Based on a 4.7-star rating across 2,774 verified reviews, the answer from customers is yes. Mosquito TNT 2.0 works by producing carbon dioxide through a yeast-based reaction — the same signal mosquitoes use to locate people. Positioned correctly (along the perimeter of your yard, in shade, between the direction mosquitoes approach from and where you sit), the trap intercepts mosquitoes before they reach you. Most customers report noticeable results within 24–72 hours of setup.

Yes — Mosquito TNT 2.0 is safe around kids and pets when used as directed. The formula uses five ingredients: yeast, D-glucose (sugar), sodium bicarbonate (baking soda), citric acid, and sodium lauryl sulfate. Follow label instructions and keep the trap positioned out of reach of very young children.

One refill cycle lasts up to 30 days. Refill packs are available separately, keeping the ongoing monthly cost low. For best results, hang the trap in a shaded spot — direct sunlight reduces the effectiveness of the CO2 reaction.

Customers use it successfully on patios, decks, in backyards, and in garden areas. Placement matters more than location: position the trap between the direction mosquitoes are coming from and where you sit. For yards near wooded areas or water, units distributed at different entry points along the perimeter work better than a single central placement.

Mosquito TNT 2.0 is a passive CO2 trap — it works continuously without requiring you to be present or to apply anything to your skin. It complements rather than replaces personal repellent spray or UV lamps. The Tougher Than Tom Mosquito Eliminator Spray protects your skin directly, and the Mosquito Eliminator Lamp adds a layer for evening and nighttime use. Many customers use all three as part of a layered system.

Mosquito TNT 2.0 is designed for outdoor use.
