So, in Canada we didn't really have to worry about exterminating bugs in our home. There were screens in all the windows and the patio door so mosquitos didn't take over and that was about it.
It's different here; we're not quite prepared for the fight. We've fought cockroaches, silverfish, red ants, black ants, flying ants, houseflies, spiders, bedbugs, mites, fleas, and these crazy-miniscule-hard-shelled-pre-historic-armadillo bugs that are impossible to kill. Things get really bad when it's rainy; it's been rainy for 10 days straight. Everyone is looking for a dry place to park their hungry selves.
I don't mind the spiders so much. They've encamped in every corner of our home, catching and feeding on many of the other visitors. I suspect they might be biting us at night too, but I'd rather blame the legendary bedbugs and less savory beasties.
The dirty webs that hang on our rafters, in our door frames and in the corners may be ugly, but I welcome them if it eases our battle with other foes. The enemy of my enemy is my friend.
