Cy-Kick CS is a great product and will do a great job towards helping you to get rid of roaches. For best results, we also recommend that you use a roach bait gel to help get rid of roaches in places where you cannot spray, along with an insect growth regulator (IGR) which helps stop the roaches breeding cycle. You may want to consider using one of our Roach Control Kits, as they contain all of these products together. Pets and people need to be kept out of the area while products are being applied, but can return as soon as all surfaces are fully dry. Please take a moment to look over our article on How to Get Rid of Roaches for more information on how to do a complete treatment for roaches.
We do not recommend storing mixed Cy-Kick CS. You would want to either use the entire gallon within 24 hours of mixing or spray the excess along the foundation of your home.
Cy-Kick CS as well as any other products are not meant to be stored longer than 24 hours once mixed with water. Most sprayer manufacturers warn against storing insecticides inside the sprayer. Storing liquids (even plain water) inside the sprayer can cause the rubber components to deteriorate quickly and make the sprayer inoperable. Only mix exactly what you can use and discard any left over solution outside in the woods or in a place that is not near any bodies of water and thoroughly rinse the sprayer after each use.
Our number one recommended product for customers in the Arizona area is Cy kick CS. Cy-Kick CS creates a thick barrier of microcapsules that is impossible for insects to cross without being exposed to a lethal dose of insecticide.
Cy-Kick CS could be applied for mosquitoes. However, because it is microencapsulated it would not have a very quick kill initially because the microcaps slowly release insecticide over time. This product has a long residual, but not a good first punch. Our most popular product for mosquito control actually combines a good quick knock down with a long residual, and it is called Talstar P. We have a great guide here as well Mosquito Control Article. We are not aware of anything being added to Cy-Kick nor the product that you mentioned. Being a microencapsulated product it would generally hold up very well on surfaces alone.
These products should not be mixed together. There is no valid reason to mix Cy-Kick CS and Bifen IT together. Bifen IT is a synthetic pyrethroid and Cy-Kick CS 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.
Cy-Kick is toxic to bees and fire flies. You would want to be sure to apply when bees are not pollinating. Or in areas that fire flies may not be populating.
With most concentrates including Cy kick CS, you want to be sure to use all mixed solution within 24 hours of mixing.
