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 safe for dogs to be around after it has dried. approx. 2 hours.
Cyfluthrin belongs to a class of insecticides known as synthetic pyrethroids. Synthetic pyrethroids are man-made insecticides created to mimic the chemical properties of the naturally-occurring insecticide pyrethrum, which comes from the crushed petals of the Chrysanthemum flower. Synthetic pyrethroids, like cyfluthrin, are often preferred to the real thing as an active ingredient because they offer the added bonus of remaining effective for longer periods of time, sometimes up to 3 months.
Cypermethrin belongs to a class of insecticides known as synthetic pyrethroids, found in Cynoff EC, Cynoff WP, Cyper TC Termiticide, Cyper WP, and Demon WP pesticide concentrates. Synthetic pyrethroids are man-made insecticides created to mimic the chemical properties of the naturally-occurring insecticide pyrethrum, which comes from the crushed petals of the Chrysanthemum flower. Synthetic pyrethroids, like cypermethrin, are often preferred to the real thing as active ingredients because they offer the added bonus of remaining effective for longer periods of time.
