Are those the same as "horse apples" out here?
You'd think that they would take out the occasional squirrel...
I don't know but they may be. Some call them Osage oranges and other names around here. I have been to farmers markets that sell them by the pound as a spider repellent. I know it doesn't work though because I have put them in my basement and have had to throw them out with spider webs on them. LOL
