Kitten toilet problem?

ive 2 14 week old kittens and 1 of them keeps weeing in my hall and on my bed. Iv taken up the carpet and scrubed the floor and carpet before putting it back down(i rent the house) which didnt deter him. And iv used vinegar,aftershave,bio detergent + vodka but nothing works on the bed eitha. Ive used xanto stain and odor remover thats supposed to stop them but didnt also. They both use the litter but pegasus still wees on the floor and bed can anyone help me to stop it or explain why its happening?
