D-Fense SC is applied quarterly (every 90 days) to interior cracks and crevices.
D-Fense SC would only be used on a Christmas tree if you were growing it in your yard. We would not recommend spraying on one you have set up in your home.
D-Fense SC is a great choice as part of cluster fly control. The best time to treat for this overwintering pest is in late Summer and Fall when this pest is trying to move indoors to stay warm during the winter. You can treat during warm spells and in the Spring as cluster flies move to go back outside, but you will not be able to completely eradicate them during this time. We also recommend sealing up cracks and crevices around windows, doors, and light fixtures where these insects may be able to enter or hide. Many folks will also use a fly light to help catch these insects in indoor areas.
Per the manufacturer, the residual of D-Fense SC if used in an area that doesn’t receive rainfall or direct UV light can be up to 6 months. In areas that do receive UV light and rainfall, the residual can last up to 60-90 days.
We recommend that you apply D-Fense SC with a synergist such as Exponent for a quicker kill. Exponent will increase the speed of kill and level of control of pyrethroid, D-Fense SC. We also offer Cimexa Dust with a dust applicator for the wall voids,etc. We recommend that you treat monthly on the exterior with D-Fense SC (as weather permits) especially during July-November and the spring (when the exit hiding areas due to warmer weather). The ones that make their way inside should be vacuumed. Exclusion is a great way to help keep them outdoors as much as possible. The exterior areas can be treated with D-Fense SC and you can incorporate a surfactant (in replace of dish soap). Please take a few moments to review our treatment article for a successful eradication program on How to Get Rid of Boxelder Bugs.
D-Fense SC is applied at 4 to 8 oz/100 gallons of water for ornamentals. Apply when pests become evident. Thorough coverage is required for best results. Apply with sufficient water to ensure coverage of upper and lower leaf surfaces. If you are doing an outdoor perimeter application page 21 and 22 of the product label suggests using either 0.25 fl oz per gallon, which would be 25 fl oz per 100 gallons or 1 oz per gallon, which would be 100 fl oz in 100 gallons of water.
D-Fense SC as well as most insecticides are the market these days are clear drying, non staining insecticides that you mix with water and spray in areas where pests are a problem. This will not damage the home no matter what material it is made out of and will not stain or cause discoloration or structural problems.

D-Fense SC has a three year shelf life from the date of purchase if stored away from extreme temperatures. It should only be applied 25 ft away from water. We do carry Essentria IC3 that can be applied to the dock areas for spider control.
We would recommend filling your sprayer 1/2 full of the water, put in the D-fense SC, put in the IGR, fill up the rest of your tank with water and agitate, so that all of the products are thoroughly mixed together, and spray.
