D-Fense SC Insecticide - Questions & Answers

D-Fence SC states on the label you can use up to 1.5 oz per gallon when treating a severe pest infestation or when longer residual is desired. Please refer to label for application details. 

D-Fense SC and Suspend SC contain the exact same active ingredient. Therefore they are the same product. We suggest alternating your chemical every few years to prevent resistance buildup which could be happening in your case. The each only kill the insects that contact a treated area as well. We would recommend reviewing our ant guide here to help eliminate them more effectively.

D-Fense cannot be used on animals. We do carry Permethrin SFR 36.8% and it is specifically labeled for use on goats for lice. Be sure to read the product label for full usage instructions.

D-Fense SC is an insecticide that will kill adult beetles. You can add an Insect Growth Regulator that is labeled for Dermestid beetles such as Gentrol IGR Concentrate to your D-Fense SC solution to help control the immature stages of these and other listed insects. Be sure you are removing any infested items and cleaning the area thoroughly before applying insecticides.

D-Fense SC is not labeled to be used in any type of fogger. It is labeled to be used as a crack and crevice treatment in a pump sprayer. The D-Fense dust should only be used inside the wall voids. We cannot recommend using our products off label. Please let us know if you have any additional questions.

To be honest, this time of year there isnt much you can do for the ones that are inside other than your current efforts of vacuuming them up. Stink bugs and similar beetles start making their way inside your home during the fall and emerge the next spring. To prevent them from getting in, you must spray around the window frames, door frames and eaves and edges of the home they could use as entry points every month from August through November and often December if you are in areas where winter hits later in the year. Once they are already inside, they will stay in crevices for the most part and only appear on warmer days or until spring rolls around. That explains why you see them on the windows of the sunny side of the home as that is what they are drawn to and they are trying to figure out how to get back out of your home. You can put insecticide dusts like Cimexa Dust down in crevices and cracks, around seals and in wall voids by removing the covers from plugs/outlets and light switch plates. You would apply a few puffs of the dust in the voids with a B&G Bulb Duster to get a coating the insects can crawl through and hopefully die from before you start seeing them out in the open crawling around. For spraying around the door/window frames inside and out in the fall the D-Fense SC would work great for your needs. 

D-FENSE SC may be mixed with latex coatings and oilbased coatings such as stains, varnishes and sealers for use to kill crawling and flying insects when exposed to treated surfaces.  Please see our Carpenter Bee Treatment article for more information about treating for this pest.

D-Fense SC should be applied 24 hours before you are expecting any rain, or before you plan to irrigate.  After 24 hours, it will be rainfast and you will not need to reapply after it rains or after you water. 

D-fense SC is not labeled for wheel bugs. Wheel bugs do not harm humans or plants that are in the area. They are a beneficial insect, therefore we do not make recommendations for products to get rid of them. 

We cannot sell 

D-Fense SC to New York, Alaska or Connecticut due to restrictions and regulations within those states.  

D-Fense SC is labeled for spiders so it would be effective on black/brown widows and brown recluse spiders. Please also take a look at our guides on How to Get Rid of Brown Recluse Spiders and How to Get Rid of Black Widow Spiders for some helpful info. 
 

D-Fense SC and most chemicals should be stored in a temperature stable environment between 45-75 degrees, and out of direct sunlight. 

D-Fense SC would be a good choice for monthly mosquito treatments to your lawn, bushes, trees, and shrubs on the property. For heavy mosquito populations, adding an Insect Growth Regulator like Tekko Pro IGR to  disrupt their life cylce and keep juvenile stages of mosquitoes from becoming reproductive adults.

Repeat outdoor applications every 21 to 30 days wll be needed during high pest season. Also adding a contact syngergist insecticide like ExciteR is a great way for immediate relief of mosquitoes. ExciteR does not leave a residual and will kill mosquitoes on contact or while the applicaiton is wet. These 3 products can be tank mixed together in the same sprayer tank for an all in one application.

We recommend to refer to our Mosquito Control Guide for further tips and information. 

You can use a product like D-Fense SC.  It’s a synthetic pyrethroid that can be reapplied on a monthly basis. You can use it at a rate of 0.75 – 1 oz per gallon of water for mosquito control. When treating for mosquitoes, make sure to spray the underside of the leaves on ornamental shrubs and trees as these are areas they harbor in. Keep in mind that one treatment will not get rid of all the mosquitoes. For high activity, we recommend adding an insect growth regulator, like Tekko Pro IGR, to disrupt their life cycle and keep juveniles from becoming reproductive adults. This also works great on ants, fleas and a variety of other insects.

D-Fense SC Insecticide is a top choice for general pest control and is professional insecticide that is not found in local stores.  It would be stronger than the consumer grade options in stores. It offers a 90 day interior crack and crevice residual and 30 day exterior residual for many common pests listed.

Both products are extremely similar in the sense that they have will have a 30 day residual outdoors & will need to be applied with an IGR for best control. However, permethrin is oil based while D-Fense SC is water based. We would also recommend looking over our mosquito guide for tips on controlling mosquitoes.

Depending on the speciifc insects you are targeting, D-Fense SC Insecticide is applied at 17.5 to 26 fl oz per acre or 26 to 39 fl oz per acre in 88 gallons of water (2 gallons of water per 1000 sq ft).

Please refer to the product label for more information. 

 

D-Fence once mixed and applied correctly as the label suggests, will not stain anything that water would not.  We would not recommend applying across window surfaces, as applications should be just around the window frames, edges etc.

We would suggest having a wet cloth to use so that you could wipe up any overspray before its dried.

If D-Fense SC was exposed to freezing temperatures for one night, simply bring the product back to room temperature as soon as possible, and shake the product well.

However, prolonged exposure to extreme temperatures and direct sunlight will degrade the effectivity of the active ingredient.
