There is a scratching noise coming from the plastic in my conservatory. I have had a look outside and there is a covering on the front of the upvc that has come out and an entrance probably an inch and a half all the way around exposed. I initially thought mouse that's in there as there's very loud scratching but its daytime and doesn't let up overly if I bang it. Then I thought potentially wasps? Or bees? I have no idea? I don't want to leave it so that if it is a mouse it can come in but that leads me to my next question, how on earth am i going to get rid of whatever it is? Please help???
