Bifen IT will kill Cicada Killers. We also recommend to apply Delta dust in the holes in soil.
When using Bifen IT to treat for soil dwelling pests such as sob webworms, the rate is not per gallon of water but per 1000 sq ft as you would use sufficient water to cover the target area and get the product to the pest. Per the product label: To accomplish uniform control when applying to dense grass foliage, use volumes of up to 10 gallons per 1000 square feet. You would use 0.18 - 0.25 fluid oz. per 1000 sq. ft for sod webworms. Higher treatment rates (up to 1 fluid oz. per 1000 square feet) may be necessary if high pest pressure exists and if the grass is maintained taller than 1 inch.
In general 1 gallon can cover 1000 sqft but for sod webworms the amount of water needed could be higher depending on the grass foliage, equipment used, how fast you walk, etc.
There are a few ways to keep the number of gnats down. You can invest in a misting system that periodically sprays a pyrethrin insecticide in your yard. This system is a lot like a sprinkler system. We do not carry the actual mister system but we do carry the insecticide that is used in it called Riptide. If you want to get something you can just spray you can try Talstar P. Gnats that land on the treated areas will be eliminated. Talstar P will not repel the gnats from the area nor will it kill the gnats that do not land on the treated areas.
Bifen IT is a great product labeled for over 75 types of insects, including scorpions and especially mosquitoes. Mix 1oz Bifen IT per 1 gallon of water and apply as a perimeter treatment or broadcast treatment over the entire property. When treating for mosquitoes, it is important to focus on the undersides of leaves, bushes, trees, shrubs, decking, eaves, etc as this is where mosquitoes will hide during the day. Pay attention to damp areas and possible consider using BTI Mosquito Dunks in areas where you have standing water.
Bifen IT used inside the home as a crack and crevice treatment will last 90 days and 30 days outside the home as a perimeter or broadcast treatment.
You can spray plants with Bifen IT on days with high temps but you should refrain from spraying during the heat of the day. Instead, restrict applications to very early morning or late evening. This will prevent the sun rays from scorching the plants while they are still wet.
We do not ship internationally at this time. We apologize for any inconvenience.
Bifen IT is labeled to treat for clover mites when used accordingly. Clover mites are barely smaller than a pinhead. You may notice clover mites as dark red moving specks which occur in large numbers. They are generally found crawling aroudn doors, windows, sidings, curtains, or furniture. Be sure to treat the ground at least 5-10 feet from the structure where you are seeing the clover mites.
As long as Bifen IT was applied as directed on the label and watered in as required for chinch bugs (at least 0.25 inch of irrigation) after application, you can go ahead and water in the fertilizer. It will not move much farther into the soil as it is designed to bind to the soil. If more water was used that would just have pushed it down into the soil better and will be fine.
