Sounds like an anthill. The way to get rid of an anthill is to saturate it with gas, light it on fire, step back and watch the little b@st@rds burn.

Actually the finest way to get rid of an anthill ever devised is the use of mass quantities of 20 Mule Team Borax, or Borateam. The little bastards find it delicious, and deadly. After a few weeks, the ant hill will sink from lack of maintenance.
