Ortho products have been reliable over the years. This spray is no exception. I like the foam as it covers the area, in this case, a ground wasp nest. Then they have to crawl through it to get out or get back in. A word of caution, give a test spray before you need to use it. My initial spray was more like 4 feet than 20 feet. However after the first spray it did reach a distance, more like 15 feet horizontally than 20 though. Still that keeps you well away from the nest and if they get the foam on them, they don't fly more than a foot before crashing.
Kills wasps; yellow jackets; mud daubers and hornets
Entrapping foam stops wasps instantly and kills insects that return to the nest
Jet spray reaches nests up to 20 feet above ground
If reviewing a product, it may have been received free of charge. That will NEVER have a bearing on my recommendations.
