In this article, I’ll be guiding you through the effectiveness of Raid Ant and Roach spray on spiders, not just on ants and roaches. We’ll dive into its ingredients, and how they interact with these eight-legged intruders.

Moreover, I’ll introduce you to some alternatives for spider control. By the end of this, you’ll be equipped with insights to help you make the best pest control decision for your home. Let’s get started.

Does Raid ant and roach kill spiders?

Yes, Raid Ant and Roach spray can kill spiders. The primary active ingredients in this product are imiprothrin and cypermethrin, both of which are insecticides that can also affect spiders. These chemicals act on the nervous system of insects and spiders, causing over-excitation of nerves, paralysis, and eventually death. They are not species-specific, meaning they affect a wide range of insects and other small pests including spiders.

However, it’s important to note that the effectiveness can vary. While these chemicals will likely kill a spider on direct contact, spiders are less susceptible than insects like ants and roaches.

The reason for this lies in the biological differences between insects and arachnids. Spiders, unlike most insects, have a waxy cuticle that limits the absorption of insecticides, reducing the product’s efficacy.

Additionally, spiders’ behavior makes them less likely to come into contact with the spray.

Unlike ants and roaches that scurry around on the ground and can easily cross treated surfaces, spiders often stay in webs or move across their silken threads, limiting their exposure.
In the next section, we will explore some alternative solutions for spider control that may provide more targeted and effective results.

Alternatives for spider control

While Raid Ant and Roach spray can kill spiders, there are often more effective solutions available specifically for spider control. Let’s explore some of these alternatives.

Other commercial products specifically designed for spiders

Several insecticides on the market are specially formulated to deal with spiders. These products often contain different active ingredients that are more effective against spiders, like deltamethrin or bifenthrin.

They penetrate the spider’s waxy cuticle more effectively, ensuring a higher kill rate. They may also have a residual effect, continuing to kill spiders that walk over treated areas for days or even weeks after application.

Natural and homemade solutions for spider control

If you’re not keen on using chemicals in your home, there are several natural and homemade solutions you can try. Essential oils such as peppermint, lavender, and tea tree oil have been known to deter spiders.

You can mix these oils with water and spray them around your house, especially in areas where you often see spiders.

Diatomaceous earth, a non-toxic powder made from crushed fossilized algae, is another great alternative. It’s harmless to humans and pets but lethal to spiders and other small pests. Just sprinkle it around areas where spiders frequent.

Professional pest control services for spider infestations

Sometimes, a spider problem might be too large to handle on your own. If you’re dealing with a serious spider infestation, it might be best to call in the professionals.

Pest control companies have access to stronger products and specialized equipment, and they know how to use them safely and effectively.

They can also identify and address the root causes of your spider problem, such as gaps in doors or windows or cluttered storage areas, helping prevent future infestations.

After exploring these alternatives, it’s time to wrap things up. In the next section, we’ll summarize what we’ve learned about the effectiveness of Raid Ant and Roach spray on spiders and the alternatives available for spider control.


Raid Ant and Roach spray can indeed kill spiders, though its effectiveness might be less compared to ants and roaches due to biological and behavioral differences.

For a more targeted approach, consider using products specifically designed for spiders, trying natural or homemade solutions, or hiring professional pest control services for severe infestations.

No matter what you choose, armed with this knowledge, you are now better equipped to make the best pest control decision for your home.
