Ant control in my hugel style raised bed

I was going to chop and drop my snow peas today, add some compost and plant strawberries. I noticed a ton of little black ants, going into a hole in the raised bed. The raised bed is pretty new.  The bottom is full rotty wood, then soil, branches, soil, wood chips, compost, soil, composted wood chips and chicken manure. The top 18" is organic compost, and organic soil.  Early spring I planted snow peas.  I might see an ant in the garden now and then, mostly if I have aphids. But this is different. No aphids, and tons of ants.  I usually don't do anything about bugs, except aphids which I just spray off with water.  I just decided to get rid of the ants. I put diatomaceous earth in the hole, and dusted the top of the bed. I need to get the strawberries planted, so how long should I wait?  I'm going to top the bed off with organic compost. When I plant the strawberries I will have to water, then the DE is useless.
Maybe I should have left the ants alone. I don't know. What do you think?

I would leave the ants alone, they are just doing what they do well.

As long as they're not fire ants, I would leave them alone, too. I'm hoping by adding more wood and hugelbeds to my garden, the nicer ants that inhabit the nearby forest will displace the fire ants in my garden. They seem to be beneficial in the forest.

Ok thanks. I will add compost, and plant my strawberries today.

Now I'm worried they could be carpenter ants. I always thought carpenter ants were large, but I'm reading there's only a slight difference. The reason it matters is the raised bed is made of coordinated steel, and recycled redwood fence boards.  There's a lot of wood in this raised bed, I probably brought the ants myself. The bed was made with recycled materials, so I know it won't last a very long time, but I would like to get as long as I can.  Gardening, it's always something.

Maybe the raised bed is too dry?
