This is easy peasy... Just buy a portable fence stake that can be found at most local feed stores. They easily "step in" to the soil and set your Bite Free Stable Fly Trap down on it making sure the bottom of the trap is about 1 foot (no more than 3 feet) above the ground or grass! Voila! It's the correct height to catch heaps of biting stable flies and can be easily relocated if you wish!

And remember to order your Fly Predators for this season if you already haven't!

Here's an image of the portable fence stake. I use the shorter of the 2 as that puts the Bite Free Stable Fly Trap near where the horses legs would be and right where those pesky biting flies attack.
