I suffer from the atopic triad "Asthma, Hayfever and Eczema" - that spray irritates my breathing and eyes and nose.

I didn't realise it contained pesticides I thought it was just some kind of antibacterial spray (which I think aren't necessarily useful either).

This is more alarming and would explain my reaction. Sadly there is no way to be sure to avoid it despite your suggestions.

I suspect this will only gain attention as a problem when someone dies from anaphylactic shock or massive asthma attack (and even then only if they ascertain it was due to the pesticide which might be hard to prove).
