scorpions are in the backyard away from house, But I want them completely gone. I find one a night with blacklight. Should I stick with suspend? The deltamethrin granules? Other product? I live in dry az climate.
You can actually stick with the Suspend and broadcast spray it over the lawn. Your property is apparently favorable to scorpions so it is unrealistic to believe you will be able to get rid of 100% of the scorpions with insecticides alone. You should also follow the scorpion control methods listed below to make your property less favorable to this pest.
Non-insecticide methods for scorpion control are:
Harborage Removal- Harborage removal is key to scorpion control and will greatly reduce the numbers of scorpions in the area surrounding the structure, making it far less likely that they will enter. Harborage removal includes eliminating piles of lumber, bricks, and other stacked items that create clusters of tight spaces, elimination of vegetation and other heavy ground coverings near homes and buildings, trimming back tree and shrub limbs from walls and roof, and keeping gutters clear of leaves and other debris.Exclusion- Scorpions and other pests can be kept out of structures to a large degree by installing tight-fitting screens, weatherstripping around doors and windows, and caulking cracks and crevices.
