Suspend SC is effective in direct sunlight, but if you do plan to treat in areas with direct sunlight, we would recommend Suspend Polyzone instead, as it has a special polymer coating which enables it to last longer under those direct UV rays. Suspend Polyzone will last up to 90 days outdoors, whereas Suspend SC will only last for about 30.
