Don't leave Ethanol gas in equipment that is going to sit around for many months. To winterize everything I get a 5 gallon can of VP non ethanol and mix 2 stroke in it . All my saws and blowers etc make it through the winter without any problems starting.. Dump Ethanol gas out of two strokes...
They dont like that stuff. Use Just one bite brand and put it in one of those large black boxes so no pets eat it. Just one Bite will kill them i use it.
