If you are having problems with fruit flies in your house or cellar it's easy to get rid of them. All you need is a mason jar with a lid, a nail, and some apple cider vinegar. Take the lid and poke holes in it with the nail, add the apple cider vinegar to the jar (not a whole lot) put the lid on the jar and set it near where the problem area is. TaDa! No more fruit flies!
 

To stop fleas from getting on my dog's coat I sprinkle on a few drops of lavender.
