Controlling Coptotermes gestroi with Exterminex

The Asian subterranean termite, Coptotermes gestroi, has become one of the most damaging termite species across tropical regions. It’s aggressive, forms huge colonies, and causes significant damage before most homeowners even realise they have a problem.

In Asia and the Pacific – this species has established itself as a serious threat to both homes and commercial structures. For pest control operators on the ground, the challenge has always been finding a solution that doesn’t just slow termites down, but eliminates the colony.

Why C. gestroi is a problem

Unlike some other species, C. gestroi forages widely and can build massive underground networks. They attack timbers quickly, and traditional soil treatments often struggle to reach every tunnel or gallery. That’s why infestations can bounce back even after chemical treatments.

How Exterminex tackles the challenge

Exterminex was designed with species like C. gestroi in mind. Our system uses both in-ground and above-ground stations, placed directly in the termites’ foraging zones.

The key difference and the secret to success with Exterminex is the bait itself. Exterminex cellulose matrix is enhanced with patent and scientifically proven feeding cues, Being highly palatable to termites. Once they start feeding, the active ingredient is shared throughout the colony by trophallaxis, the termites’ natural food-sharing behaviour. Over time, this ensures the entire colony, including the queen, is eliminated.

Results we’re seeing

• The Pacific: Since C. gestroi was first reported there in 2009, demand for effective control has grown. Trials with Exterminex have shown strong bait acceptance and a steady decline in activity in treated sites.
• Asia: In markets such as Malaysia, Singapore and Thailand, pest control companies are now using Exterminex as part of their frontline approach to managing C. gestroi. Consistent bait uptake and colony collapse are being reported in both residential and commercial sites.

Best practice in the field

Operators using Exterminex for C. gestroi control have found the best results come when:

• Stations are placed where termite foraging is confirmed.
• Bait is replenished regularly to maintain feeding pressure.
• Sites are monitored closely until colony activity stops.
• Follow-up inspections are carried out to ensure termites haven’t re-established.

Looking ahead

The fight against C. gestroi is ongoing, but Exterminex is proving to be a reliable tool for pest managers across Asia and the Pacific. By combining smart station placement with a bait matrix termites prefer, we’re helping to protect homes, businesses and communities from one of the region’s most destructive pests.
