Fruit flies with Composting

We have been composting for a couple of years now and our biggest challenge is the fruit flies. We have a container that we keep on the counter and it really needs to be taken out daily. The container we have outside is great but now we need to work on keeping the raccoons out.

My husband did some searching and came up with a solution to get rid of the fruit flies.

Ingredients:
Yogurt cup with cover
Vinegar
Dish Soap

You punch holes in the cover. Add Vinegar and a dash of dish soap to the container. Stir so bubbles form and place cover on the container. Then place where the fruit flies are present. Keep out for a couple days and change the ingredients if needed. The flies are attracted to the container but can't get back out.
