My friend Dani told me about this fly trap, and so for the last couple of years, we have NO problems with fruit flies. I saw one last week. I recharged my trap, and this is what I found in it yesterday:
The recipe is extremely simple. Mix a couple tablespoons of apple cider vinegar and a couple of drops of dish washing detergent.
Set the trap near where you store your fruit, and then start counting bodies.
I just leave the trap out until it evaporates, then I rinse it out and start again.
We don’t see fruit flies any more, except in the trap. They hatch and are lured to their death almost simultaneously, it seems.
Best of all, this is a perfectly safe pesticide solution.
