Roaches are a common household nuisance that many of us have battled at one point or another. As a pest control specialist, I’ve encountered countless home remedies that people swear by.

One such remedy that’s often discussed is the use of hairspray. But does it really work? In this article, we’ll delve into the science behind this method, weigh its effectiveness, and explore other alternatives.

By the end, you’ll have a clearer understanding of whether hairspray is a friend or foe in your fight against these pesky invaders.

Does hairspray kill roaches?

Yes, hairspray can kill roaches, but it’s not the most effective or safest method. When sprayed directly onto a roach, hairspray acts as a neurotoxin, immobilizing the insect and eventually leading to its death.

However, the reason behind this is that the hairspray essentially covers the roach’s spiracles, or breathing tubes, suffocating it. It’s not a quick or humane kill.

Moreover, using hairspray as a roach killer poses risks. The residue left behind can attract more pests, and it’s not a long-term solution. Additionally, if you have pets or small children, they might come into contact with the toxic residue.

It’s also worth noting that hairspray is flammable, so using it near open flames or electrical outlets can be dangerous.

For a more effective and safer approach to roach control, there are alternative methods worth considering. In the next section, we’ll explore some of these alternatives to help you make an informed decision.

Alternative methods for roach control

We all want a roach-free home, and while hairspray might offer a quick fix, it’s not the best long-term solution. Let’s explore some alternative methods that are both effective and safer for your household.

Natural remedies and their effectiveness

Many homeowners prefer natural remedies as they tend to be safer for both humans and pets. Diatomaceous earth, for instance, is a popular choice.

It’s a fine powder that damages the exoskeleton of roaches, leading to dehydration and death.

Another option is a mixture of sugar and baking soda. Roaches are attracted to the sugar, but the baking soda reacts with their stomach acid, causing them to die.

Commercial products specifically designed for roach extermination

If you’re looking for a more potent solution, there are several commercial products available. Roach baits and traps lure roaches with a food source, then poison them.

Gel baits are another effective option, as roaches consume the gel and take it back to their nests, poisoning other roaches.

Always remember to read and follow the label instructions carefully, especially if you have pets or children in the house.

Preventative measures to keep roaches at bay

Prevention is always better than cure. Seal any cracks or gaps in your home’s foundation or walls to prevent roaches from entering.

Regularly clean your home, especially the kitchen and bathroom, to eliminate food sources and potential breeding grounds. Additionally, store food in airtight containers and fix any water leaks, as roaches are attracted to both food and water sources.


Roaches are a persistent problem in many households. While hairspray can offer a temporary solution, it’s not the most effective or safest method.

Natural remedies and commercial products provide more reliable results without the risks associated with hairspray. Ultimately, prevention and consistent efforts are key to maintaining a roach-free environment.

Choose the method that aligns best with your household’s needs and safety.
