Raccoons!

What height should I build a fence to keep out Raccoons?

I put a pond in a few months ago and ever since I've lost tons of money in fish and plants, not to mention how hard the upkeep has been on my pond because of raccoons. Just last night I lost one 8" beautiful koi and one 6" butterfly! I've had it. I've tried all the home remedies.. cayenne pepper, ammonia and now I've decided to fence off the area where I think they are coming in from. Since I rent I want to spend as little as possible since I'm about $800 in with this pond as it is.

I had put up a 3 foot fence near some stairs because of my 2 year old but now would like to fence off a 20' section to try and keep them out. Any ideas on how high I should make it? I know the best would be maybe 5' or so but I would like to keep costs down. Does anyone know if they can climb over a 3 or 4' fence? I will be planting rose bushes along the back of it (I am moving them from another area of my yard) because I've read they hate thorny plants.

Any other ideas would be great. I cant use a scarecrow because of the size of my yard and location of my patio furniture.
Please help!




You could try planting prickly plant material around your pond. Burford Holly works well. So does asparagus fern. But if they want your fish, they WILL get it.
And you have to sink the fence as well because those critters will dig under it. Dig down under the fence and put chicken wire in so they can't dig through.
