It’s not uncommon to find Gnats and Drain Flies in or around bathroom sinks. These pesky bugs are attracted to moisture and damp areas, which can be easily found in sinks that haven’t been flushed for a while. The accumulation of hair and debris in the drain can create a stagnant environment, which is an ideal breeding ground for these bugs. To get rid of them, you can pour some white vinegar down the drain and rinse it thoroughly. Alternatively, you can also buy specific products from your local home and garden store and use them as per the instructions on the label. As part of our Professional Home Watch service, we always run water in each drain during our house checks. This helps to replenish the traps while also checking for any water leaks.
