Unfortunately, Talstar P is not labeled to treat fruit flies. Fruit flies are attracted to rotten or fermented fruit and vegetables not house plants. However, they can also make homes in drains, garbage disposals, mop buckets, garbage cans, and recycle bins. Even something as small as spilled juice under your refrigerator can be a home for them; all they need is a thin layer of organic material.
Getting rid of fruit flies doesn' t have to be difficult. Cleaning up is the most important step in getting rid of them because they are naturally drawn to overripe, rotting, or spoiled produce. Therefore, merely throwing out such items or storing them in the refrigerator or sealed containers will lead to a drastic decline in the number of fruit flies, even without any further action on your part. Also, regularly rinsing out your garbage cans and recycle bins.
There are several different priduct you can use to get rid of fruit flies. Beccause they are flying insects, one of the best ways to kill fruit flies in your house is to use a fruti fly trap like the Vector 960 Fruti Fly Trap. Besides fruit fly traps, there are many different fruit fly sprays that will aid you in killing them as well such as 565 Plus XLO.
If you are only seeing flies around the indoor plants, then you may actually have fungus gnats, for which you could treat the plants with Talstar P. The most important step to eliminating fungus gnats is to avoid over-watering the plants, and to allow soil to dry out to reduce their food source and breeding environment.
Yes, you can apply Talstar P with a hose-end sprayer.
Talstar P Professional Insecticide should not be applied using a hose end sprayer when treating lawns, landscape beds, trees, etc. The liquid concentrate is too thick of a liquid and would clog the hose end sprayer. In a handpump or backpack sprayer, you can use the 1fl oz of Talstar P in 3 gallons of water over 1000 sq ft to insure adequate coverage.
Talstar P can be used to help control cluster flies indoors and outdoors. If the cluster flies have already made their way indoors, they will be harder to control because they usually hide in a wall void or other inaccessible area and are only visible when the house warms up. If the cluster flies are in an attic or drop ceiling or other dark area, a fly light would do a great job controlling the population. Using small fly lights such as the Fly Web in the house would also help to catch the flies. Spray Talstar P directly on baseboards, window frames, door frames, and places where utilities (pipes, wires, cables) enter in to the building and any other crack, crevice or gap where insects can enter.
