Mosquitoes will fly from other bodies of water, even as small as a gallon or two, so any sort of garbage like a tire or a plastic bag that holds even a little water is enough for them to breed in.
Having your own pond will not tempt them away from other bodies of water.
You can sure protect your own pond from mosquitoes, though.
