Are Bats the Most Underrated Pest Control on Farm?

Episode Description

Today we’re talking moths  and asking a bold question: could bats be the game‑changing IPM tool that protects harvestable yield and boosts the bottom line for this Kent dessert‑apple farm? Richard and Fraiya Chandler of Chandler & Dunn, together with Agrii agronomist Neil Obbard, have been putting this idea to the test.

Summary:

Bats as natural pest control: The farm is exploring whether boosting bat populations can significantly reduce key moth pests in apple orchards, lowering reliance on insecticides and cutting production costs.

High economic impact of moth damage: Moth species like codling moth and tortrix can cause major crop losses, and current chemical control costs the farm £500–£600 per hectare.

Scientific evidence backs the idea: A 2022 study shows that a single brown long‑eared bat can reduce crop loss by 81–83% per hectare - a remarkable potential impact. 

Habitat improvement is key: Enhancing hedgerows, tree cover, and installing appropriate bat boxes can help attract and support different bat species, boosting their presence in orchards. 

Wider farming benefits: Using bats aligns with sustainable IPM, protects biodiversity, and may translate to benefits across other crops like plums, cherries, and blueberries.
