Bifen IT is available for licensed professionals to apply in New York State. We are not able to ship to homeowners but whether you could legally use it would be something you need to ask of the local department that handles pesticide regulations.
There is no waiting period to apply Bifen IT after aeration or seeding.
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.
Bifen IT is for insects only and will not treat fungus or other causes of spots on plants. It is important to identify the disease on your plants so that you can select a product that will work for your needs. You can contact your local cooperative extension office and speak to the master gardener on staff for help identifying the type of disease on your plants
Bifen I/T is a great product for earwigs and a large variety of other insects as well. You will spray Bifen indoors around baseboards and cracks and crevices, and outdoors around window and door frames, and around the foundation of the home 2-3 feet up on the side and 2-3 feet out on the ground. Earwigs like moisture and dark areas so if you have any mulch or pinestraw against the home or close by in the yard, turn those areas to help dry them out and soak them down with the Bifen to help kill anything living there. Children as well as anyone other than the person applying the product need to be out of the area being treated while the product is being applied and until everything is fully dry. Once all surfaces are dry it is completely safe for everyone to return.
You do want to spray Bifen IT over the sod periodically to keep the rest of the population on top of the new sod down.
We recommend removing the Hermit Crabs from the rooms till after the application of Bifen IT has had time to dry.

Bifen IT is an insecticide that will treat for ticks as well as several other labeled insects. It does not act as a repellent.

We do not recommend mixing together two pyrethroids such as Bifen IT and a permethrin product. These products are too similar, and you could create a repellency issue rather than allowing insects to actually contact the treated areas. If you want to add something to Bifen IT for faster intiial knockdown, then we suggest a pyrethrin and/or PBO product such as ExciteR Insecticide.
When treating for chinch bugs with Bifen IT, it is recommended that you do a second treatment 21-30 days after the first treatment. You will use 1 fl. oz. of product per gallon of water. This will treat 1000 square feet. Be sure to water the product in at least 0.5 inches after it has been applied.
Yes, Bifen IT can be used with an IGR like Pivot and a synergist like Exciter for a faster knockdown of insects such as mosquitoes. There would be no valid reason to mix Cyzmic CS and Bifen IT. You would want to use one or the other.
