I recently had a fruit fly problem due to ripe mangos. The flies are now gone but the funny thing is I kinda wish I had some back.
I had some potted flowers on my windowsill. They were purchased at a grocery store so I knew they would not last long. I noticed they had begun wilting even though they were well watered so I threw them out. Lifting the flower pot I noticed this little guy sitting in his web. I also noticed all the corpses of fruit flys under his web. Pretty cool! Now to get some flies back so he/she has something to eat!
