FenvaStar Plus, manufactured by Rockwell Labs, is an effective insecticide concentrate for commercial and residential pest control.
Its ultra-low VOC formula and low odor are designed to be sprayed, diluted with water, or fogged. FenvaStar is ideal for treating fleas, ticks, bed bugs, and other pests.
Tools Needed
To use FenvaStar, you must mix the product in a power sprayer or hose-end sprayer.
How to Use
- Step 1: Clear the area to spray by moving any furniture or food items from the area of application. For added safety, ensure no children or pets are allowed into the treated area until the application has thoroughly dried.
- Step 2: Before mixing the chemical, add proper safety equipment and/or attire for eye and skin protection. This would include safety gloves, eye protection, a long-sleeve shirt, pants, and close-toed shoes.
- Step 3: Add half a gallon of needed water to the sprayer, add chemical and Insect Growth Regulator (IGR) if desired for added effect, shake to mix, add the remaining half a gallon of needed water, then shake to mix thoroughly.
- Step 4: Spray the solution to cracks, crevices, voids, carpets, and behind-fix tires. Cracks and crevices include baseboards, corners, door frames, and window sills. When spraying furniture, it is best to spray as you are walking out of the room so you do not walk over the treated area while still damp.

FenvaStar Plus can be used in and around homes and lawns, food and non-food areas, including Schools, Warehouses, Office Buildings, Apartment Buildings, Theaters, Hotels, Motels, Kennels, Food Processing Plants, Food Service Establishments, Truck Trailers, Railroad Cars, Food Manufacturing and Warehousing Establishments.
Do not spray plants used for food or feed.
