Wood worm in joists

[Lazurus]

Just moved into our new place and I cleaned out the single garage that the old boy before us had used as a small workshop. I noticed some active woodworn in the rafters (flat pent roof) so I gave it a good dose of Cuprinol wood worm killer 5 days ago. I noticed today there is still some active critters in the wood. Do I need to reapply or will the original spray act on and kill those still munching?

I doubt it is as dry in there as you expect for boring insects still to be active
