Cyzmic CS is labeled for bed bugs and will kill them. You can apply Cyzmic every 21 days indoors. It is very important to follow the product label instructions and resist the temptation to spray 'anything and everything'. According to the Cyzmic product label :
Bed bugs: Clean floors and surfaces by vacuuming. Apply as a coarse, low-pressure spray to harborage areas including crevices, baseboards, loose plaster, behind bed frames and headboards, beneath beds and furniture, and to bedsprings and bed frames. Do not apply to furniture surfaces or mattresses where people will be laying or sitting. Infested bedding should not be treated, but should be removed, placed in sealed plastic bags, and taken for laundering and drying at high temperatures.
There is another product called Phantom that can last up to 30 days and it can be sprayed in all of the places the the Cyzmic can be sprayed in plus it can be used on the tufts, folds, seams and edges of mattresses and box springs. Phantom has the benefit of being non-repellent which means that insects cannot sense that it is there so they cannot avoid treated areas. There is no known resistance from bed bugs to the active ingredient contained in Phantom.
As long as you are not spraying the Cyzmic CS on edibles of any kind, the Cyzmic is safe for you to spray on plants like trees, flowers and bushes without it harming them.
The mixing ratio for Cyzmic CS Micro-encapsulated Insecticide is 0.2 fl. oz. per gallon of water for maintenance treatments.
Cyzmic CS is an encapsulated insecticide, which means each bit of active ingredient is protected in its own capsule. This helps the active ingredient to stay stable for longer, especially in the harsh heat, sunlight, and rainfall many areas get during the Summer months when mosquitoes are most prevalent. Encapsulation also helps to distribute the product more evenly over surfaces like foliage, and it keeps the product in place better, preventing runoff. Since mosquitoes may only touch a leaf in a few small spots, encapsulated insecticides give us the best chance that a mosquito or other target pest will pick up a bigger chunk of that active ingredient more quickly. We also use less product per application, and applicators get less exposure to active ingredients . The only real disadvantage to a product like Cyzmic CS is that it costs more per application than Bifen IT. If you have a very large area to treat or need the extra flexibility of some of the additional pests on the Bifen IT label, then the Bifen may be a better choice for you.
There really is no reason to mix Cyzmic CS and Talstar P as they're both synthetic pyrethroids so there would be nothing to gain by mixing these products together. Mixing these two products would make the concentration too strong and instead may act as a repellent causing insects to simply avoid the treated areas prolonging the infestation.
