Yes, you can mix an insecticide like BIfen IT and a fungicide like Honor Guard PPZ together in the same tank as long as niether product label prohibits such mixtures. Be sure always to follow the more restrictive product label and to plan your dilution rates correctly for each product in the volume of water you are using. We suggest a small jar test before mixing a large amount of products together for the first time.
Bifen IT may kill bed bugs that contact the treated area. Keep in mind we would not recommend this product for Bed bug control as certain strains are resistant to the active ingredient. Please check out our Bed Bug Guide. You will find the "How To's" in bed bug control and also a listing of our very effective kits.
Bifen IT and Pivot 10 IGR should NOT be applied in a thermal or ULV fogger. It should be dispersed in a hand pump sprayer, backpack sprayer, hose end sprayer or mist blower. We do carry thermal fogging concentrates that would be fine to apply.
They should not be present during application or while it is wet. You should only apply Bifen IT to the listed areas on the product label per page 13.

According to the Bifen IT product label, Apply 1 fl. oz. per 1,000 square feet when using broadcast treatments. For mound drenches, dilute 1 teaspoon of Bifen IT per gallon of water and use 1 to 2 gallons of finished dilution using sufficient force to penetrate the top and allow dilution to flood ant channels. Treat a four-foot diameter around each ant mound. Application should be made in late evening or early morning when it is cooler (65° - 80° when insects are most active. NOTE: A spray rig calibrated to apply 1 fluid oz. per 1,000 square feet of Bifen I/T in 5 gallons per 1,000 square feet contains the equivalent dilution (1 teaspoon per gallon) required for fire ant mound drenches in the spray tank.
Yes, Bifen IT is labeled for bees and can be used indoors and outdoors around the perimeter of your home. The mixing rate is 1 fl oz per gallon of water. Bifen IT can be reapplied every 30 days as needed. This is a residual so it will not kill them on contact. Once they come in contact with the treated area, they will die within a few days.
Bifen IT will not treat for roundworms in a yard. We do apologize but we do not carry a product for the lawn that is labeled for roundworms and we are not aware of any products available that would take care of this issue.
Generally it is necessary to take non chemical steps to treat this. Keeping dogs from a contaminated area for at least 1 year will prevent infestation and if that is not possible then removing and replacing the soil in area. Removing feces from the area as well when dropped is needed as well.
Bifen IT is not labeled for slugs or snails so we would not recommend it. Instead you can use a product like Monterey Sluggo Plus Snail & Slug Killer
Bifen alone will not eradicate fleas. You will also need to mix in an IGR to break down the reproductive cycle. Bifen kills the adults that come in contact with it, but then you still have the immature fleas growing and then reproducing. It is a constant battle without the IGR. We recommend Nyguard. Treatment should be reapplied after 14 days if needed and may take 2-3 or more applications. Humidity will not effect the Bifen, it can last up to 30 days on outside surfaces.
