I purchased the DF 5000 to clear my drains and get rid of phorid flies. After using for a 5-7 days as directed, when can I expect to see the flies completely gone? In other words, how long do these annoying pests live?
The Phorid is a reproduction champion with females capable of laying forty eggs in twelve hours. Their entire live cycle is only about 25 days, so you can see how a population goes from zero to zillions in a very short time. How long it takes for the DF 5000 to get rid of the drain flies depends on how much organic matter has built up in the drain and if the DF 5000 is even getting in the right spot. Sometimes flies can be breeding much farther down the drain than just in the trap under the sink. Most of the time though the trap under the sink or tub is the issue and you just need to continue applying the gel. It can take a few days or up to two weeks sometimes depending on how much matter has built up. When this process is over you should treat the drains once every 30 days and you will prevent this from happening in the future.
