I don't know if what I'm going to describe happens in your neck of the woods, but every late summer in lower Delaware, we're inundated with fruit flies! One year, it was so bad, we had to stay in a hotel while the house was "bombed". That was the year I made the critical mistake of bringing a bushel of pears from one of our fruit trees into the house! This year, for the first time, the fruit flies are virtually absent. We have seen a few, but nothing like in years past. Any thoughts on why the fruit flies are scarce this season? For our parts, we've done nothing differently. We still wash our bananas before setting them out, and we keep any potential fruit fly treats washed and under wraps.
