Suspend contains the ingredient Deltamethrin - 4.5%
Don't think that because Demand has a higher ratio its stronger. It comes in a smaller bottle and you mix only a few ML per gallon of water. Basically it takes about half as much Demand to make the same strength Suspend.
Both products are about equal in effectiveness in my opinion. Both are synthetic pyrethroids chemicals.
