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.
Cy Kick CS is a water based product and should not cause damage to any surface that water would not damage.
Yes, Cy-Kick CS will kill just about any spider that it is sprayed. Spiders are very difficult to control however and most residual insecticides like Cy Kick CS will kill any spider that it is physically sprayed on, but new spiders entering the area are very difficult for any insecticide to control. This is because spiders bodies are high off of the ground and they do not groom their legs like other insects do. How these products mainly control spiders is that they kill the spiders food that is around, all of the other bugs, and if there is no food around, then the spiders will not want to be in that area anymore. For more information, please take a few moments to review our treatment article on How to Get Rid of Spiders.
The main difference is that the Cy-Kick CS is a microencapsulated suspension. Micro Encapsulation means that each droplet of insecticide is encased in a protective microscopic capsule, which provides a long residual even in direct sunlight. Micro cap also means the product can be more easily picked up by the tiny hairs on insects and especially flying insects. So, while both the Bifen IT and the Cy-Kick CS are great products there are some instances where Cy-Kick CS is a bit more effective such as spider and scorpion control and on outdoor surfaces that are exposed to the elements.
Cy-Kick CS is labeled for a contact kill only for fleas. According to the product label, Cy-Kick CS will not leave an effective residual for continued control of flea populations. We recommend using the products contained in our Outdoor Flea Kit for best results. This kit contains Onslaught which kill the biting adult fleas and Martins IGR which will help stop juvenile fleas from reaching a breeding cycle.
