Bifen IT is not a contact kill product, it is a residual product that can take a few days to start killing the insects that you are treating for. After you apply it to your lawn, it is important to avoid mowing and watering for at least three days. This gives the product time to do what its designed for. They still may move but will eventually die.
Bifen IT is one of our most popular products for Chinch Bug Control. The key is to use lots of water to carry the Bifen IT down to the thatch layer underneath the grass, where the chinch bugs do the most damage. Please read the product label for proper application instructions.
Bifen IT will treat Chinch bugs at the sign of damage. Dilute at 1oz per gallon water. Please also review our Chinch Bug control page.
Yes, Bifen IT is labeled for earwigs. Spray indoors around the baseboards, door frames, window frames, under appliances and places where utilities (cables, pipes, wires) enter into the structure. Outdoors you should spray a 3 foot band around the bottom of the foundation and then spray another band that is several feet wide out onto the ground immediately adjacent to the foundation, door frames, window frames, and places where utilities enter into the structure. If you have mulch up close to the foundation , you should rake it back at least 6 inches and turn it frequently to get rid of the moisture it can hold. Bifen IT can also be sprayed by the play set, but not on the play set.
Bifen IT will kill wasps that it comes in contact with. The mixing ratio is 1 fl oz per gallon of water.
Bifen IT is specifically labeled for a number of medically significant spiders including Black Widow, Brown Recluse and Hobo Spiders. It is important to remember that Bifen IT does not give an immediate knockdown but instead works over a period of several hours to kill spiders that have come into contact with the product. Bifen IT will also help to get rid of the insects that spiders feed on and that will help to stop new spiders from moving in. Indoors, spray around all baseboards, door frames, window frames, under appliances, in closets and storage rooms and in areas where utilities enter into the structure. Outdoors you should spray around the bottom of the foundation, on the ground adjacent to the foundation, door frames, window frames and places where the utilities enter into the structure. Brown recluse spiders are a bit trickier to eliminate because they often stay hidden in areas where people do not or cannot spray. We recommend that in addition to the Bifen IT, you also use glueboards in areas where spraying would not be appropriate and to help monitor the infestation (cabinets, closets, under furniture, storage areas)
Bifen IT is labeled for roaches can be used to help eliminate a roach infestation. However, it should not be the only product that you use as roaches are difficult to treat and usually more than one type of product is necessary. We would recommend using one of our Roach Control Kits to ensure that you have everything you need. You may also want to take a look at our Roach Control Guide for more information on implementing a complete treatment program.
Bifen IT should NOT be applied to bedding, mattresses or carpet to treat head lice. There is no reason to spray a residual insecticide around your home to treat for head lice. The adult head louse cannot live more than one or two days with out a blood meal. Nits cannot hatch if they are not on a human host, because their temperature cannot be maintained properly and the nit will not be viable.
Clothing, pillows, blankets and sheets should all be washed in hot soapy water and dried for at least 30-40 minutes on high heat in the dryer. Non washable items (stuffed animals, dry clean only clothing...) should be put in the dryer on high heat for at least 30 minutes. Any other items should be sealed in bag for at least 7-14 days.
Carpets and other flooring should be thoroughly vacuumed and the vacuum bag sealed in a plastic bag and thrown away. Furniture can be sprayed with Sterifab. Sterifab is an alcohol based product that includes a synthetic pyrethroid that is safe to spray on furniture and mattresses. Sterifab dries in about 20 minutes and does not leave any residual on the surface that is sprayed.
The coverage will depend on the type of pest you are treating for and the area that is being treated. Please check the Bifen IT product label to see what concentration and coverage rate your situation calls for. One pint of Bifen IT will make approximately 16-48 gallons of diluted solution and one quart of Bifen IT will make approximately 32-96 of diluted solution. If you need help figuring out the concentration please call customer service at: 866-581-7378
Bifen IT will help control boxelder bugs. You want to mix at 1oz Bifen IT per gallon water. Bifen IT will kill the Boxelder bugs after they come in contact with the treated area. Depending on what stage they are in the life cycle will determine how long it will take to kill them. The residual of Bifen IT can be up to 2 months, but it is best to reapply every 30 days.
While Bifen IT is labeled for bedbugs, we recommend that you use a combination of products to effectively eliminate them from your home. We have put together Bedbug Kits that come with all of the products that you will need. Please see our Bed Bug Pest Guide for more information about treating for bed bugs.
