though the size of this is stated in the product description nonetheless i was surprised how much we received for the money. comes with an attached spray nozzle so no need for an additional sprayer. safe on paint which was one thing we wanted to make sure was the case. we used it around our house perimeter, round all the window frames to keep primarily spiders out. we don't have issues with other critters just spiders so this is a great product for a very good price. fyi to supplement we did also get some sticky pads ALAZCO 6 Glue Traps - Excellent Quality Glue Boards Mouse Trap Bugs Insects Spiders Cockroaches Mice Trapper & Monitor NON-TOXIC to add another layer of protection. those we just lay flat on the inside of our window boxes. they work well catching anything that might make its way past the ortho barrier. fyi last year doing the same routine only three dead spiders made it past to the sticky pads.
