It hasn’t even been 24 hours and those pesky critters (the flies, not the kids) are all gone!
Clear plastic bag or plastic wrap
A few pieces of cut-up fruit or citrus
Put the fruit in the cup, cover with plastic wrap, secure with the rubberband. Use the knife to make small slits in the plastic, about five or six. Leave it alone overnight or for several hours. The fruit flies will make their way down the slits to the fruit, but they cannot get back out. Once you have most of them, insert the whole thing in a plastic bag, tie it up and throw it in the trash outside. If you have a LOT of fruit flies, repeat until they are all gone.
Peace, love, and glitter!
