I have a courtyard that has a koi pond and it is crawling with spiders. They are in the corners, in the windows, etc., etc. i need a residual spray that I can use. It would be great if the spray didn't leave a residue on the walls or sliding glass doors.
Cyzmic CS Micro-encapsulated Insecticide should not be applied within 25 ft of any body of water or koi ponds. It is highly toxic to fish including koi.
