If you’ve ever had a picnic ruined by wasps or found them nesting around your property, you’ll know how much of a nuisance they can be — not to mention the risk they pose to native wildlife. That’s where Vespex®, a revolutionary wasp bait developed right here in New Zealand, comes in.
🔬 What is Vespex®?
Vespex® is a specially formulated protein-based bait designed to target and eliminate Vespula wasp species, including the common and German wasp. These wasps aren’t just annoying — they’re invasive pests that threaten our native ecosystems and biodiversity.
Developed by Merchento in collaboration with the Department of Conservation (DOC), Vespex® uses a low-dose insecticide called fipronil. Wasps are drawn to the bait, collect it, and take it back to the nest — where it does its job quietly, eliminating the entire colony including the queen.
🌱 Safe for Bees, Pets, and People
One of the standout features of Vespex® is how selective it is. Unlike sugary baits that attract everything from bees to birds, Vespex® is protein-based — meaning it’s highly attractive to wasps, but not to bees, reducing harm to these crucial pollinators.
It’s also considered low-risk to pets, native birds, and humans when used correctly. That makes it a top choice for both conservation areas and urban pest control.
🔧 How Does It Work?
Here’s a quick breakdown of the process:
- Wasps are monitored during the peak protein-foraging season (late summer/early autumn).
- Bait stations (such as Wasptek™) are placed in high-activity areas.
- Wasps carry the bait back to their nest.
- Fipronil spreads through the colony, leading to full nest elimination within days.
In field trials and DOC operations, Vespex® has reduced wasp numbers by over 95%, making a massive difference in native bush areas and public spaces.
