Not really, and anyone who's tried it at closing time already suspects as much. So, does bleach kill fruit flies? Technically, yes, on contact. But bleach rushes through your pipes far too quickly to reach the real problem: the sticky layer of organic buildup coating the inside of your drains, where fruit flies lay hundreds of eggs at a time. A generous pour might thin the crowd for a night or two, but the survivors will have the population back to full strength before the weekend.
Asking "will bleach kill fruit flies" is a bit like asking whether a bucket of water will put out a house fire. It's not wrong; it's just woefully insufficient. In a commercial setting like a bar, restaurant, or food service operation, drain biofilm builds up fast thanks to constant food waste, beer residue, and sugary liquids. Bleach won't strip it. Worse, it can corrode older pipes and create toxic fumes if it comes into contact with other cleaning chemicals already in the line.
And does bleach kill fruit fly eggs? Almost never. The eggs sit buried in that gummy biofilm, well protected from a quick splash of diluted sodium hypochlorite. The fix that actually works starts with breaking down that drain buildup using enzymatic cleaners designed for commercial drains. Pair that with sealed waste bins and regular professional service, and the breeding cycle stops. Pouring bleach, on the other hand, is the pest control equivalent of shouting at the television; it feels decisive, but nothing changes.
