I live inside the forest area, hence seeing many creatures at home are possible, ranging from bugs, snakes, crabs, insects, monitor lizards, chameleon, gecko, scorpions, etc. So yes it is prone to many things.
Carpenter Ants infest our home once in three-four months, and that is one of the nice things to happen according to me. Whenever that happens, our home becomes pest free for very long time, because ants take away all the pests from home, either dead or partial dead with them. And that includes their army carrying away cockroaches, geckos, etc. with them. And our home becomes pest free for long time!
And good thing is that those carpenter ants don't trouble our edible items, nor they get into our clothes, book shelves and neither they attack us. So we are thankful for their presence, and hence we usually give some foods to them as a gesture. We don't kill ants at any cost. Although Fire Ants are annoying for sure.
Will rat traps work on mice?
It had worked whenever we used, but my father also use some sort of solid cookie-like chemical substance to lure the rats. I don't know it's name or chemical name hence can't help you over it.
