When it comes to keeping your home clean and free from pests, most people immediately think of chemical pesticides and harsh treatments. However, what if we told you that a simple household item like baking soda could be the key to solving your bug problems in a natural, eco-friendly way? Yes, that’s right—baking soda isn’t just for baking; it’s an incredibly effective solution for eliminating insects, bugs, and even cockroaches.
How Baking Soda Works Against Insects and Bugs
Baking soda, or sodium bicarbonate, is a versatile compound that has a wide range of uses. From cleaning to deodorizing, it can do it all. But what makes it so effective against pests is its ability to disrupt the biological functions of insects and bugs.
Here’s how it works:
-
Desiccation Effect: Many pests, such as cockroaches, ants, and other crawling insects, have an exoskeleton that is sensitive to dehydration. Baking soda acts as a desiccant, drawing moisture out of their bodies. When bugs come into contact with baking soda, it dries them out, leading to dehydration and eventual death.
-
Toxicity to Insects: Baking soda is harmless to humans and pets, but it’s lethal to pests. Insects often consume baking soda unknowingly when they come across it while foraging. When they ingest it, the baking soda reacts with the acid in their stomachs, causing a gas buildup that is lethal to them. It disrupts their digestive system, and they die as a result.
Types of Bugs and Insects Affected by Baking Soda
Baking soda is a versatile pest control solution and works against many common household pests, including:

-
Cockroaches: These resilient creatures are notorious for infesting homes. However, baking soda can be one of the most effective natural methods for exterminating them. Simply sprinkle a little baking soda in areas where you’ve seen roaches, and it will quickly dehydrate and kill them.
-
Ants: Ants are another common household pest that can be difficult to control. They are often attracted to sugary foods and crumbs, and baking soda can be used to repel them. When ants consume baking soda, it disrupts their internal systems, causing death.
-
Silverfish: These tiny, silver-colored bugs are known for infesting areas of the home like bathrooms and basements. Baking soda can be sprinkled around areas where silverfish are spotted to eliminate them naturally.
-
Bedbugs: While more challenging to eradicate, a combination of baking soda and other natural ingredients can be used to target bedbugs. By sprinkling baking soda in the cracks of your furniture and bed frames, you can suffocate and kill these pests.
-
Fleas: Fleas are a common problem for pet owners, but baking soda can help reduce their numbers. By sprinkling baking soda onto your carpets, letting it sit for several hours, and then vacuuming it up, you can kill fleas and larvae.
-
Mites and Other Small Insects: Mites, which are tiny and difficult to see, can cause discomfort and irritation. Baking soda can be an effective treatment for mite infestations as well. Its drying properties help eliminate these pests.
How to Use Baking Soda to Get Rid of Pests
Baking soda is incredibly easy to use, and the best part is that it’s completely natural and safe for your home. Here are a few simple ways to use it to eliminate insects:
-
For Cockroaches and Ants:
-
Sprinkle a light dusting of baking soda in areas where cockroaches and ants are commonly found, such as in cracks, crevices, and along baseboards.
-
You can also mix equal parts baking soda and sugar to attract ants and cockroaches. The sugar draws them in, and the baking soda works to eliminate them once ingested.
-
-
For Silverfish:
-
Place small piles of baking soda in areas where you’ve noticed silverfish, such as behind furniture or in closets.
-
Alternatively, create a mixture of 2 tablespoons of baking soda and 1 teaspoon of borax, and sprinkle this around your home. It works by drying out silverfish and other pests.
-
-
For Fleas:
-
Sprinkle baking soda directly on your carpets and pet bedding. Use a broom or brush to work it into the fibers. Let it sit for several hours or overnight before vacuuming it up.
-
This method not only kills fleas but also helps neutralize odors in the process.
-
-
For Bedbugs:
-
Apply a thin layer of baking soda along the seams of your mattress, bed frames, and any cracks or crevices where bedbugs may hide. Leave the baking soda overnight, then vacuum it up the next morning.
-
-
For Mites:
-
Sprinkle a small amount of baking soda onto any area where mites are present. This includes pet bedding, furniture, or other infested areas.
