With all the rain we’ve been having in Oklahoma they are flourishing like a giant mob of tiny monsters taking over the garden. They are sliming the lettuce, chomping the strawberries, mangling the seedlings, and being a general menace! Other than squash bugs, I hate slugs the most!

My Little Sprouts and I worked too hard toiling over planting this yummy food just to feed it all to the nasty slugs! UGH!

That’s where diatomaceous earth comes in. It’s a great natural product which is actually made of ground up ocean fossils! Diatomaceous earth works when you sprinkle it around your garden surfaces in a fine layer. When pests crawl over it, it cuts the waxy coating on their underbellies and causes them to dehydrate and die.

How to get rid of slugs in the garden

Diatomaceous earth will help you get rid of slugs in the garden as well as several other pests including slugs and the nymphs or babies of the squash bug. It is even effective against roaches. When you use diatomaceous earth, sprinkle it on in a superfine layer like the dust on your furniture for the most effectiveness.

Wanna garden but you need the basics?

Diatomaceous earth does not work instantly, it handles the problem over time. It takes several days for the pests to dry out. Diatomaceous earth must be applied to dry surfaces in order to be effective. Once it rains, you need to reapply it. It helps stop slugs in the garden more quickly than other pests because it dries them out. 

It’s also good to try to sprinkle it on the underside of your leaves as well as the tops. If you want to read more about other uses for Diatomaceous earth, click here.

Another great thing about diatomaceous earth is it is safe for human consumption. You can sprinkle it right on your food crops and it will not harm you in the least if you ingest it.

I make sure to use food-grade diatomaceous earth so I don’t have to worry about its residue being on my food. In fact, many people take it regularly for their health. 

Using diatomaceous earth in your garden for pest control keeps it natural and chemical-free. When you wash your produce as you normally would, the diatomaceous earth is rinsed away.

Be careful not to rub your eyes with diatomaceous earth on your hands because it can scratch them. You also don’t want to inhale the dust as it could irritate your lungs. Use common sense when applying and storing any product.

The only downside I have found to using Diatomaceous earth is it does not discriminate and can harm bees. If you sprinkle it on flowering crops, you can cover them with a row cover so bees won’t approach them to pollinate. That will eliminate this problem. You can also apply diatomaceous earth in the late evening when bee activity decreases. Avoid putting it near the flowers where bees visit and you should be fine.
