Just read an interesting article on B&G Sprayers (see attribution below). B&G equipment experts report that the brass spray tip on the B&G 1 gallon sprayer experiences 10% nozzle wear each year. This means after 1 year, your B&G sprayer is putting out 10% MORE CHEMICAL than it did the year before.
What does this mean to the typical PCO? It means that each year you use a B&G, your pest control chemical costs will go up 10%! The nozzle wears out at 10% per year, so the situation gets worse over time. Unless you can train your technician to walk 10% faster while they are using the B&G to apply chemical, you’re profitability will decline. B&G suggests replacing the tip every 2 years. Some other tips: clean your tip with a soft bristle brush. It is ok to use a toothpick if needed but do not use metal such as knife or pin, which will damage the tip and spray pattern. Clean your B&G perioidcally with a mild detergent. Inspect and replace gaskets and o-rings as needed.
I would appreciate your comments on this post.
