Corect.
Insa vaporizarea se poate face oricand fara a dauna puietului, asta e avantajul. Dezavantajele sunt insa prea multe: in primul rand timpul de aplicare apoi riscul pentru cine aplica.

Does vaporization hurt the bees?
Radetzki didn’t note increased bee mortality after winter treatment. Heinz Kaemmerer of Heilyser Technology Ltd. says: “We treated several colonies for 3 months during winter, once a week with the vaporizer and all colonies survived.” “With brood, colonies can be treated with the right amount of OA 3 to 4 times, a week apart; there is no harm to bees, queen or brood.” Medhat Nasr confirms that vaporized oxalic is very gentle to the bees.
Conclusion
I’ve presented the facts about oxalic acid, and will let you draw your own conclusions. The dribble method, used once during the broodless period, has been demonstrated to be effective and safe, although it may somewhat suppress colony buildup in early spring. It is legal, and recommended, in most countries, and will “soon” be registered for use in the U.S. Heat vaporization, on the other hand, has some advantages for winter treatment in cold climates, but the question of operator safety lingers. It faces that significant hurdle in order to be approved by the EPA (I wouldn’t hold my breath)(pun intended).
