If you want an easy way to help your local pollinators, then consider building a water station! Many plants and crops rely on pollinators, so the more you attract and help, the healthier your garden will be (for example: "โBee pollination improves crop quality, shelf life and commercial value.โ)
For a basic one, you will need:
Tray or dish
Rocks
Water
The tray or dish is to hold everything, and the rocks are to give the pollinators something safe to land on. Without the rocks, you will likely end up with drowned bees. Due to evaporation, you may have to fill the dish once or more a day.
HOWEVER, although that is the most common method, there is another one that I prefer that was taught to me by local beekeepers. They use a refilling dog bowl instead of a dish, so it doesn't have to be filled as often.
Seems like the perfect situation for a BTI dunk. It contains a bacteria that will kill mosquito larvae only, and is certified for organic gardening by the EPA.
