In a cold/ULV Fogger, you can dilute concentrates like EcoVia EC with either water or with oil. Typically you would dilute with water whenever possible outdoors to reduce the risk of phytotoxicity on the plants you are treating. Per the product label, use up to 0.25-1.5 fl oz of product per 1000 sq ft of ground surface area, or up to 10-60 fl oz per acre. It sounds like you will likely need to dilute the product to apply at this rate if your fogger is applying product that quickly.
EcoVia EC is a great choice if you are seeking a natural concentrate to mix with water and apply to outdoor areas. You may mix up to 6oz of EcoVia EC per gallon of water depending upon application site and insect.
EcoVia EC does not have restrictions for use around animals or aquatic life as long as the product is applied according to the label instructions. You should not apply directly onto animals, and we do recommend trying to spray when animals such as tortoises are not present in the direct application area for extra caution.
You would treat the Solo Sprayer? as you would any other backpack or hand held sprayer and rinse out the tank and blower with clean water in a triple rinse method. If cleaned properly between uses of any product including EcoVia IC, it will not clog the unit or cause any damage. Please let us know if you have any other questions.
EcoVia EC should not damage or stain the siding when used as directed on the product label and we have not heard compliants of this happening.
