The threat of mosquito infestation is a real concern for homeowners who use rain barrels as a means of water conservation. Mosquitoes like to like lay eggs around standing and stagnant water. Most 55 gallon rain barrels are manufactured with screened lids that deny mosquitoes access to the stored water. However, having a mosquito-proof lid on your rain barrel is not the only precaution you should take. Below is a list of additional measures that will protect you against West Nile and other diseases that mosquitoes transmit.
By taking these precautions, your properly protected rain barrels can actually help prevent unwanted mosquito breeding by eliminating the standing water which results from a heavy rainfall. Ready-to-use rain barrels can be purchased at many lawn-and-garden centers. For the do-it-yourselfer, kits used to retrofit recycled water barrels are also available.
