How to Stop Cockroaches from Coming up the Drain?

Identify Where They Come From

Cockroaches are very hardy animals. To prevent roaches up your drain, you first need to know where they come from. Follow the connection of your drain and try to find out their source. It could be the main septic tank or a leak on the drain pipes.

If it is a leak, use cement or duct tape to cover the entry point. If you think the main septic tank is the cause, you need to alert professionals because dealing with septic tanks is dangerous.

Eliminating Water Sources and Entry Points

Water is the essential survival commodity for any living creature. When you eliminate all the water sources in your drain, the cockroaches will find the living conditions a hurdle. Standing water tends to attract these creatures. Therefore you need to cover all the holes or points where stagnant water rests.

Use duct tape to cover cracks around the pipes and silicon or even cement to cover larger cracks. By removing any source of hydration, they will seek to find another place with better conditions.

Maintaining Cleanliness

Giving roaches unbearable conditions is the first thing you need to do. But that would all be in vain if you don’t maintain cleanliness. All appliances, counters, and even utensils near drains should always be clean.

Empty your dustbin as frequently as possible so that the foul smell does not attract the roaches again. After every meal, you should clean the utensils and leave the sink as clean and dry as possible.

Trap and Kill the Roaches

This method is one of the easiest ways you can use to prevent roaches up your drain. Apply gel bait on specific parts of the drain. When a single cockroach comes into contact with the gel bait, it can course detrimental effects on the roach family.

When one is contaminated and goes back to the others, they all will die as long as they contact the affected one. The effect goes on and on, and the contamination spreads to all the roaches. However, this method only creates room for other cockroaches to infest.

What do You Pour down the drain to get Rid of Cockroaches?

You must clean your drains regularly with chemicals to kill and provide uninhabitable conditions for the roaches. Use foam cleaner to remove grease and other food traces in your gutters.

Bleach also works perfectly and can even kill the cockroaches. However, you need to be careful when dealing with bleach, especially if you have a septic system. The reaction between bleach and ammonia is not something you want happening in your drains.

Cleaning chemicals such as alcohol-based solutions, acetone, and even vinegar should never contact bleach because the results are harmful to your health. When using bleach, pour half a cup into the drain and let it settle for half an hour then run a lot of water to flush it down the drain.

An alternative to using bleach is the use of hot water. Flush some warm water down the sink for approximately five minutes, followed by five cups of boiling water. Mix equal amounts of vinegar and baking soda and use them to clean the drains.
