Wonder what triggered em though, they should be hidden until that hole is opened up.

Come on this is less than the poison ship randy dropped into my tribes farming area after to months ingame time.
( just after I replanted the plants that got killed by a blight )
You can do it.

A three tile trap corridor for the reaper should do it, and you can kite the centipede easily.
Oops I oversaw the second centipede .. so .. maybe a longer trap corridor

Worst case scenario would be if .. no I won't jinx you.
