Spiders are everywhere under eaves and on porch. I need a spray for spiders that does not leave a residue. I am looking at 'Demon WP', 'Demon Max', 'Suspend SC'. , 'Suspend Polyzone'. Which is the best spider spray with the longest residual that dries clear?
Suspend Polyzone has the longest outside residual and is great for spiders. It dries clear and is applied every three months.
