5 Reasons Your Bug Zapper Isn't Catching Mosquitoes (And What Actually Does)
Here's why millions of homeowners are ditching their bug zappers — and finally getting a backyard they can actually enjoy.

❌ 1. Bug Zappers Use UV Light — Mosquitoes Don't Care
UV light is great at attracting moths, beetles, and midges — insects that navigate by light. Mosquitoes are CO₂ hunters. They follow your breath, your body heat, and your skin's scent. UV is the wrong signal entirely, and no zapper wattage will change that. The University of Notre Dame proved it: mosquitoes made up just 4.1% of what bug zappers actually caught — across an entire season.
❌ 2. For Every 10,000 Bugs Your Zapper Kills — Only 8 Are Mosquitoes
In a controlled University of Florida study, researchers counted exactly what one standard bug zapper killed in a single night: ~10,000 insects. Eight were mosquitoes. A 10-week University of Delaware study confirmed it — 0.22% of 13,789 insects killed were biting flies. The rest were moths, beetles, and the beneficial insects your yard needs. Your zapper is working perfectly. Just not for mosquitoes.
❌ 3. Your Zapper May Be Making the Problem Worse
Bug zappers kill the parasitic wasps, beetles, and predatory insects that naturally control mosquitoes. Remove the predators — the prey population expands. Notre Dame researchers found yards with active bug zappers actually had more female mosquitoes (the biters) flying around than yards without them. The University of Florida estimates 71 billion non-target insects are zapped across the US every year. You're not solving the problem. You may be feeding it.
✅ 4. Mosquitoes Follow CO₂ — BioLure Generates Real CO₂
BiteShield combines UV light with BioLure — a proprietary powder that generates real CO₂ through two separate chemical reactions, mimicking the exact signals mosquitoes use to find a human host. Yeast fermentation produces a sustained CO₂ plume throughout the night. A citric acid + baking soda reaction fires an immediate burst at activation. This is the same CO₂-based mechanism used in professional mosquito surveillance programs worldwide. UV attracts moths. BioLure attracts mosquitoes. BiteShield has both.
