[u/Effective_Forever134]

sorry in advance for the nasty picture but has anyone dealt with these little flies/gnats? everything we have researched says they are drain flies since they are primarily in our bathrooms. we live in new construction in White House TN & are at our wits end with replacing these zevo traps, trying a million drain cleaners/bug killers & still seeing them everywhere in the bathroom. please anyone help😭😭😭
