I have recently bought a chinese elm bonsai and i have noticed some pests in the pot and climbing up the tree. They are like a white see-through worm, but today i found a fly on there. Please can smeone advise me as to what to do. I have found a number of these pests, do you think it is a good idea to repot?
Thankyou for your help,
P.s., this is a pic of my tree!
