Mosquitoes have a nasty way of turning a backyard water fountain into something less enjoyable. Of course, it should be noted that mosquitoes only really reproduce in standing bodies of water. In our 2nd Backyard Water Fountain Install article, we showcased the installation of a small water fountain in the one of the PSL Team member's backyard. This was meant to replicate the original article How to Build a Backyard Fountain for Your Garden or Patio for Under 65 Dollars. Unfortunately, we waited to long to add a timer mechanism, and without running the fountain 24/7 resulted in a quick rise of mosquito larvae. As we do not particularly care to have mosquitoes breeding in our fountain, we decided to take a step to reduce the population. We found Summit Mosquito Dunks on Amazon, received them within 2 days (thanks to Prime Shipping), and put them to use immediately after receiving in the mail. It's been a few days now, and our mosquito larvae problem is completely eradicated.
