If Demand CS is leaving a visible residue, then we would recommend to use a lower dilution rate (0.2-0.4 oz. per gallon of water). Also, be sure you are only spraying as a spot and/or crack and crevice treatment. You could also consider going to an insecticide that is not micro-encapsulated, such as Talstar P. If you are removing all the reside, then you would need to reapply the insecticide.
When used as directed on the product label, Demand CS is safe to use outdoors in areas where birds frequent. Be sure the birds are out of the area when the Demand is being applied and try to keep the birds away until the area is dry.
Demand CS can be applied indoors to cracks and crevices and other locations listed on the product label.
Demand CS can be wiped up with hot water and soap. The product is safe for your dog even if over sprayed on the floor after it has completely dried.
Demand CS is not a systemic. As in, it will not leach into soil. It does not leach into soil like Imidicloprid products.
Demand CS should kill Yellow Jackets after they come in contact with it, however it is not specifically labeled for them. This would not be our number one recommendation for Yellow Jackets because it can take some time to kill them. Please check out our article "How to Get Rid of Yellow Jackets". If you can get to the openings where the yellow jackets are coming in and out from, we highly recommend applying a dust like Tempo 1% Dust and when the yellow jacket comes in contact with it, the dust will transfer from yellow jacket to yellow jacket and kill off the entire nest.
Demand CS should be applied when there is no rain the forecast for 24 hours after application. The outdoor residual of the product is up to 30 days. Heavy or prolonged rains can diminish that residual slightly.
We would recommend that you keep animals out of the area while Demand CS is wet. Once the product is dry, it is safe for pets/animals to return back to the area. There is such a small amount of the active ingredient that actually gets on the bugs before they die that it will not affect any animals that consume the dead bugs.
