How to Make Predator Urine Last Longer After Rain

Updated May 2, 2024

Predator urine is a completely natural, safe repellent for animals such as voles, rabbits, deer, moles, chipmunks, and other animals that love grazing on crops. I love the idea of using predator urine to repel these animals, but I admit to not using much of it because it washes away in the rain so easily. So how can we use predator urine, this wonderful organically-derived pest repellent, without going broke and having to re-spray it every time the scent washes away?

Hold tight, for I have the answer.

First, there’s a few things I dislike about spraying urine. 1) It stinks and is pretty disgusting to get on your hands, clothing, etc. 2) It washes away in the rain, breaks down in the sun, and doesn’t seem to last very long when sprayed.

I discovered a major vole infestation on my farm in early Spring 2022, after a long, cold winter with a heavy blanket of snow. The voles were having a field day eating my entire fall-planted cut flower crop while living underneath the landscape fabric I left behind on the pathways. This is a saga for another blog post, but I’ve ended my battle with the voles by adding plastic Tupperware containers of bobcat urine all over the farm.

Tupperware is the answer here, folks! I’m using “Tupperware” as a generic term for any sort of plastic food container.

Here’s how To get predator urine to last for a long time

Poke holes toward the top of a plastic storage container, on all four sides. I did this with floral snips and managed to not stab myself. I’d recommend using a pocket knife. I bought my plastic containers new at the dollar store, but any old food container will work — best if there is a slight lip on top so rain doesn’t go directly into the holes you poked.
Add a few tablespoons of urine to the container and put the lid on it.
Place one container every 10 feet around the perimeter of your space you hope to repel scavenging animals.
Add a heavy rock or brick on top of the container so it doesn’t blow over in the wind.
Keep coming back day after day, week after week, and stare in awe at the urine that is still in your container, repelling pests.
