Just finished applying some flea killing spray on the back lawn

I've previously put down granules and saw some results but I don't think I applied enough water to fully activate them. Since then we've had some rain so that, along with the spray (same treatment, different delivery system) SHOULD make a difference. I still have some granules and will use them, depending on what results I see from today's application. In about 10 days, again, depending on results, I'll use the 2nd bottle of killer spray.

I triple checked myself before coming inside and saw zero fleas on my clothes. I am hoping to be able to enjoy some time in the shade of my maple tree, this afternoon.
