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? ...
This stuff will kill all the bugs and wile its expensive at first, It will last you a few years, It only takes a little bit in a gallon of water, and it just keeps killing. I use it in the storm shelter, it even kills scorpions and fire ants, and it lasts a long time.
