Easy Fruit Fly Trap

Step 6 Remove hiding spots (op)

Now to really eradicate the little bugs you need to remove their hiding spots. This means removing their access to anything tasty except your trap. Put fruit in the fridge, seal it in plastic bags or cover it tightly. Throw out any fruit thats starting to spoil and take the garbage/compost out. You'll only have to do this for the first couple of days. The more disciplined you are at this the better and faster the trap will work.

In the summer when there's a lot of fruit coming and going I tend to forgo this and just leave a trap out all the time.
