For decades, pest infestation has been one of the biggest threats to farmers, causing billions of dollars in losses annually. Traditionally, the solution has been heavy pesticide use, a costly practice that often harms ecosystems and farmer health. But a new wave of innovation is showing there’s a smarter way forward in the form of AI and IoT pest control.

Meet Spotta: AI + IoT for Early Pest Detection

UK-based agritech startup Spotta is pioneering a system that uses IoT sensors and artificial intelligence to detect pests at an incredibly early stage.

🔹 How it works:

• Smart IoT “pods” are placed in the field or greenhouse.

• They monitor insect populations 24/7, automatically identifying pests using AI-driven image recognition.

• Farmers receive instant alerts via app when target pests are detected.

By catching infestations at the earliest possible stage, Spotta empowers farmers to act precisely—treating affected areas only, instead of blanketing entire fields with chemicals.

Why This Matters for Farmers

• Reduced Pesticide Dependence: Farmers save money on chemicals while protecting soil, water, and biodiversity.

• Higher Yields: By stopping infestations before they spread, harvest losses shrink dramatically.

• Sustainability Gains: Precision pest control supports healthier ecosystems and contributes to global climate-smart farming goals.

Imagining the Impact in Ghana

Now imagine systems like Spotta being deployed for Ghanaian staples such as maize, cowpea, and sorghum, all crops highly vulnerable to pest attacks.

📌 The Fall Armyworm, for example, has devastated maize farms in Ghana since 2016, with farmers often spending up to 15–20% of their costs on pesticides. Early detection with AI and IoT could:

• Prevent mass outbreaks before they cripple harvests.

• Cut farmer expenses on chemical sprays.

• Make grain safer and healthier for both farmers and consumers.

The Bigger Picture

AI and IoT are no longer “future tech”, they’re here, reshaping agriculture from pest control to soil testing. By integrating such systems into Ghana’s agritech ecosystem, we can reduce losses, protect farmers’ incomes, and move closer to food security.

Bottom Line

The fight against pests doesn’t have to rely solely on pesticides. With AI-powered, IoT-enabled solutions like Spotta’s, agriculture is entering a new era where prevention replaces reaction.

At Sesi Technologies, we’re excited about innovations like these and their potential for Ghanaian agriculture. Imagine pairing early pest detection with our GrainMate Moisture Meter and ZeroFly Hermetic Bags, a full chain of protection from farm to storage. That’s how technology creates lasting impact.
