It's just assault
If these things are legal I think it should be perfectly legal for the babies, children and teenagers affected to assault the owners of the mosquito devices. These things really are nothing more than indiscriminate assault so if you own and fit one, then expect to be assaulted back, preferably with a needle to your ear drums and a foot in the face, or perhaps a visit to Guantanamo for some more of their strange and unusual torture.
