Hi Karen, fruit flies are not always the result of rotting or fermenting fruit. They can also be drawn to food odors, garbage, and sometimes just plain stagnant water.
The thing to remember is that fruit flies can go from egg to adult in as little as a 8-10 days. The adults don't live that long, but the breeding can be continuous.
Biodrain is good for drains and phorid flies, but it only works if there is a greasy or gunky buildup in the drain. If the fruit flies are breeding or propagating somewhere else, then treating the sink is useless.
Generally, when you have a fruit fly, phorid fly or fungus gnat problem, there is a reason. That reason is usually a breeding source. It needs to be found and eliminated. Fruit, vegetables, garbage, standing water (under the house, inside a wall void, outside the house) can also provide a breeding ground.
If you have leaking plumbing (under a sink, bathtub, shower, or under a dishwasher, under a refrigerator), can also be a problem.
Over watering house plants can also create a source.
In any event, you have to eliminate the breeding source, then go after the adults. Gentrol or Gencor can be used as a "growth regulator" to help eliminate the life cycle. But it has be applied to the areas where the flies are breeding.
CB80 is a pyrethrum aerosol that is used like a handheld fogger. It can fog a complete room in a few seconds. This will kill adult flies.
Fruit fly traps are also effective at capturing adults.
The garbage disposal could be an issue, but if you pour bleach down it regularly it will eliminate it as a source.
Fog, trap, and eliminate all breeding sources.
Hope this helps.
