Are Cockroaches Immune To Pesticides?

According to experts, cockroaches are becoming more and more immune to pesticides. As people who work in the pest control industry, we can confirm that this is 100% true. The unfortunate truth is that today’s cockroaches are almost completely resistant to most pesticides. But what should you know about this and what does it mean for the future of pest control?

Why have they become immune to pesticides?

Cockroaches have a reputation as one of the most difficult pests to eradicate. The reason for this is quite simple. These pests have evolved over millions of year to survive in even the harshest conditions. This is why cockroaches can do things like survive without a head, and live through radiation. This is also why they have evolved to the point where they are immune to pesticides.

There’s also another interesting reason why this has happened. According to scientists, it’s because cockroaches only live about 100 days. What this means is that this resistance can evolve extremely quickly. It also means that these pesticide resistant cockroaches can pass their genes on to future generations. Ultimately, this means that cockroaches may be impossible to treat with pesticides in the future. But if cockroaches are immune to pesticides, then how do you get rid of them?


So, what does get rid of cockroaches?

The answer is something that pest controllers call “integrated management.” This is basically an approach which uses a number of pest eradication techniques. First of all, in some cases pesticides may actually work, so they are still used. Along with that there are chemicals which repel these pests.

Integrated management also involves setting traps and vacuuming the cockroaches up for a pest free home. Something else which is now being extensively used are heat treatments. This method does not use any chemicals, which is great because it means that cockroaches cannot build up an immunity.

Another important facet of this approach is hygiene. This means keeping the area spotlessly clean. The idea is that if you take away the cockroaches’ food source, they may eventually leave and put an end to cockroach allergies.


The bottom line is that while cockroaches are becoming immune to pesticides, is doesn’t mean that they will beat us. These pests can be eradicated with enough effort. That being said, you will probably need help. Yes, keeping a cleaner house will help, but as you have seen, shop bought cockroach poison will do nothing.

This is why it’s so important that you get a local pest professional on the case as soon as possible. The longer you wait the harder it is to eradicate these pests. We have the tools, knowledge, and experience needed to eliminate them. Not only that, we can do it a lot faster than most people think.
