Q: These are not little fruit type flies they are normal big black ones. Whenever I water my flowerbeds flies come out. I do not remember having this problem in past years. Is there something I can do or is this normal?

A: Brandi,
There are more than 100,000 types of flies. They may be showing up when you water for a variety of reasons-all considered normal. Certain flies like to breed in moist conditions. If you mulch around your plants, the flies may be attracted to the moisture from watering. Other flies may be preying on the insects that are inadvertently disturbed or washed off your plants while you water them. Watering may also trigger chemical scents on certain plants that some flies find attractive. Still others may simply be showing up for a drink. Whatever the reason they suddenly appear when you water; the flies usually won't be interested in your plants. They prefer "dead" food like manure, rotting plants and decaying organic matter found in nutrient-rich soil. Yearly populations can fluctuate with changing environmental conditions, and most flies complete their life cycle within a few weeks. As the season progresses, their populations will gradually diminish. Wear a hat and a good bug repellant to keep them at bay while you're watering the garden.
