As good as Conquer at a cheaper price
By Bryan in Temple, TX on 08/28/2012
This concentrated form of esfenvalerate is wonderful (.42 oz.s per dose versus Conquer's 1 oz.) It's like getting another bottle for just a few dollars more. You can mix this with oil for fogging/space spraying and Actisol injecting into cracks and crevices. I'll definitely buy this product again in the future.

The price is right , However..................
By Ed in Delaware on 08/28/2012
I started using Fenvastar Plus today and immediately notice the strong odor it gave off. And that was while doing an exterior service. I don't plan on using it on any interior services because of the odor.

Works on Leaf cutter ants
By Richard in Thomaston, Texas on 10/25/2012
We have been infested with leaf cutter ants. I have been looking for something that I can control them with and found that FenvaStar Plus Esfenvalerate 8.4% has the ingrediant needed for that. I have a 15 gallon tank with a 12volt pump, I spray the top of the mound to kill the ants on top of the ground and then put the spray wand in the hole and pump about 1/2 gallon of mixture in to get it down to where they are living. I have found that I actually didn't need to pump the product into all of the holes as some of them interconnect under ground. I had an area approx 20 x20 ft that was covered with mounds. It has been 3 weeks since i made the first application. I only have had 4 new mounds appear, but outside of the area. I do not expect to totally get rid of the ants, but I am able to control them. This product also kills Fire ants and Harvester ants. Note, you can't expect the product to work if you don't use enough.

I was greatly impressed with the speedy delivery. The product Fenvastar is truly amazing. I did phone "do my own pest control" and they were most helpful. I will be ordering more product in the near future.
To kill a cutter ant
By Terry in Pleasanton, Texas on 08/13/2013
Pleasantly surprised to have positive results using this product to terminate cutter ants.
A real knockdown
By David in NJ on 04/30/2017
Fenvastar Plus is my personal favorite repellent. It is expensive, and has a medium residual, but it kicks butt on initial treatments. The smell is an issue if your sensitive, I would describe the odor as a paint thinner and walnut oil aroma. I usually don't use it indoors since it is oil based.

QIs Fenvastar Plus effective on carpet beetles?
Is Fenvastar Plus effective on carpet beetles even though it is not listed on the label? Fenvastar Eco has carpet bugs listed but I notice they have the same ingredients, just the plus has a higher amount of Esfenvalerate.
AWhile Fenvastar Plus will likely work for carpet beetles the product is not specifically labeled for carpet beetle control. Fenvastar EcoCap on the other hand has been tested for and is labeled for carpet beetle control.

QWhat is the best product to use for earwigs in CT? It seems everything is restricted here.
AFenvastar would be a good choice for you. Fenvastar contains the active ingredient esfenvalerate, is a low odor pest control product and is labeled for all major pests including earwigs. It can be applied using a hand pump sprayer into all cracks and crevices in woodwork and floors, underneath sinks, areas behind pipes, and in all places where these insects shelter. Fenvastar is safe to use in a home where cats live as long as you follow the product label. Keep cats out of the area while you are applying the product and they can return to the area as soon as it is dry.
QIf you use FenvaStar Plus Esfenvalerate 8.4% with the ULV fogger, when is it safe to return to the home?
AFenvaStar Plus Esfenvalerate 8.4% can be applied in a ULV fogger. You should stay out of the area during dispersement and return only when the fogging is complete and the area has been properly ventilated for a half hour.

QOrchard use and harvest interval
Minnesota's extensions program lists Esfenvalerate as good product for home Orchard use. However I dont see information about using this product in that context. What is the time from the last spray till the fruit would be safe for consumption(Harvest interval)? Or is this product not intended for that use?
AWe generally do not recommend using fenvastar Plus in Orchards. Please contact rockwell Labs 866-788-4101 to verify that you can or cannot use this product. You could also use something like Bonide Fruit Tree Spray that is intended for use on fruit tree.

QWhere are bees on the label for FenvaStar Plus Esfenvalerate 8.4%?
I use this at work for my company. It works amazing. The one question I have, is why are wasps, hornets, and yellow-jackets not on label?
A We are not sure of the exact reason why†FenvaStar Plus Esfenvalerate 8.4%†does not list bees, hornets and yellow jackets on the label as this information is not provided by the manufacturer. †It could be that it was not tested against these pests or that it was and was not found to be very effective against them.

QCan Fenvastar Plus Esfenvalerate 8.4% help with camel crickets?
I have a cave cricket in the basment in the garage and i foond it in the house to
A While Fenvastar Plus Esfenvalerate 8.4% is labeled for crickets, it is not labeled specifically for camel crickets. We would recommend Niban Granular Bait†.†This is the time of year that they are coming indoors looking for shelter as the weather starts to get cooler. They also love dampness and moisture. Outdoors these crickets hide in cluttered garages, near leaky gutters, underneath decks and in piles of leaves, Clearing away leaves under your desk and around your home, cleaning our your garage, ventilating crawl spaces, cutting back bushes, fixing leaky gutters and making sure your sprinkler is not hitting your house can deter camel crickets from nesting nearby, and ultimately invading your home.† †
