While its possible the Suspend or other similar active ingredient products could potentially control bermudagrass mites, the only product specifically listed for their control that we are aware of is the Triple Crown Insecticide.
Our most popular product for Arizona residents is definitely our Demon WP. Suspend SC and many other products are also good, but not as strong as Demon. Since Demon WP is a powder that is mixed with water, it is easier for scorpions to pick up on their body and faster acting. Demon WP packs a punch which is what you need for the Arizona scorpions, spiders, and other insects. It is very effective, yet very safe around children and pets at the same time. It is a general use product that is labeled for all insects and is a great all around use product. You should re-apply the product every 30 to 60 days for best results.

We are sorry to hear that you are having trouble measuring Suspend SC into the measuring side. The product can be measured by squeezing the bottle and allowing it to go up the straw on the side of the bottle to fill the measuring side. Once measured to the amount you want (1.5-2oz) you fill it into your gallon sprayer and spray. Please make sure to agitate the mixture first before applying.

Yes, Suspend SC may be used in hose-end sprayers. Be sure to check the instructions for the hose-end sprayer that you are using as some hose-end sprayers require water to be added to the resevoir with the insecticide, while other hose-end sprayers do not. Make sure to shake the Suspend SC well prior to use.
Suspend SC is labeled for interior crack and crevice application and listed outdoor use for listed pests only. We recommend that you contact your local cooperative extension office for a proper pest id for the mite species that you are experiencing.
