Permethrin SFR 36.8% is labeled for ticks and can be used in your lawn. The product should not be used within the drip line of the garden. We normally recommend using it at least 2-3 feet away. Once the product is dry, it is safe for your children to go into the lawn. Please let us know if you have any additional questions.

Because of the natural boring behavior of the beetle they are protected from topically applied insecticides and systemic insecticides (those injected into the tree or applied as a root drench) have proven ineffective for pine beetle infestations. Healthy trees can be protected before the beetles attack by topically spraying them with a synthetic pyrethroid like Permethrin SFR.  Unfortunately there is no easy solution when it comes to pine beetles. Infected trees should be cut down (before the newly hatched beetles fly out of the trees in the spring/summer) and the wood burned or chipped, while other still healthy trees should be sprayed annually to protect them.  The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations. You should contact your local cooperative extension office to find out the best time to start spraying in your region.

We would recommend that you contact the manufacturer, Control Solutions for the most reliable recommendations for such a sensitive concern. Control Solutions may be reached at (800) 242-5562.

Permethrin SFR 36.8% is not labeled to be used in a misting system.

A better option would be Sector Misting Concentrate. Sector provides quick knockdown, kill and residual control of flying insect pests including mosquitoes, flies and other insects. he residual of the chemical will not harm most common ornamental plants and shrubs, so the product is safe for use in backyards near lawn and landscape areas. Can be used in automatic spraying systems, ULV foggers, mosquito misting systems, cattle barns, animal quarters, dairies, poultry houses, warehouses and more.

Permethrin SFR 36.8%  will not treat for Click beetles/Wire worms. It is hard to find a treatment that is labeled for these pests. First, be sure to remove or clean up any piles of debris in the yard or patio/deck. Research shows that cutworm treatments have proven effective on Click beetles.We would recommend Cyonara RTS.  It comes in a convenient bottle that hooks up to your hose and is labeled to apply in your garden.  It will not only take care of cutworms, but many other pests that might be in your garden.

There is no valid reason to mix Temprid SC and Permethrin SFR 36.8% together.  Permethrin SFR 36.8% is a synthetic pyrethroid and Temprid SC already contains a synthetic pyrethroid, so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.

Permethrin SFR is diluted with water. The dilution rate is 1 2/3 fl. oz. per gallon of water.

Yes, Tengard SFR and 2,4-d can be mixed together when spraying. It is recommended that you do a small tank mixture first to ensure that there is no clumping. 

Permethrin SFR 36.8% per label can be applied indoors to cracks and crevices and outdoors. 

Permethrin SFR can be used to drench ant mounds in animal areas. Per the product label: "Apply 1-2 gallons of emulsion to each mound area by sprinkling the mound until it is wet and treat a 4 foot diameter circle around the mound. Use the higher volume for mounds larger than 12 inches. For best results, apply in cool weather, such as in early morning or late evening hours, but not in the heat of the day."

If you are treating in a grazing area or pasture, then we would suggest doing the same application using Essentria All Purpose insecticide, which does not have grazing restrictions.

Permethrin SFR 36.8% can be applied with a hose end sprayer. Same application rates apply.
