I'm trying to create a wildlife garden at our new home. There is an established frog pond there already. This morning I just saw a rat around the pond - walking down to the water and scurrying amongst the marginals. The pond is LOADED with tadpoles at the moment. Do they eat the tadpoles?
Anyway, the wider question is - the rat will contaminate the water, right?
So what do I do about it, in the least harmful way?
I have seen mice around our garden, but it's a large space and I expect (and want) to share it with widlife, but a rat is a step too far!
