Flying Termites Season in Nairobi: What You Need to Know

In Nairobi, the rainy seasons bring more than just wet weather. They signal the arrival of flying termites, known locally as “kumbekumbe” or “chiswa.” These winged insects, also called alates, emerge in large numbers, creating a spectacle that is both fascinating and challenging for residents. Understanding the flying termite season, its timing, and how to manage it can help Nairobians prepare for this annual phenomenon. This article explores the essentials of the flying termite season in Nairobi, including why it happens, its impacts, and practical tips for dealing with these insects.

When and Why Flying Termites Appear

Flying termites in Nairobi typically emerge during the rainy seasons, which occur from April to May and October to November. These periods, known as the long and short rains, create ideal conditions for termites to swarm. The alates are the reproductive members of termite colonies, tasked with leaving their nests to mate and establish new colonies. After heavy rainfall, the warm, humid environment triggers their nuptial flight, where they take to the air in search of a partner.

The swarming usually happens at dusk or night, especially after a rain shower, as termites are attracted to light sources. Residents often notice them near windows, doors, or streetlights, where they gather in large numbers. The flight is short-lived, lasting about 20 minutes, after which the termites shed their wings and attempt to form new colonies. This natural behavior is essential for termite reproduction but can be a nuisance for homeowners.

Cultural and Nutritional Significance

In many parts of Kenya, particularly in western regions, flying termites are more than just pests—they are a valued food source. Communities like the Luhya and Luo consider them a delicacy, known for their high protein content and nutty flavor when fried or roasted. In rural areas, people set up traps using banana leaves or nets near termite mounds to collect them during the rainy season. Some even drum on the ground to mimic rain, encouraging termites to emerge. In Nairobi, while less common, fried termites can be found at places like Amaica Restaurant, served as a crunchy appetizer.

The nutritional value of termites is significant. They are rich in protein, fatty acids, iron, and zinc, making them a sustainable food source. In urban areas like Nairobi, however, eating termites is less popular, often seen as a rural tradition. Still, their cultural importance highlights a unique aspect of the flying termite season, turning a pest into a resource for some.

Challenges for Nairobi Residents

While termites hold cultural value, their swarming can cause problems in Nairobi’s densely populated areas. The insects are drawn to artificial lights, leading them to invade homes, offices, and public spaces. The sight of thousands of termites can be overwhelming, and their discarded wings create a mess on floors and surfaces. For some, the sudden influx feels like an invasion, causing frustration and discomfort.

More concerning is the potential for termites to cause structural damage. Subterranean and drywood termites, common in Kenya, can infest homes, chewing through wood, flooring, and furniture. Subterranean termites build mud tubes to access food sources, while drywood termites live inside wood, making their damage harder to detect until it’s severe. In Nairobi, where buildings are closely packed, termite infestations can spread quickly, leading to costly repairs.

Managing Flying Termites

To manage flying termites, prevention and control are key. Here are practical steps Nairobi residents can take:

1. Reduce Light Attraction: Turn off unnecessary lights at night during the rainy season, as termites are drawn to light. Use curtains or blinds to block indoor lights from attracting them.
2. Seal Entry Points: Check windows, doors, and vents for gaps where termites can enter. Install screens or seal cracks to keep them out.
3. Clear Debris: Remove wood piles, mulch, or other cellulose materials near your home, as these attract termites. Keep your compound clean to reduce nesting sites.
4. Professional Inspections: Schedule annual termite inspections with pest control services like Rentokil or Rafiki Pest Control. They can identify early signs of infestation, such as mud tubes or hollow-sounding wood, and apply treatments like liquid barriers or baits.
5. Collect Safely: If you choose to harvest termites for food, use safe methods like placing a lamp over a bowl of water to trap them or setting up banana leaf traps near mounds. Ensure they are collected from clean environments to avoid contamination.

Looking Ahead

The flying termite season in Nairobi is a natural event with both cultural significance and practical challenges. While some embrace termites as a nutritious delicacy, others see them as a pest that requires careful management. By understanding their behavior and taking preventive measures, residents can minimize disruptions and protect their homes. As Nairobi continues to grow, balancing urban life with natural phenomena like the termite season will remain an important part of living in this vibrant city.
