Lampe Berger has a simple ritual which combines the unique Lampe Berger diffusion method with an effective insecticidal formula for long-lasting elimination of mosquitoes. Perfumed with Ocean Breeze fragrance. The formula repels mosquitoes, bugs, ants and flies. Just light it for 2 minutes, blow out the wick, and let it work for 30 minutes for 100% of insects repelled! Need it longer? Just reheat the stone. It's a classy way to clear the summer air of bugs rather than those messy citronella candles! $30 for a starter kit.
