Q

Is 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.

A

While 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.

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.

Per the product label, this product cannot be used in a ULV Fogger for residential homes.

If using an aerosol fogger, the unit needs to product particles of aerosol size thirty (30 microns, or less) and would be applied as a crack and crevice application behind all equipment, appliances, cupboards, or any dark harborage areas. This can then treat as a space spray directing the spray towards the ceiling and upper corners of the room at the rate of one (1) ounce diluted spray per 1,000 cubic feet of space.
