Please, I wonder if anybody can help. I'm asking this on behalf of my parents. They have recently started a compost heap, you know local council incentive to recycle etc. I'd say they've had it 2-3 months. They've only put fruit/veg scraps, tea bags and egg shells on it, nothing from the garden as yet.

Mum said she went to it the other day, lifted the lid and closed it VERY QUICKLY as there was, what she thought looked like loads of mosquitos in it. She's not 100% sure, could have been tiny flies or similar.

Sorry to be so vague, it's making me itch just typing about it. Mum has been badly bitten by something over the past week and now she's beginning to connect the compost with the mossie???? Sorry if I sound dim, but any advice would be most welcome, and i'll pass it on to my parents.

Thanks so much in advance!
