4 Tips for Keeping Bugs Out of the Septic System – Cummings Termite and Pest Fountain Hills

Septic tanks and systems need to be cleaned up and pumped out on a regular basis if they are to function properly. It is also critical that you attempt to keep pests out of your septic tank, since they are a regular occurrence in these systems. Some pointers for keeping pests out of your septic system are provided below.

1.Pour Bleach Down the Drain

Pouring a large number of different chemicals down the drain is not a safe practice. For those who have septic systems, a modest dose of bleach should be sufficient. This will aid in the cleaning of the pipes and the septic tank, which will in turn assist to lessen your bug infestation. The usage of bleach is quite beneficial, whether you currently have a problem with drain flies or you wish to avoid pests completely. Several bugs are attracted to the sludge and trash that ends up in the septic tank.

The usage of bleach is quite beneficial, whether you currently have a problem with drain flies or you wish to avoid pests completely.

2.Clear Clogs Immediately

However, it is possible that the bugs are not attracted to the septic tank at all, but rather to the amount of detritus caught inside the pipes itself. This can become a greater problem inside your house since the trash may entice them into your plumbing fittings, where they can cause damage. Ensure that you clean any clogs from your sink or shower drains as soon as possible if you have a slow-running or clogged drain. If you are unable to clean them out on your own, you should contact a plumber to assist you.

3.Have the Tank Pumped Regularly

It is necessary to empty the septic tank on a regular basis since the wastewater, which goes into your drain field, contains waste until it is pumped. The longer the trash is allowed to lie in the tank, the greater the number of bugs it will attract. This is only one of the many reasons why it is necessary to get your septic tank drained on a consistent basis. Contact your plumber to determine the frequency with which it should be cleaned in order to keep pests at bay.

4.Fumigate the Septic Tank

When you already have insects, rodents, and other pests in your septic tank, it is necessary to take more serious measures to rid your system of the problem. In this situation, fumigating the area is frequently the best solution. The use of fumigation will aid in the elimination of any bugs that may be present in the tank. These pests might include rats, cockroaches, ants, or drain flies that have been trapped within the building. Depending on whether the pests have made their way into your home through the drains, you may also need to fumigate the interior of your home.

Please get in touch with us to discuss fumigation and the best choice for you. Keep these considerations in mind if you have a septic system and wish to keep pests out of your system. It will keep your home clean and will help to limit the amount of pest infestation on your property.

Sewer Cockroaches: Stuff of Nightmares

When the Arizona sewer roach emerges from the muck of sewers and begins to infest houses and apartments throughout the state, it is a repulsive, trouble-making, knee-quaking monster of an insect. As a result of the fact that few people outside of the state have ever heard of them, some believe they are a homegrown horror. However, this is not the case. In fact, it turns out that sewer roaches are the exact same American cockroach species that infests a wide range of different areas across the United States.

Arizonians, like everyone else who has to deal with American roaches, are desperate to get rid of them, which we’ll teach you how to accomplish in a moment.

What Sewer Roaches Look Like

Rattlesnakes, sometimes known as sewer roaches, are about 1 12 to 2 inches in length and are quite flat. They have a body that ranges from reddish-brown to dark brown in color, six legs, and two long antennae. Their robust exoskeletons make them tough to squash, yet they are also able to glide through microscopic holes due to their flexibility. They are accompanied by a pair of long, translucent wings that they wear on their backs. Despite being large bugs, they are quick runners and very adept at surviving the many methods by which people attempt to kill them.

And by the way… do sewer roaches fly?

In Arizona, when you ask a local for advise about sewer roaches, the response you don’t want to hear is anything along the lines of “Have they flown at you yet?” Yes, these monsters of the abyss are capable of flying—at least for a few feet when they spread their long wings on their backs.

Despite the fact that they normally flee when they are seen, there is a risk that they will fly directly at you! Despite the fact that they are merely attempting to flee via the door behind you,

Baby sewer roaches

The fact that baby sewer roaches are so little does not make them any less lethal. Despite their small size (approximately 1/4 inch long), baby cockroaches are the same reddish-brown hue as their larger counterparts. It is possible for them to seem white or gray right after they have molted, though. If the sewer roaches have begun multiplying, it is imperative that you act quickly.

Why You Keep Finding Sewer Roaches in Your Bathroom, and Why You Have to Get Them Out

An outdoor sewer roach’s favorite habitat is damp, decaying debris on forest floors, as well as alleys and sewers, according to the CDC. In the unfortunate event of heavy rains or a clogged sewage line, these bugs may be able to crawl up sewer pipes, drain pipes, and even up through the sink or floor drain. They are looking for wet, dark, moist spots in the house, such as kitchen cabinets, utility closets, basements, and so on. Because your bathroom is immediately connected to the sewer system, it’s common for homeowners to notice roaches and cockroach infestations in their bathroom initially.

Even sewer cockroaches will not be able to enter your home through the toilet.

At the very least, you’ll be safe on the toilet seat as long as the tank is filled with water.

Why you really need to get them out

The same reason you don’t want sewer cockroaches crawling about your house is the same reason you don’t want them living brazenly in the sewers: they eat down there. Consider all of the items that make their way into sewers on a regular basis. Beyond the “number one’s” and “number two’s,” they feed on sludge and grease piled high, as well as water overflows and other sources of food waste. When they eventually do make it inside your house, they don’t leave behind all of the potentially harmful germs, bacteria, and allergies that they brought with them.

In order to avoid a sewer roach infestation, you must act quickly, especially if the situation is becoming worse.

1. Place glue traps to find their entry points

For a sewer cockroach infestation to be successful, you must first determine where the cockroaches are entering the building. Sticky glue traps should be placed in corners and along the walls of various rooms. Check which traps have captured the most roaches in order to narrow down the region you’re targeting. Aside from kitchen sinks, bathroom sinks, and shower drains, the most common entry sites for sewer roaches are heating or utility vents, plumbing penetrations, and fractures in external walls, among other places.

2. Apply a gel bait to kill a sewer roach colony inside

A excellent cockroach gel bait is an unrivaled sewer roach killer in terms of effectiveness. Cockroaches are killed by gel bait after they have consumed it and returned to their nest. Other cockroaches will be exposed to the poisons in this area, and this is where gel bait excels. Second- and even third-hand consumption of its pesticide will result in the death of the roaches who consume it. The use of a few drops of gel bait can be quite effective against a sewer roach infestation.

3. Treat your drains

When it comes to sewer roaches, no other method compares to a goodcockroach gel bait. Cockroaches are killed after they have consumed the gel bait and returned to their nest. Other cockroaches will be exposed to the poisons in this area, and here is where gel bait excels the most.

Second- and even third-hand use of its pesticide will result in the death of any roaches that consume it. If you have a sewer roach infestation, even just a few drops of gel bait can cause significant harm.

Use a foam cleaner—cautiously

Remove any traces of food and grease that may have been left behind with a foam cleaner or similar solution to deter roaches. Read the labels ahead of time to ensure that you are aware of any precautions and correct usage.

Use bleach—cautiously

The use of chlorine not only cleans and disinfects your drains, but it also kills any roaches that may be lurking there. If you have a septic system, you should avoid using bleach, and you should never mix it with ammonia, vinegar, rubbing alcohol, acetone, other cleansers, or pesticides (which combined with bleach could harm you). Pour 1/4 to 1/2 cup of bleach down a drain and block it up to treat a clogged drain with bleach. Allow it to stay in the drain trap for 30 minutes before flushing it out thoroughly with water to remove the residue.

Use water—liberally

This is the simplest and, in some cases, most successful tactic of them all. Running water down your drains on a daily basis keeps drain traps full and prevents roaches from creeping up your drains.

4. Kill Sewer roaches naturally

Alternatively, if you’d prefer to stay away from chemicals, there are two completely natural and simple-to-use alternatives: Borax and diatomaceous earth (DE). Please keep in mind that, despite being natural, both of these products are irritants and should not be breathed. Borax combined with a little amount of powdered sugar works in the same way as gel bait, attracting sewer roaches and killing them after they have been attracted. Many retailers sell it in the laundry section, which is easy to discover.

DE is another another powerful insect killer for sewers.

Walking through DE is enough to kill cockroaches because it dehydrates them.

5. Call Professional Pest Control

If you have any reason to be concerned about a sewer roach infestation becoming out of hand, contact a pest control specialist right once. You can explore treatment choices and learn more about what might be causing the problem if you have an appointment with a medical practitioner.

How to Get Rid of Sewer Cockroaches Step 2: Preventing Them from Coming Back

The first step is to get rid of any sewer roaches that have already taken up residence. The next and equally crucial measure is to keep them out of your home. Here’s what you can do to keep sewer roaches at bay:

1. Block the drains.

First and foremost, make sure you have drain covers for every sink and bathtub in the house before proceeding. Drain stops don’t have to be anything spectacular to accomplish their job. They only need to have openings that are tiny enough so that roaches cannot squeeze through them.

2. Check the perimeter of your house and seal openings.

Drainage pipes accumulate condensation, and the moisture from this condensation can attract sewer roaches on the ground nearby. If there are any holes where these pipes enter your home, fill them with expanding foam or steel wool to keep them from leaking. Additionally, patch any other cracks or holes you notice in the walls, doors and windows, and foundation.

3. Fix leaks and dripping faucets.

Before sewer roaches establish themselves at home drinking from that irritating leaky sink in the middle of the night, have the leak repaired (and save yourself money on the water bill).

Fill the overflow holes in your bathroom sinks with some of the steel wool you have leftover from other projects.

4. Wash the dishes and clean the garbage disposal.

It’s possible that the sewer roaches didn’t actually climb up through the pipes, but are merely dipping their heads in for a nibble. Over time, your trash disposal accumulates a substantial amount of oil and food particles, providing a wonderful feast for a hungry roach. Make certain that you clean it on a regular basis. Dishes that are left dirty might also provide a food source for these bugs. Every day, washing dishes and giving the counters and floors a quick wipe-and-sweep is a simple routine that decreases the likelihood of cockroaches becoming attracted to your home.

Roaches in septic system

In addition, roaches do not swim under water at all! So, as previously said, if they are entering through the septic system, you are most likely dealing with a plumbing malfunction. Because it is extremely unusual for roaches to enter through a plumbing vent, the likelihood that one will get on the roof, climb up the exterior of the pipe, back down the pipe to the drain, and then inside the house is virtually nonexistent. They go in by accident through the garage door. They enter through open doors and windows, as well as sliding doors at the point where the two sections meet.

If they get in, they will either drown or go into the water.


This insect crap is poison, and if it weren’t, bugs would not be killed by “spraying” the stuff in the house. Treat the garage and the area surrounding all access points OUTSIDE the home with a RESIDUAL insect spray to keep the bugs away. If they manage to get in, they will perish quickly!

Can Nibor-D be flushed down the toilet to control cockroaches in septic tank?

«See More Q & A’s» writes Jorge from Miami, Florida.


If you have cockroaches that are truly coming from your septic tank, the most pressing worry you will have is identifying the spot in the tank, lid, or septic pipes that has a fracture in it that is allowing the roaches to get into your system. In your house, they would not go down your drains and establish a colony or population within your septic tank or drainage system. Because they would have gotten access through the yard/lines, the situation is likely to remain if the source is not identified, closed off, or otherwise resolved.

Nisus recommends mixing around 5 scoops of Nibor D in a gallon of water and flushing down approximately 12 gallon of solution each toilet and approximately 1/3 gallon of solution per drain, according to the company.

Will Drain Gel help eliminate roaches coming up the drain, or should I use a roach pesticide?

«Read More Q» As A’sJim from Delray Beach, Fl comments, “I, too, am connected to a septic system.” Is it possible for roaches to reside in septic tanks and then make their way up the drainage system?


Drain Gel will not treat your plumbing pipes for roaches, unfortunately. It is intended to treat the organic debris that accumulates in your drains over time, which is the source of the drain flies’ infestation. Roaches may reside in a septic tank and can enter the house through the plumbing pipes and make their way down the drains to the outside. You would not be allowed to apply an insecticide in the drains themselves, on the other hand. Gentrol Aerosol IGR is an insect growth regulator that may be used in drains to interrupt the reproduction cycle of roaches.

Keep in mind, as well, that roaches frequently simply fall into or crawl into sinks as a result of the water there, rather than really coming up via the drains.

What To Pour Down The Drain To Kill Roaches?

You now know what sorts of roaches are in your drains and why they crawl out of your drains. It’s time to put an end to this problem. Read on for more information. Fortunately, you may do the task without the assistance of a pest control professional. Perhaps you already have the three items you’d need to pour down the drains in order to kill the roaches in your home. So, here are the three items you should pour down the drain to kill roaches: – baking soda, bleach, and vinegar

  1. Bleach, baking soda, white vinegar, and ammonia cleanser are all good options.

Pour Bleach In The Drain To Kill Roaches

Cockroaches are killed quickly and effectively by bleach. It also works as a drain unclogger, which is a bonus! And it’s most likely laying around in your house right now. In the bathroom drains, the bathtub drain, and the sink drains in your kitchen, laundry room, and basement, pour half a cup of bleach and let it sit for 15 minutes. Allow for a maximum of 15-20 minutes of resting time. Bleach is quite corrosive. Allowing it to sit in the drains for more than 20 minutes might result in damage to the drain pipes itself.

As a result, you have not only killed all of the sewer roaches that were lurking in the sewers, but you have also unclogged the drains as well.

The direct touch with bleach with your skin might be harmful to your skin.

Pour A Mixture Of White Vinegar And Baking Soda In The Drain To Kill Roaches

A solution made from vinegar and baking soda is an excellent substitute for bleach. In a cup, combine the baking soda and white vinegar in equal parts by volume. Make sure to thoroughly combine the ingredients. Pour the solution down the drains. Allow the mixture to rest for no more than 5 minutes. In order to provide one final blow, pour boiling water down the drains. That will get rid of all of the roaches that are lurking in the sewers. You may also add salt to the mixture if you want to give it a little more punch.

Pour A Mixture Of Ammonia And Hot Water In The Drain To Kill Roaches

Ammonia is another another effective roach killer. Ammonia cleanser is water-soluble, and it dissolves quickly when it comes into contact with water. Equivalent volumes of water and ammonia cleanser should be combined in a bucket. Pour the liquid down the drains to kill the roaches as well. Roaches are likewise killed by ammonia when they come into contact with it. Using a spray bottle, apply the mixture to roaches if you want to manufacture your own DIY roach spray. And squirt it immediately on any roaches that you happen to encounter.

Using an anti-roach drain protector will ensure that all drains in your home are protected, including shower drains, bathroom sinks, bathtub sinks, and sink drains.

Don’t allow your drains become clogged for days on end.

Should You Pour Borax Down The Drain To Kill Roaches?

Mixing borax with water may reduce its effectiveness even further, and on top of that, the roaches may not be able to absorb it.

How to Stop Cockroaches from Coming up the Drain?

Cockroaches are extremely resilient creatures. To keep roaches from crawling up your drain, you must first understand where they are coming from. Follow the connection of your drain and try to determine where the problem originated. Depending on the situation, the main septic tank or a leak in the drain lines might be to blame. If there is a leak, seal the entry place with cement or duct tape to prevent it from leaking farther. If you suspect that the main septic tank is the source of the problem, you should contact a professional immediately since dealing with septic tanks is quite risky.

Eliminating Water Sources and Entry Points

The most important commodity for any living organism is water, which is required for survival. When you eliminate all of the water sources in your drain, the cockroaches will find the dwelling conditions in your drain to be difficult to tolerate. Standing water has a tendency to draw these animals in. As a result, you must plug all of the holes and spots where stagnant water collects. Duct tape can be used to seal gaps around pipes, while silicone or even cement can be used to seal bigger fractures.

Maintaining Cleanliness

The first step is to create an environment that is intolerable for roaches to live in. However, if you do not keep your surroundings clean, all of your efforts will be in naught. All appliances, surfaces, and even utensils in close proximity to drains should be kept clean at all times.

The impact continues indefinitely, and the infection eventually spreads to all of the roaches. Other cockroaches will infest the space created by this procedure, thus it is not recommended. Where to Look for a Roach Nest
