I have a birdbath and in the summer it accommodates many mosquitos' eggs. It's concrete, so I would rather not pour it out each time. I also don't want to poison the water as to not harm the birds. I hope to deter the occasional roaming Zikachu, thanks!

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Does not seem to need a life hack — A "life hack" is a seemingly intractable problem that can be solved by thinking outside the box. Unfortunately, everyday "How to…" questions about learning a craft or new skill are outside the scope of this site. See about Lifehacks. If the author can show how this needs an "outside the box" solution, edit and 'flag' to reopen." – Robert Cartaino
