Can an exterminator's pesticide spray cause nose bleeds for a 4 month old baby?
If not, what else could cause repeated but non-serious nose bleeds?

Recently our apartment complex had our apartment sprayed by an
exterminator because of a spider outbreak.  Ever since then, our baby
has been having some repeated but minor nose bleeds.  It's not like a
severe nose bleed or anything serious.  Just a little bit of blood
comes out with some snot.  I personally think it's just her sensitive
nostrols and maybe some dry boogers that are causing it but my wife
wants some reassurance.

Can someone help me find out if the pesticides could cause this or if
it is something else?

Thanks!
