Insecticide Recommendation for Perimeter Spray

As indicated in this thread,, I completed the perimeter spray with Demand-CS several days ago. 4.5 gals was used with my Flowzone Typhoon sprayer and I followed these instructions:



I also removed all spider webs from the property and knocked down all of the wasp nests before performing the spray. So far, I have not seen any yellow jacks return or any new wasp nests.

Also wanted to recognize @fisher83 for all of the help he provided me via PM.
 
Update:

Used Demand CS for two sprays (May and July). The May spray worked incredibly well - lots of dead bugs showed up within days. July spray resulted in fewer dead bugs, possibly because the bugs are already dead?

I ran out of Demand and switched to Fendona CS. Other than being more expensive and having a slight odor when used inside the garage, I am not seeing any differences.

Does anyone have experience with Tandem (also sold as Demand Duo)? It seems like a good product to use in rotation since it is a dual-action Group 3/4A.
