Well look, you might think I'm unashamedly biased here - well of course I am! But let's look at the evidence and feedback on these devices and see how well they work.

Deer can cause significant harm to trees, especially during autumn and winter when food is scarce or during rutting season when bucks rub their antlers. The key is to look for specific patterns of damage that distinguish deer from other animals like rabbits which make clean cuts.

There are basically two types of deer repellents that are worth considering. The rest are either largely ineffective, or just ridiculous! Repellents containing animal proteins or slaughterhouse waste are proven to be the most effective - and that's backed by field research!
