Snake Crawls up a Wall. 02.10.2008 - Many people ask me about the climbing capability of snakes. In particular, people want to know if snakes can get up into their attic. The answer is that yes, some species of snake are excellent climbers, and can climb walls.
The grease is the way i went to stop adults climbing over my garden wall to retrieve their kids footballs. They thought it was quicker that walking around and knocking on my door..... Was amusing watching one attempt to climb my wall so he could get in the neighbours garden.he problem with grease on a fence or wall is if you have a cat that likes to use it as a thoroughfare, and then make himself a nest on your bed. Trellis would be my preferred option, though I've also got some hawthorn that's growing on my boundary too. MLH. 406 posts.
