Sticky Stuff!

I've tried many different ways of preventing maggots in apples and plums over the years. I don't like spraying so I thought I'd try a good old fashioned grease band.
Stickier and messier than black treacle, this band of grease goes all the way around the trunk of the fruit tree at this time of year because the little fruit moths climb up the trunk from October onwards and through the Winter, making a home for themselves and their eggs in your fruit buds. Next Spring they hatch and make their way into the flowers and the developing fruit.
So the idea is that they are prevented from crawling up the tree in the first place (they cannot fly!). I have yet to decide what to do when a certain yellow Labrador comes into the house covered in black grease? Any ideas?
