Understanding Diatomaceous Earth

Although diatomaceous earth may sound like it belongs in a science fiction film, it is actually pretty straightforward. Diatoms are ancient marine organisms that left behind small fossilized skeletons. The powdery texture we get from handling these fossils is a good analogy for how tiny they are. However, even miniscule fragments can cause serious injury to little creatures. Insects and spiders can have their exoskeletons sliced apart by these points, leading to dehydration.

The best thing, though? People and animals alike won’t be harmed. That means you can safely use it around your house, without concern for the safety of your pets.

Common Household Spiders

Let’s discuss spiders right now. Everyone has experienced the horror of discovering a spider camped out in a dark nook of their home. Most spiders we see in our homes are harmless, despite their ability to frighten us. The typical house spider, which prefers to lurk in the shadows, and the long-legged cellar spider are both possibilities. Although spiders have a reputation for being creepy, it’s important to keep in mind that they’re normally just going about their day and trying to catch other pests in their webs. It’s fine if you want to have them around, but diatomaceous earth can help if you don’t want to.

Does Diatomaceous Earth Kill Spiders?

Is diatomaceous earth effective in preventing spiders from leaving? To put it simply, yeah. Like other little insects, spiders can be harmed by the tiny, pointed fossils we discussed before. Diatomite earth’s sharp particles slash into spiders’ exoskeletons as they crawl through it, eventually leading to dehydration and death. Therefore, diatomaceous earth is a reliable option if you’re seeking for a natural method to dissuade spiders from settling in.

How to Use Diatomaceous Earth for Spider Control

The process of applying diatomaceous earth is simple. To get rid of spiders, just dust a light layer along the baseboards, in the corners, and around the windows. Place the powder in an area where spiders are likely to wander so that they will be exposed to it. Keep in mind that “a little goes a long way”, so there’s no need to go crazy.

Safety Considerations When Using Diatomaceous Earth

Diatomaceous earth is non-toxic to people and animals, but it should be used with care nonetheless. Dust can irritate your lungs and should be avoided at all costs. If you’re dusting a large area, it’s probably a good idea to wear a mask when using it. It’s harmless for pets, but avoid letting them ingest or breathe in too much of it.

Conclusion

To eliminate spiders, you need not resort to using poisons. Diatomaceous earth is a non-toxic, all-natural product that may be used to successfully and safely get rid of spiders and other small pests. Why not try it then? Get rid of those pesky spiders and welcome in a more tranquil, spider-free environment.
