Your mosquitos must be something else! We have them here, sometimes bad enough that my horses look gray because there are so many. But between these and the ones on Guam, never had problems like you are describing!
The first shot may have put them into anaphylactic shock, and the second may have been something like epinephrine to reverse it.
Another tidbit that you might be interested in... sometimes when my birds get runny poop, I grind up some hot peppers and add it to their water. I use Thai Dragon hot peppers, it seems to clear up the poop problems. I don't think the birds notice the heat, there are actually reports of the wild turkeys in Mexico eating hot peppers growing there.
