Alpha-Cypermethrin CS 90-Day Residual BASF Professional Grade

More potent than standard cypermethrin

Alpha-cypermethrin is the active isomer of cypermethrin — more potent per milligram, faster knockdown, and often effective where standard cypermethrin formulations have lost efficacy due to resistance.

Pesticide — read label before use

BASF Fendona CS is a professional-grade insecticide concentrate. Always read and follow label directions. Keep people and pets off treated areas until dry. Avoid application near water bodies, storm drains, and pollinator habitats.

Why we recommend this

Fendona CS is our pick for accounts with heavy pest pressure or suspected pyrethroid resistance. The alpha-cypermethrin active ingredient is more potent than standard cypermethrin and often delivers results where other products have plateaued. Backed by BASF — one of the most trusted names in professional pest control chemistry worldwide.

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.

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.
