Need to treat garages, and feed boxes on ranch outside.
There are a lot of products that can be used for black widows and other spider species in a lot of areas. Onslaught FastCap would be a great option for use around the home, garages and areas they would typically harbor in around the home. You would not be able to spray it directly in feed boxes but you can spray under and around them. You can use 0.5 - 1 oz per gallon and treat on a monthly to quarterly basis to keep them under control. You can see tips on controlling spiders and where to treat in general by looking at our Spider Control Guide.
