A noxious weed has become a thorn in the side of county leaders who want to get rid of it.

It's called a Goathead. You may know it as the spiky seed that deflated your bike tire, or got into your pets paw.

According to the Idaho Weed Awareness Campaign invasive weeds including, Goatheads, have infested 8 million acres of Idaho's lands and pose a serious threat to Idaho's economy.The state and private land owners spend 30 million dollars a year to fight noxious weeds.

"They tend to die out in the frost but the seed itself lives in the soil for 20 years so they're a constant problem," said Cory McClymonds of Zamzows. If you are looking to get rid of Goatheads in your backyard, officials remind you to use herbicides safely.
