How to Stop Roaches From Coming Up the Drain

Take immediate action if you happen to spot a roach coming up your drain. While an occasional roach may not appear to be a major ordeal, it may be indicative of a whole colony of roaches living nearby. Roaches cause problems to asthma sufferers, and also carry disease-causing germs. Because roaches like dark, moist areas, drains are a preferred hiding place. Roaches may frequently be found in kitchen and bathroom sinks, and in bath tubs and shower drains.

Ensure all of your pipes are well tightened. Look for any leaks, and use the plumbing patching kit as needed. You will make the area less attractive to roaches by fixing leaks.

Scrub down the bathroom and kitchen -- including sinks and drains -- using hot water and dish soap. This will help kill roach eggs and eliminate faeces. Cleaning the area also removes aggregation pheromones roaches use to attract other roaches to the area. Wipe cleaned up surfaces using the absorbent towel.

Open your kitchen or bathroom window to ensure ventilation. Put on your protective mask and remove the drain covers. Pour some bleach down the drains in your kitchen sink, bathroom sink and shower. Roaches are not particularly fond of the smell of bleach.

Replace your ordinary drain covers with drain covers with smaller holes. Roaches will no longer be able to fit through them, and will be unable to enter and exit at will.

Place the sticky traps in areas roaches are likely to frequent. Place then behind drains, behind sinks and inside bath tubs. Place them in other areas of your home; roaches will seek a new access point if the sinks and drains are blocked.
