Snake advice

In addition to squirrels we have had a snake in the yard. A friend sent me this advice and I thought I would share:

"I've gotten since we moved here and have a creek to the left of the property and a lake behind us. CRUSHED MOTH BALLS, you don't have to crush them much just stomp them and spread around the exterior of your hard, they WILL NOT cross it, something about the smell?? Don't know but I USED to see 6-8 footers on a regular basis and I HATE SNAKES then our lawn guy told me this trick and we re-apply every 2 or 3 months. They make something called snake away but it's just crushed moth balls and it's a lot more than moth balls. We put it on the outside of the fence line so that Jake stays out of them for safety reasons."
