BASF quality — outstanding residual
I've used a lot of professional insecticides over the years and Fendona CS is one of the best. The alpha-cypermethrin formula hits harder than standard cypermethrin and the controlled release keeps it working for months. Sprayed my perimeter in April and still seeing zero pest activity in late June. Excellent product from a company that knows pest control.

Solved a persistent cockroach problem
Had German cockroaches in the kitchen that nothing else could eliminate. Did a thorough crack and crevice treatment with Fendona CS and the problem was resolved within a week. The controlled release formula keeps working long after the initial application — haven't seen a cockroach in three months. Highly recommend.
Pest Control Professional
Go-to product for tough accounts
Fendona CS is my first choice for accounts with heavy pest pressure or resistance issues. The alpha-cypermethrin active ingredient performs differently than standard pyrethroids — it often works where other products have failed. The BASF controlled release technology is top-tier. This is a serious professional product.
