Termidor SC can be applied twice a year (1 ft up and 1 ft out) up against the structure for a pest control barrier at 0.8 oz per gallon of water. It can be applied four times a year at 0.4 fl oz per gallon of water in the same area.
Termidor SC is applied 1 ft up and 1 ft out directly up against the foundation for a crawling insect barrier 2-4 times per year depending on the rate used (see product label for complete mixing instructions). If treating for subterranean termites, the product is applied in a 6 X 6 trench and in drilled holes up against the foundation. Please take a few moments to review our treatment article on How to Get Rid of Termites for more detailed information on a successful eradication program.
You should perform a liquid termite treatment in the ground to get the termites where they are entering the shed. To perform a treatment just as a professional company would do, please read our How To Do A Termite Treatment Article which explains exactly how you should treat your home properly. Doing a treatment like what is described in the article will not only take care of existing termites that you have, but it will also protect and prevent future termites from entering for about 7 years. Even though the article talks about a home, the shed is no different. You should dig a trench around the structure as described in the article below, as well as try to trench around individual supports under the shed if possible, if any exist.

Please let me know if you have any further questions.
Termidor SC is not labeled for root aphids. If you can let us know where you will be treating, we can recommend an alternative for you.
When applying Termidor SC as a foam, it is both the chemistry of the foaming agent and the pressurized application from the foaming equipment that generate the foam, so we must have both of these components to create a foam from a liquid insecticide concentrate.
Once Termidor SC has dried, it should not be harmful to people, pets or wildlife. It can be toxic for bees if they come in contact with treated areas once it has dried. To lessen this risk, apply in the morning or evening when bees are least active. Please refer to the product label for complete application instructions.
We actually recommend, if possible, to apply Termidor in a trench inside the crawl space. You will use the same method as you do around the entire structure.
