Introduction
In 2025, more Kenyan farmers and homeowners are switching to diatomaceous earth Kenya as a safe, affordable, and effective alternative to chemical pesticides. Whether you’re storing maize, managing poultry parasites, or tackling bedbugs at home, this natural powder offers versatile protection. In this guide, we explore the uses, benefits, safety tips, and where to buy it across Kenya.
What is Diatomaceous Earth?
Diatomaceous earth (also called diatomite) is a naturally occurring soft, siliceous rock made from fossilized aquatic algae known as diatoms. When crushed into a fine white powder, it works as a mechanical insect killer — drying out pests without using toxic chemicals.
It’s widely used across the world and is gaining popularity in Kenya due to its organic nature, affordability, and versatility.
Also known locally in some areas as “Kariandusi diatomite” (from the famous mining site in Nakuru County), it is available in both food-grade and industrial-grade forms.
Why Use Diatomaceous Earth in Kenya?
Kenyans are embracing diatomaceous earth Kenya due to rising awareness of pesticide-related health issues and growing demand for organic farming. Here are some key reasons:
- Safe for humans and animals when applied correctly
- No risk of chemical residues in food
- Affordable and accessible via local agrovets and online shops
- Effective against common pests like weevils, cockroaches, bedbugs, aphids, mites, and even poultry mites

Top 6 Uses of Diatomaceous Earth in Kenya
1. Farm Pest Control
Diatomaceous earth Kenya is highly effective against soft-bodied pests like aphids, red spider mites, and fall armyworm. Sprinkle the powder directly onto leaves, stems, and soil.
Tip: Apply early morning or late evening to avoid blowing away during wind.
2. Grain Storage Protection
In post-harvest storage, especially for maize and beans, mixing diatomaceous earth into the bags keeps weevils at bay.
Apply 1kg of DE for every 90kg of maize for effective long-term storage.
3. Poultry and Livestock Care
Farmers use diatomaceous earth in chicken coops and goat sheds to control mites, ticks, and lice. It also helps as a natural dewormer when mixed (in small doses) with animal feed.
4. Home Pest Control
For homeowners, DE is a safe weapon against bedbugs, ants, and cockroaches. Dust along baseboards, bed frames, and dark corners. It works mechanically—no poison, no smell.
5. Soil Amendment
As a soil conditioner, diatomite improves aeration, retains water, and releases silica into the soil. Useful for horticulture, potted plants, and flower farming.
6. Garden Pest Management
DE acts as a companion planting powder for tomatoes, sukuma wiki, and cabbage gardens, especially in organic shamba systems.
How to Apply Diatomaceous Earth Safely and Effectively
- Wear a dust mask when applying — DE can irritate your lungs if inhaled.
- Reapply after rainfall or watering, as the powder loses effectiveness when wet.
- Use a dust sprayer or shaker bottle for even application.
- Keep out of reach of children and pets until settled.
