Does anyone know the effect of river moths on citrus?

I live RIGHT on a river (great for the humidity) but horrendous on the river moths. I seriously have to sweep them from in front of me to see at times when I try to go to to the basement (outdoor entrance) I have a bug zapper, an extra large one. It collects so many each night that at times I have to clean it out every morning.

I would hate that they'd nest or eat my trees. It is definatly my main concern for having my trees outside
