Adding a surfactant to Bifen IT outdoors does help the product adhere and increase effectiveness during the residual period.
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.
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.
Yes, Bifen IT can be used in a hose end sprayer. You will use 1 fl. oz. of solution and 5.5 ml of Nyguard IGR per gallon of water. You will put the concentrate directly into the cannister, and the tube will automatically use how much you have on the dial. It will disperse with each gallon that comes through the hose. You will need to be as accurate as possible when using this method. Please let us know if you have any additional questions.
Bifen IT is an insecticide that will treat for ticks as well as several other labeled insects. It does not act as a repellent. When applied to your yard at the proper mix rate, insects can not detect that the product is there. The insecticide leaves a residual that kills the insects that come in contact with it.
Bifenthrin and Bifenazate are used to treat different types of insects. Bifenthrin is mainly for general pest control use and is an ingredient in products such as Talstar P and Bifen IT. Bifenazate is a type of miticide and is an ingredient in products such as Floramite SC and Sirocco Miticide. We would not recommend rotating these two products for mite control. Bifenazate is a good active ingredient for spider mites, as well as Abamectin, which is the active ingredient in Avid 0.15 EC.
We recommend removing the Hermit Crabs from the rooms till after the application of Bifen IT has had time to dry.
Bifen IT could harm lightning bugs/fireflies if they land on a treated surface long enough to receive a lethal dosage.
Bifen IT is not designed to kill on contact and even when you spray an insect directly it can take several minutes or longer to kill it. It will help to kill the ones that contact a treated surface as well as their food source, but how long it takes to kill after application depends on age and health of the insect, how long after application they contact the treated surface and how long they spend on the treated surface. Spiders themselves are harder to kill as they do not groom themselves and have the long legs to keep themselves off the ground and in more contact with a treated surface. We have a great guide here for treating spiders that might also help. If you are going to be spraying spiders directly each time, you could add a product like ExciteR to Bifen to give it a faster initial knockdown only.
