Bifen IT - Questions & Answers

We are not sure what type of worm would be considered a "red worm" as you have described.  If you are referring to earthworms, Bifen IT is not labeled for earthworms, because they are a beneficial but it may cause harm to them if they contact a treated area.  Though they are pretty protected by the mucus on their bodies. This small amount of product needed to kill tiny insects would not be enough to harm a bird if they were to ingest a worm that would have contacted the product.

We do sell professional Roach Bait Gel and Ant Bait Gel.  Follow the links to which ever one you are inquiring about. We also carry bait granules and insecticide granules for pest control. Please read the labels for specific instructions on application.

Unfortunately you did not mention what pest you are trying to treat in your yard so we can not be very specific. The Bifen IT label does say that you can repeat applications as often as every 7 days outdoors but most customers do not repeat applications more than once a month for most pests. Again the usage rate of Bifen IT will vary greatly depending on what type of pest your are trying to control. The Bifen IT product label recommends 0.25-1.0 fl oz per 1,000 sq ft for most pests outdoors. You can find the usage rate tables starting on page 12 of the product label.

Spring tails can be tough to eliminate because they reproduce very quickly. In almost every case where people have spring tails they also have a moisture problem such as a leaking or sweating pipe, poor ventilation in their crawl space, lots of wet mulch right up next to their house, etc. You must locate and correct the moisture problem to get rid of the spring tails, insecticides alone will not do the job. We do carry Bifen L/P granules and Bifen IT liquid, both of which can help you to reduce the numbers of springtails.

Absolutely. Bifen IT can be used on just about any type of grass as long as the grass will not be used as animal feed later.

Since different people can have varying reactions to the same chemical there is no way for us to be able to say for sure that any one person will not have a reaction to a specific insecticide. We can say that we have never had a report of any type of reaction to the Bifen IT when used as directed on the product label. Be sure the person with asthma is out of the area while the product is being applied and they can come back when the area is completely dry. You may also want to contact the asthmatic persons physician prior to the application just to be sure there will be no issues.

You can apply Bifen IT indoors so long as you make sure none of the spray winds up in the pond. The very small amount an insect may have on its body should have no effect at all on anything in the pond. If contaminating the pond is still a concern for you there is a product called Essentria IC3 that can be used around water without worry of hurting any of the aquatic animals you may have. Essentria IC3 is a broad-spectrum natural insecticide that works just as well as the synthetic insecticides but without the aquatic toxicity issue.

We recommend using the bait products first and then following up with the Bifen IT. If you spray the Bifen IT in the same place as you use the baits you will make the baits less appealing to the ants and you risk the bait not getting back to the colony because the ants could die too quickly.

You didn't mention what type of garden you have. Is it a flower garden or a vegetable garden? If it is a flower garden Bifen IT should work very well to help eliminate the blister beetles. Bifen IT is not labeled for use on edible plants. If it is a vegetable garden you will need to use a product that is labeled for use on edible vegetation such as Sevin or Natural Guard Insecticidal Soap. Be sure you read the product label of the product you choose before purchasing to make sure the plants you need to treat are listed. Product labels are on individual product pages under the picture of the product. You should also note that we didn't find any products that were specifically labeled for blister beetles so we recommended products that eliminate general garden pests. When pests are not specifically listed on product labels it is usually because these pests do not damage enough crops as to be agriculturally significant.

Bifen IT can be sprayed onto and into the shakes to provide some relief from the silverfish. Be sure to use the highest usage rate of 1 oz of Bifen IT per gallon of water for the fastest knockdown and the longest lasting residual. You will need to reapply once a month to keep up the barrier.

Bifen IT is an insecticide and does not have anything in its formulation that would keep mammals out of a garden. We do carry several repellents that would better suit your needs. You can checkout our animal repellents here : Animal Repellents

It depends.  The whole key to getting rid of springtails is their breeding source.  You have to find it.  Usually they breed under the slab and enter the home through small cracks.  Unfortunately when they breed under the slab the product you apply on top of the ground will not make it to them.  The slab has to dry out and you have to do whatever you can to prevent moisture from getting under the slab.  Usually springtails are breeding because of too much mulch around the house, grade against the house is not going away from the house and water puddles up, downspouts are not going away from the house, etc.   Getting rid of springtails is a moisture management issue usually and not something that pesticides can get rid of alone.

You must keep Bifen IT applications outside of the root zone of the vegetable plant according to the Bifen IT product label. Spraying within a foot of edible vegetation is usually too close.

Bifen IT is labeled for gnats. Gnats must land on treated areas to be killed by the product. Please read the BIfen IT product label for complete usage instructions.

We do not recommend outside of the product label. The manufacturer states to use no more than 1 oz per 1 gallon of water. This product is a residual based product. The residual outdoors is 30 days indoors 90 days. Even if you were to use 4oz, you would still need to reapply per the product label of 30 to 90 days.

We do not recommend using Bifen It in or on fruit bearing trees. Please contact Control Solutions to see if they can help you trouble shoot this. You can reach this manufacturer at 281-892-2500.

You cannot use Bifen IT is a propane fogger. The heat will detroy the effectiveness of the product. Youc an use the product in a mist blower such as the Solo 451.

Bifen IT is labeled for fire ant control and will help help eliminate fire ants when used as directed on the Bifen It product label: fire ant control is optimized by combining broadcast applications that will control foraging workers and newly mated fly-in queens with mound drenches that will control existing colonies. If the soil is not moist, then it is important to irrigate before application or use a high volume application. Apply broadcast treatments at 0.5 to 1 fluid oz. per 1,000 square feet. Use enough finished volume to penetrate thatch or sod. Treat mounds by applying 1 oz Bifen IT per mound in 1 to 2 gallons water by sprinkling the mound until it is wet and treat 3 feet out around the mound. Use the higher volume for mounds larger than 12”. Treat mounds with sufficient force to break their apex and allow the insecticide solution to flow into the ant tunnels. For best results, apply in cool weather (65 - 80˚F) or in early morning or late evening hours.

Since the Bifen will be used topically for general pest control it should not interfere with a trenching treatment done using Termidor SC.

Bifen IT will kill termites that come in contact with the chemical. To eradicate termites you want to use a product that has a transfer effect. Termidor SC is a great product to use to treat termites. Please see our Termite Control Page. Scroll to the bottom of the page and find information on identification and treatment for termites.
