1. Baking soda and vinegar

Baking soda and vinegar make an effective solution to roach infestations in the drains. Just mix equal amounts of baking soda and white vinegar in a cup, and stir the mix well until it is dissolved.

Pour the liquid down your drain, allowing it to sit no longer than 5 minutes before pouring in more hot water as a final blow to eliminate all of the roaches that you weren’t able to catch.

2. Pour Bleach

Bleach is an excellent disinfectant and will work equally well on bugs and pests like roaches.

Pouring a little bit of Bleach down your drain every once in a while can help stave off any unwanted guests for the foreseeable future so long as you leave it there for a good 20 minutes or so before flushing it out with plain water.

The bacteria in Bleach kill these vermin by creating a deposit on their exoskeletons which prevents them from breathing properly. Thus, they suffocate to death overtime.

Bleach is highly corrosive, and it damages drain pipes. Many people believe that pouring Bleach into the drains will unclog them and help get rid of the scum.

But in reality, all you’re doing is killing any bugs or germs down there because bleach is a disinfectant and cleaner.

Throwing down Bleach isn’t good for your drainpipe because eventually, the Bleach will corrode your pipes and cause more problems than you have now!

Save yourself time and money by calling a plumber to handle anything serious that may occur in your home’s sewer systems.
