I am thinking ahead a bit. We have lots of various water sources around us. Most of it moving, but we also have several vernal ponds. Soon there will be lots of mosquitoes ready to nibble on us. I am planning a three way attach this spring and summer.
1. The last couple years we have sprayed around the edge of our yard a very concentrated garlic solution. You can find it here. We spray it at the same time we mow the lawn. This keeps the strong smell of garlic diluted a bit with fresh cut grass smell. We have found the garlic solution to work well. It does get washed away by rain.
2. We just built bat houses. You can find kits here. We are hoping bats will move in and devour the mosquitoes.
3. I am planning on making a homemade mosquito trap. I found instructions here.
I will let you know how it goes.
