Why DIY Methods Always Fail
Save yourself time, money, and frustration. Here's why store-bought solutions don't work:
Boiling water flush
Problem: Boiling water does not reach deep into the drain where larvae and eggs are hidden
Result: Only kills surface flies, infestation quickly returns

Baking soda and vinegar flush
Problem: Baking soda and vinegar do not kill drain fly larvae or remove organic buildup
Result: Infestation quickly returns
Apple cider vinegar trap
Problem: Drain flies breed in the organic matter inside drains, not just around them, so the trap doesn’t target the source.
Result: Only a few adult flies are caught, and the infestation quickly returns.
Bleach solution flush
Problem: Bleach does not reach or eliminate eggs and larvae deep in the drain
Result: Infestation quickly returns
Stop Wasting Time and Money
The average homeowner spends $200+ on failed DIY attempts before calling professionals. Meanwhile, the infestation grows worse.
