Use the solar powered Water Wiggler to attract birds, keep mosquitoes from breeding in your birdbath and prevent algae from growing! Just place it in your birdbath and the solar panels will soak up the sun and power your Water Wiggler continuously. For best results, the Solar Water Wiggler should be used in full sunlight. The Water Wiggler features a unique agitator action that creates continuous ripples to prevent mosquitoes from laying eggs by eliminating stagnant water in bird baths. The Water Wiggler is easy to install…just place it in your bird bath and let it work! There is no wiring and no plumbing, and it’s completely silent.
