Birdbaths / Heated Baths     Mosquito-free Enzyme    Worried about mosquitos laying eggs in your ponds or baths?  This spray will take away the insects ability to land and lay eggs in the water!  To simplify the science, it breaks down the surface tension of the water so they can't successfully stay afloat, causing mature and even larvae mosquitos to drown. Simply spray the surface of your bath or pond anytime you refill it or on a weekly basis.  CareFree Enzymes takes great pride in using natural enzymes to solve tricky natural problems.  This solution is safe for your yard, birds and widlife when used according to instructions.  One four-ounce bottle will treat your bath hundreds of times.  (500 gallons) Price: $9.99 Qty: Add to my Basket
