A 2.5 to 3 gallon backpack sprayer weighs roughly a third less full than a 4-gallon one, which matters on a long route of pest treatments or for a smaller person. Pest control sprayers such as the B&G models are built for spraying around foundations and eaves, with high pressure and a pin-to-cone tip. Per gallon of tank they cost more than the full-size sprayers, so pick one for the lighter load, not the price.
