Cicada killer wasps dig underground burrows where they can leave food for their young. While not aggressive, their stings are meant to paralyze cicadas and are fairly painful. Where cicada killers cause the most damage is with their tunnels, which are extensive and displace several pounds of dirt. If located near tiled patios or gardens, they can cause structural damage and stunt plant growth. Proper pest control is a must to avoid problems early on.
