The question now is; will bleach serve as a roach killer?

It does kill roaches.

This is evident when they’re drowned in it, they hardly survive.

Plus, when ingested by roaches, bleach will definitely take its toll by poisoning them. However, it’s clear that drowning roaches or having them ingest bleach isn’t practical or effective.

A more reliable treatment alternative is needed. Thankfully, there’s never a lack of effective treatment alternatives as shown below.

It begins with the best method which is prevention.


You don’t have to wait to experience roach issues before taking action. It’s best to adopt a preventive approach. Such proactive action seeks to keep your home roach-free.

Basically, you’ll need to step up your hygiene practices such as eliminating food sources and decluttering.

Other preventive measures include cleaning, as well as maintenance or sealing of entryways. To help you better understand, let’s consider each of these points as follows;

i. Eliminating Food and Moisture Sources

Whenever you find roaches around your home, they’re attracted to food sources as well as moisture. These pests will readily feed on leftovers, food crumbs, spilled beverages, and just about anything they can find in your bin.

You’ll also need to look out for moisture sources as these pests love to hang around moist areas. You’re likely to find them hoarded around damp spots.

You’ll need to identify the leaky pipes around such areas and have them fixed.

ii. Properly Store Food

How well do you store your food? Have perishable food stored in your refrigerator while grains and processed food can be emptied into airtight plastic containers.

Any leftovers should either be properly stored in a fridge or disposed of.

iii. Do Your Dishes Before Going to Bed

To keep roaches at bay, consider doing your dishes before going to bed.

Also, the sink and countertops should be wiped clean to eliminate all possible sources of food that could serve as an incentive for roaches.

iv. Consider Emptying Your Bins More Regularly

Keeping bins for too long without emptying is a sure recipe for roach presence. It’s best to have such emptied at the end of each day. Never leave such sit overnight as these pests are mostly nocturnal feeders.

v. Removing Clutter

The more clutter you have around your home, the higher the possibility of roach presence.

As a matter of fact, when roaches find ample clutter around, they mark such regions with pheromones to serve as an attraction to their kind. Before long, your home becomes overrun with their presence.

So, what can be considered clutter? Pretty much anything lying around with no clear use benefit! These range from old magazines, packaging, old newspapers, and cardboard among others.

vi. Cleaning

Cleaning is one effective roach preventive measure that can be easily implemented.

Here, you want to clean all food spills, crumbs, dishes, and anything food-related they might become attracted to. The kitchen and dining areas are places you should target more for cleaning.

vii. Maintenance

Maintenance involves a wide range of actions such as fixing drains and pipes, sealing of possible entrances, and also fixing or repainting shelves.

The moisture in drains and pipes seems to be the major attraction for roaches. These pests flock there to also feed on food sources found within such areas.

You’ll need to clean your drain more often and have all broken pipes replaced or properly sealed.

Apart from drains and pipes, other possible hiding spots used by roaches include wall cracks, skirting boards, underneath kitchen sinks and bathroom cabinets.

Have these areas maintained to keep these pests at bay?

Place Gel Baits

With bleach out of the question as an effective roach killer, you might want to try gel baits. Have these bait stations placed at strategic points? Areas, where these pests are most attracted to, are targeted.

Before long, you should be able to contain their spread and take back control of your home.

Boric Acid

One home remedy to try out is boric acid. This is best used in conjunction with other pests. When they come in contact with or ingest boric acid, it becomes toxic to them, thus leading to their death.

Have a Pest Management Professional Help Out

Carrying out DIY roach extermination using assorted methods isn’t as effective as professional treatment.

It’s easy to see why. Trained professionals are knowledgeable about roach behavior and know just what to do to contain an existing infestation no matter how severe.

All you have to do is give them a call to come over to inspect and carry out comprehensive treatment of your home.


Bleach indeed kills roaches. These critters can be overwhelming when there’s a full-blown infestation. But such a situation can be brought under control by using readily available alternatives like bleach.

The downside to its use is the challenge posed by the fast movement of adult roaches.

Another is the fact that these pests are largely nocturnal. So, it’s unlikely that you’d find them during the day.

We’ve established the fact that bleach kills roaches. But the “how” is a bit challenging. You may think of making a bleach recipe to control roaches but this too has its limitations.

This is because roaches will hardly feed on any bait that has a bleach odor. They won’t also drink cups of bleach kept in the open. Plus, this poses a health risk to pets and kids.

The logical way to use bleach effectively on roach is by the use of the spray. This too has its health risks as you’d have to deal with chemical fumes given off during the process.

Roaches are found around pipes and sinks due to water availability. They may nest in drains or pipes.

To get rid of roaches, pour a cup of bleach down the pipe or drainage. This should be followed immediately by several cups of water. It kills them within a short time.

Bleach will kill roaches but is never an effective remedy against such pests. We’ve provided several other alternatives to try out to contain the problem.
