Every winter during warm spells, there are temporary aphid population

With night time temperatures often near or below freezing, I can't very
well use a water hose to wash them off, and would prefer not to use any
kind of insecticides.
Are you worried about water freezing on the ground or on the plants.

If I remember correctly, farmers (strawberry, citrus) will spray plants with water to protect them from freezing. The water gives off the latent heat of crystalization when transitioning to the crystaline form and actually warms the plant.
