What are the common pests in coffee farming?
The most common and destructive pest in coffee farming is the coffee berry borer (CBB), a small beetle that bores into the to lay eggs, damaging the bean inside. Other significant threats include coffee leaf rust, a fungal disease, and various nematodes that attack the root systems, all of which can severely reduce crop yields and quality.

Coffee farming is a constant battle against nature. Because coffee is grown in tropical climates, it is susceptible to a wide array of pests and diseases that thrive in the same warm, humid conditions as the coffee plant. Among these, the coffee berry borer (CBB) is arguably the most notorious. This tiny beetle is capable of devastating an entire harvest by burrowing into the cherry, where it feeds and reproduces, leaving behind damaged, low-quality beans that are often rejected by specialty buyers.
Beyond the CBB, farmers must contend with fungal threats like coffee leaf rust. This disease attacks the leaves of the plant, preventing it from photosynthesizing effectively and eventually leading to the death of the tree if left untreated. In some regions, nematodes—microscopic worms that live in the soil—pose a silent threat by attacking the root system, which weakens the plant's ability to absorb water and nutrients. These pests and diseases are not just a nuisance; they are a major economic threat to farmers, particularly smallholders who may lack the resources for expensive treatments.
Climate change is further complicating this issue. As temperatures rise and weather patterns become more erratic, pests are migrating to higher altitudes where they were previously unable to survive. This forces farmers to adapt their agricultural practices, often by planting more resilient varieties or implementing integrated pest management strategies that rely on natural predators rather than chemical pesticides. These efforts are essential for maintaining the long-term viability of coffee production.
For the reader, the impact of these pests is felt in the cup. A crop affected by the coffee berry borer will often have a distinct, unpleasant "stink" or "potato" defect that ruins the flavor. By supporting farms that prioritize healthy agricultural practices and biodiversity, consumers play a role in helping farmers combat these threats. In practice, the health of the coffee tree is the foundation of everything we drink, and protecting it from pests is a vital part of the industry's commitment to quality.
