Imported Cabbage Worms Are Chewing up My Garden!

One of the worst things to observe in your garden are caterpillars heavily defoliating your plants. But unfortunately, that’s exactly what the imported cabbageworms (cabbage white) caterpillars do.

Squash Vine Borers Strike Again: This Time They’re in the Produce!

The larvae of the squash vine borer can wreak havoc on squash plants by boring into the stems and slowly killing the plants. Unfortunately, they’ll do even more than that. They will also invade the developing produce.

Watch Your Squash! Squash Vine Borer Moths Are Active.

Monitor Lawns and Gardens for Bronzed Cutworm Activity

Bronzed cutworms can be an issue for lawns and gardens in South Dakota. In grass, bronzed cutworms will feed and leave small brown circular patches. Large populations of bronzed cutworm can result in severe lawn injury.

No, It’s Not a Murder Hornet.

By now, you’ve probably read headlines about the Asian giant hornets (aka “murder hornets”) that were spotted in Washington state and across the border in Canada. It is important to note that Asian giant hornets have only been confirmed in a small area of Washington and Canada. These wasps have not been observed in South Dakota or our neighboring states.

Wasp Activity Is Ramping Up

With their distinctive black and yellow stripes and tendency to hang out in groups, wasps receive attention no matter the time of year. As the weather warms up and spring progresses, you may notice more wasp activity in your yard or around your house.
