We have a hose end sprayer with 1 oz to 8 oz on the dial and it sprays 4 gallons of water per minute. The bottle is 32 oz, how many demon WP packets do we put in the jar to kill spiders?
You cannot use Demon WP in a hose end sprayer. This is a wettable powder that must be mixed and dissolved into water at the rate of 1-2 packets per gallon of water. There is no way to make a hose end sprayer suck up a powder to disperse in the water as these hose end applicators are only designed for liquids. You also cannot dilute it first and then pour it into the hose end bottle as you will not be accurately treating with the right dilution. You will need to use a hand pump sprayer similar to this Chapin Premier Sprayer to apply this type of product for spider control.
