I have had good results with Demand CS for controlling mosquitoes, wasps, dirt doppers and, to a lesser degree, spiders in our outdoor living areas and around the overhangs of our house. It appears from the produce descriptions that the Onslaught FastCap Spider and Scopion product may provide a more targeted control for spiders. Might I see more effective control of spiders around the exterior of the house if I were to use BOTH products (Demand CS and Onslaught) at the same time?
These products should not be mixed together. There is no valid reason to mix Demand CS and Onslaught FastCap Spider and Scorpion together. Demand CS is a synthetic pyrethroid and Onslaught FastCap already contains a synthetic pyrethroid, so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.
