We do not usually recommend Suspend for bedbug treatments because of the risk of resistance. Please take a look at our bedbug kits to see the products we recommend for bedbug treatments: http://www.domyownpestcontrol.com/bed-bug-kits-c-39_97.html
You will notice that there are several product formulations in each kit and this is to guard against resistance issues.
Suspend SC can be used as a broadcast spray on lawns and on ornamental plants to protect these areas from lawn/ornamental plant infesting insects and it can be used as a perimeter barrier spray to stop pests from getting into your home. Each of these applications and application rates are very different. Can you tell us specifically what type of application you are trying to complete so we can better advise you?

Suspend SC will not harm your plants. Your cats should be out of the area prior to the applications and they can return to the area after it has dried. We have linked the Suspend SC product label below so you can read how to use it for bedbugs:

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.
