A portable, self-sustaining, automatic device for eliminating mosquito larvae operates throughout the entire mosquito breeding season. Mosquitos are lured to lay eggs in the stagnant water contained within a breeding bowl of the device. The subsequent larvae is disposed of by tipping the bowl or uncovering a bottom bowl opening to empty the bowl of water and larvae and kill the larvae in a timed cycle before they become mosquitoes. A water reservoir supplies sufficient water to replenish the bowl throughout the season. The device is solar powered and timed to correspond to mosquito breeding cycles.
