We had the same problem at our old house. They love damp and organic. Guess the
damp may explain your explosion this year.

We tried some DIY fixes wih various "stuff" but then I began to wonder what
toxic compound might result from this stuff and that stuff mixing together.

When it got to the point I couldn't stand it anymore (they crunch when you step
on them) and we were shoveling them up by the 5-gallon bucket, I called in a
professional pest control operator to deal with it. (I knew there must have
been a reason the former owners left the name and number taped inside a kitchen
cabinet.)

When we moved to this house (five years after the attack), I found dead
centipedes in boxes of packed dishes in the attic (three stories up!)

Best of luck in getting rid of them.
