It is really quite simple. But the more love you gave them, of course the more fertile they are.
So we also bought this:
Live composting worms
Remove the food sources attracting the flies. Fruit flies have a life-cycle of 10 days giving them plenty of time to punish you for leaving moist, fermenting, organic material in which they may lay eggs.
Step 2 - Catch and Release Trap
- Drop a piece of apple into a large, clean jar such as a Mason jar.
- Place the jar near the greatest concentration of flies, i.e., if they're hanging around the fruit bowl, put the jar in the fruit bowl.
- Put a paper cone with a small hole in the bottom in the mouth of the jar. It should have the pointed end pointed downward. The fruit flies will enter the cone through the large end by the mouth of the bottle and find their way through the hole into the bottle. They will not be able to get out.
- Release them outside when you have several, if you like.
