What to Pour Down Drain to Kill Roaches

If you are trying to kill roaches in your house and are searching for what to pour down drain to kill roaches, then you have come to the right place. This article will explain what you need to do in order to get rid of roaches for good. In this article you will learn what to use to get rid of roaches, how to treat them, and how to seal off your house from getting cockroaches in the first place.


If you want to kill roaches, you should try using borax. This is a natural mineral that is commonly found in detergents. It is also a great repellent for roaches.

There are many ways to use borax to get rid of roaches. You can make your own roach bait, put it in sandwich bags, or add it to your pet’s food. However, if you decide to go this route, you will need to ensure you keep it away from children and pets.

Borax has the ability to kill roaches by damaging the gut lining of the roach. Once the cockroach consumes it, it will die.

Borax is also used to unclog drains. Roaches can easily crawl up drains. They prefer dark places. Therefore, you can place borax in cracks around baseboards, underneath appliances, and in small areas.

Aside from killing roaches, it can eliminate odors. You can sprinkle borax on your kitchen counters, in your toilet, and under your sink. Alternatively, you can mix equal parts of sugar and flour with borax.

Another way to kill roaches is to pour bleach down the drain. However, this can cause serious damage to your pipes. Rather than using this approach, you can put a solution of vinegar and hot water in your drain. The corrosive nature of the solution will kill roaches as well.

If you are not sure whether your solution is effective, you can try a litmus paper test. The acidity level will indicate whether it is safe to pour the solution down the drain.

When using this method, you will need to run the water for at least 15 minutes. You can also repeat this procedure a few times to make sure all of the roaches are killed.

Boric acid

If you have roaches living in your house, you may want to consider using boric acid as a way to kill them. Borax is a natural mineral, and it’s not as toxic as many of the other options available.

The process of mixing and pouring boric acid down your drain should be done with care. You don’t want to end up with a chemical smear on your walls or in your pipes. That’s why it’s important to vacuum it up first.

When using boric acid as a roach killer, you may also want to consider adding a bit of vinegar to the mix. Vinegar has antiseptic properties, so it will help you clean cooking surfaces and garbage disposals. It will also kill roaches on contact, and can be used as an effective roach spray.

Another way to kill roaches is with bleach. However, it’s not as effective as borax. Bleach can be dangerous to your eyes and skin. Also, the efficacy of bleach can be reduced if it’s left to sit for too long.

You can also use a homemade solution. Mixing some baking soda with a small amount of hot water can kill roaches. And it can be a lot faster than other methods.

If you don’t want to pour boric acid down your drain, you can try mixing a teaspoon of baking soda with a cup of water. After letting it sit for five minutes, you can dump the mixture down the drain.

Another option is to pour hot water down your drain. This method doesn’t work as effectively, but it’s less hazardous than other methods.

You can also try a solution made from ammonia and water. Ammonia is a potent roach killer, and it can be thrown down your drain. A nasty smell will be released, but it can kill roaches on contact.


When you want to kill cockroaches in your drain, you can do so by pouring down the drain a bleach solution. However, you should not do this without the supervision of a professional pest control. There are other alternatives that are safer for the environment.

One of the safest methods to kill roaches in your drain is to mix a little baking soda with some vinegar. Both ingredients are readily available. You can mix the two in a cup and then pour it down the drain. This will also eliminate any odors that are in your pipes.

Another way to kill roaches in your drains is to mix some ammonia with some water. This will make a cleaner that mixes quickly and can be thrown down the drain. The combination will produce a pungent smell and is an effective roach killer.

Using chemicals to kill roaches in your drain can cause damage to the drain system. They can also cause environmental damage and pollution of groundwater. If you decide to use chemical solutions, always wear gloves.

Alternatively, you can try boiling water. You will need to boil about two to three gallons of water before pouring it down the drain. As long as the water is hot, cockroaches will not be able to breathe.

While a combination of vinegar and baking soda may seem like a better choice, it is not as effective. The odor is not as pleasant to the roaches, and they will find other ways to avoid it.

When using a bleach-based solution to kill roaches in your drain, you should not leave it in the drain for too long. Leaving it in your pipes will cause a corrosion that will weaken the pipe.

Sealing crevices and cracks

Sealing crevices and cracks in drains to kill roaches is important to maintaining the health and safety of your family. Roaches can invade your home through small openings, causing damage to your property. They can also be a source of allergens. It is best to hire a pest control company for a thorough inspection.

There are several different types of cockroaches. The brown marmorated cockroach is found outside in sewers, mulch, tree holes, and voids in walls. These roaches are about 1 inch long and have a pale white stripe on their thorax.

Besides bringing allergens into your home, roaches are also a threat to your family’s health. When you find a cockroach, remove it from the affected area. If you find multiple roaches, it is likely that they are a breeding pair.

Roaches prefer warm, damp places to live and eat. This is why they tend to reside near the kitchen or bathroom sink drain. Cockroaches are very hardy creatures and can survive for several days without food.

Fortunately, roaches can be killed by a variety of methods. For example, you can use a caulking gun or silicone sealant to seal gaps around pipes. Another effective method is to place a granular insecticide like Delta Dust on the roaches.

To kill roaches in drains, you can apply baking soda, vinegar, or a bleach solution. Keep in mind that these chemicals can pollute groundwater. You can also purchase a liquid pesticide that can be applied using a separate sprayer.

If you do not want to use chemicals to fight roaches, try applying natural solutions to remove them. In addition to keeping your home clean, you should always check for gaps around sinks and other plumbing.

Ensure cockroaches aren’t coming up the drain

When it comes to ensuring cockroaches aren’t coming up the drain, there are a few things to keep in mind. First, roaches aren’t just a nuisance; they can also carry disease and allergens into your home.

Roaches are known to squeeze through small cracks and crevices. If you have small holes around your drains, you should consider using steel wool or duct tape to seal them up.

Another good idea is to use a liquid trap seal primer, which prevents the drains from getting dry. This will ensure roaches aren’t coming up your drain.

Aside from this, you can also use peppermint spray on your drain covers. Peppermint is an excellent repellent that will keep cockroaches from climbing your drains.

It’s also wise to regularly clean your pipes and floor. These areas are prone to build up with a thick layer of gunk. This build up is a major attraction for roaches.

You can also prevent cockroaches from coming up your drain by using an anti-roach drain protector. These are easy to install and are inexpensive.

Other methods of preventing cockroaches from getting into your drain include using metal drain screens and rubber drain covers. However, these may not be effective if the drain is in a location where the roaches can easily access it.

Also, you should try to avoid pouring chemicals down your drains. The chemicals can cause damage to plants and wildlife. Plus, they pollute groundwater.

There are also enzymatic cleaners that can be used to clean your pipes. Make sure to follow the manufacturer’s instructions.

Finally, if you want to make your own cockroach-killing potion, consider mixing baking soda and vinegar. The combination will increase the pressure in your drains
