  I have my pepper plants growing indoors in homemade compost,  nothing has crawled out.

  
  

  
  

  Did you sieve the compost first?

  Home made compost needs sterilising, for cuttings and seeds especially.  Heat briefly to over 60ºC.  
  
  I saw a USA reference to Hydrogen Peroxide - that might be worth investigating.

  I've never done this before - have you tried it? I researched it a bit and the neatest option seemed to be to use small quantities of compost in plastic bags, though they might melt in the heat? 
  I'd rather keep away from chemicals though.
