Hot sunny weather makes our compost bins work faster but they can get too dry.
Here's what to do to keep them moist:
Add extra wet material like grass mowings and kitchen waste.
If rain is forecast, leave the lid off a covered bin.
Pour a bucket of water round the sides where conditions are driest.

You may find ants in your compost bin.
Ants will do no harm – they help break down the material. But your bin must be quite dry. You should add in sappy stuff like annual weeds or fresh grass clippings. During a hot spell, you might even need to water your heap! Circular bins sitting directly on the soil are the best design as the condensation quickly runs down the sides keeping the material moist. Square or hexagonal bins that have “fins” to keep the composting material away from the sides are more likely to dry out round the edges and will probably need an occasional bucket of water to keep the ingredients moist. The attractive ‘beehive type’ bin lets in far too much air, so can be a problem here.

Hot weather may attract lots of flies to your compost bin
They’re attracted to the rotting fruit peelings in the bin. Mask the smell by covering with a layer of fresh grass clippings or top soil.

If you need to empty your compost bin during hot weather
Do so quickly and do not leave either finished or half rotted compost spread out in the sun. It will quickly dry out and those essential micro organisms will die.
