Grain Storage Chemicals in Kenya – Protect Your Harvest from Maize Weevils and Stored Grain Pests

Every year, thousands of farmers across Kenya lose a significant portion of their harvest to maize weevils, larger grain borers, grain beetles, and other stored product pests. These insects damage stored maize, beans, wheat, sorghum, rice, millet, and other cereals, leading to reduced food quality, lower market value, and unnecessary post-harvest losses.

Using the right grain storage chemicals is one of the most effective ways to protect your harvest or stored product pest control. Whether you are storing grain for home consumption, seed, or commercial sale, quality grain protectants help preserve your produce and reduce insect infestation throughout the storage period.

At PEST FLASH, we stock trusted maize storage chemicals in Kenya, including industry-leading products such as Actellic 50 EC and Actellic Gold Dust, suitable for both small-scale and commercial farming.

• Maintain grain weight
• Improve market value
• Extend storage life
• Preserve food security

Larger Grain Borers

Highly destructive insects capable of causing severe losses in stored maize and dried cassava if not properly managed.

Grain Beetles

Several beetle species attack cereals and pulses during storage, reducing grain quality and contaminating stored produce.

Flour Beetles

These pests commonly infest processed grain products and damaged kernels in storage facilities.
