Springtails isnt due to overwatering mate
They will have been in the compost to start
Its just wet mediums are a good habitat for them

Letting your compost dry properly in between watering should sort it
It wont mate...trust me,once in they are virtually impossible to get rid of
Keep them under control and they shouldnt do too much damage
There are a few root drenches available but ive never used them myself
