Yesterday we highlighted the fact that mosquitoes can transmit nasty diseases, and general steps to eliminate standing water where their larvae grow. As rain water harvesters, let's get specific: Don't let mozzies* get to your water! Our rain barrel design was inspected by an entomologist who said it is good for keeping out mosquitoes---as long as you keep the screened lid on and the overflow connected to its hose or pipe.
If you have a rain barrel or rain tank from Rain Barrels Iowa, it has an overflow: a brass hose adapter, a hose barb for corrugated hose, or a 3-inch or 4-inch diameter PVC, all of which to let extra water out in a controlled fashion when the container is full. And all of which can let mosquitoes in. From the mosquito's view, still water without predators is an ideal place to lay a few hundred eggs at once! So, if you haven't properly completed your rain harvest set up with a hose or pipe on the overflow opening, PLEASE DO THIS TODAY.
