I'm no expert, but I've been to a several sites (Tikal, Xunantunich, Cahal Pech, Lamanai, Santa Rita) and there was no need for bug spray and you most certainly don't want to be wearing long pants and shirts.
Shorts, t-shirts and a good pair of sandals is the way to go when touring these sites. However I've read in this forum that there are certain sites (such as Cerros) where the bugs are very active, although I've not experienced it myself.
