The Drawbacks Of Using Diatomaceous Earth In Your Garden
By ELYSE HAUSER
Diatomaceous earth is a natural, effective way to keep pests away from gardens. However, this pesticide also poses some serious drawbacks that you should be aware of.
Its potency can harm both pests and beneficial insects like pollinators. When applied near flowers, these essential pollinators are particularly
at risk.
While it isn't toxic for humans, diatomaceous earth's fine, powdery composition makes it a natural irritant. It can irritate the nose, skin, and eyes upon contact or inhalation.
Moreover, diatomaceous earth loses its effectiveness in rainy or damp conditions, necessitating frequent reapplications, which increases the chances of exposure and irritation.
If you decide to buy it, choose the food-grade variety rather than the pool-grade one. The latter contains chemicals and additives that can be harmful to plants, humans, and pets.
Though food-grade diatomaceous earth offers a short-term fix, it isn't ideal for long-term use. Instead, consider alternatives, like building a basil barrier, to ward off pests.
