You could try spraying them with a solution of soapy washing up liquid and see if that helps if they're stored indoors. I find they often seem to come outnof the compost. The other thing I've tried with indoor plants is giving them a light spray with anti bacterial liquid. - the type you use foe cleaning your kitchen worktops. Sometimes helps to keep these infestations under control if you don't want to go out and buy a special garden product and you have some to hand. .
