Little worms in water butt!
My cat loves water from the water butt in the garden which I've only had in place for about a month, and I was horrified this morning to see that there are tiny little red worms in the water, only a few millimetres long.
I have read that it could be midge or mosquito larvae. I was wondering if anyone else has had this problem and can advise how to stop this happening again, I'm thinking maybe some fine mesh over the hole into the butt?
It is just one slimline butt with one connector coming in from a drainpipe.
Thanks in advance.
