trimming and packaging. Where before you could pretty much pick right out of the field into the bag, now you can't do that any longer," he said.

Patricia Treydte, who has run Unicorn Gardens for 35 years, has noticed the increase as well.

"Trying to get greens without holes in them has been next to impossible. I've wasted a tremendous amount of my time going out every morning, early in the morning, sometimes in the middle of the night with a headlamp, murdering
slugs. There seems to be an endless number of them. They just keep coming," Treydte said.

Neither Treydte nor the Hermanns have identified the type of slugs plaguing their gardens. But Treydte said that she found the soil was full of slug eggs when she harvested her potatoes, so it seems these slugs may be sticking around
for another year.
