I am trying to figure out where spiders are coming into my TC. It looks like there are air intakes on the unit inside the TC. Are there no fresh air intakes on these air conditioning units? ...
I know not everyone cares for using chemicals, but years ago I discovered Black Flag Spider Killer spray and it seems to be a good deterrent to the little critters making themselves at home. Every couple of months I spray it in corners and around slides and other such entry points.
