Yes, woodworm can come back after treatment if the underlying conditions that led to the initial infestation are not addressed or if the treatment was not effective in eradicating all the wood-boring beetles and their larvae.

Woodworm treatments typically involve applying insecticides to the affected wood, which can kill the larvae and prevent the beetles from laying new eggs. However, if there are any areas of the wood that are missed during treatment or if the insecticide does not penetrate deeply enough into the timber, the larvae may survive, and the infestation can continue.
