Cool, I like bugs. Have a picture ?

If folks can see what kind of bugs you have, they will be able to be more helpful. Some are just a natural part of the process, and some happen when somethings off in the compost mix and can tell you how to improve things to optimize the process resulting in better, faster compost.

There are numerous insects that do help digest organic matter, Pill and Sow Bugs, Millipedes, Earwigs, Ants,and more, but they all need a cool, moist environment to live in. Their presence in a compost pile, therefore, indicates the material is too cool and too moist, although it will still convert from waste material to compost over time. Their presence in a compost pile also may indicate that other, less desireable, critters (skunks, raccoons, etc,) may visit and take off with what you want to go into your garden.

Although some find no problem with these wee buggers in a compost pile they are an indication that the composting process is quite slow.

Are there any drain/air holes in the barrel? If not you'll need to drill some pronto to let excess moisture out and air in.

If it smells bad, add more dry browns.
