A new swarm on foundation is a good time to treat for varroa. But I have always recommended that the treatment shoud be done after about 4 - 6 days, when the queen has started to lay eggs. The mites are still on bees. They go to brood about 1 - 2 days before capping.
Some swarms don't enjoy to be treated the first day in a new home, and decide to try find an apartment with better odour.
