How do you get rid og gnats in flower bed?

To make a homemade gnat trap you will need the following items.

Large Lemonade or Cola bottle, this can be a two or three litre bottle.

Scissors and sharp knife, these will be needed to pierce bottle and cut the top off the bottle.

Vinegar, Apple cider works the best, but you can use regular white if that's all you have on hand.

Sugar, just plain granulated sugar.

Water, enough water to fill the bottle half full.

1. Rinse out the lemonade or cola bottle.

2. Using a sharp knife, carefully go down about two inches from the top of the bottle and pierce the plastic, then using the scissors cut around the bottle taking the top off. You Don't want to cut to much or the top will not stay on your gnat trap when you turn it upside down.

3. Fill the bottle with half a cup of vinegar and half a cup of sugar (1/2 cup), and enough water to fill the bottle half full. Stir the liquid mixture around to mix the sugar in. Don't fill the bottle to full, or the gnats will be able to escape. The liquid should not be touching the opening of the bottle.

4. Place the lemonade or cola bottle top that you cut off on the bottle upside down into the opening of the bottle - if you find the top keeps falling inside the bottle you can use a piece of sticky tape to keep it in place. 5. Place the bottle in the vicinity of where the gnats are swarming or tie string around the bottle and hang it up around the trunk or branches of a tree.
