Hi Joanne, if it's really jumping it's very unlikely to be a toad. Toads are usually very sedate and walk rather than jump. If you have got a toad, let it get safely out of the way--it will do a good job in your garden. I have a few living in my backyard. I put the water butt on bricks to make a safe haven and stuffed moss into it.
Toads are remarkable--we had a young toad that was a beautiful burnished bronze colour with coppery eyes, and they can live to a great age.
I know they say toads will eat slugs, but in my experience of keeping them I find they would rather eat almost anything else. Watching a toad drag its foot across its mouth to wipe off the slug slime tells you everything about how much they aren't keen on slug treats. If you want to see a toad become almost animated, offer it a cricket :). Must be like heaven!
Frogs are a different story and not half as nice characters.
