I sprayed the deck with Bifen I/T and the springtails were back in a day. So then I sprayed with Taurus SC and the same thing. Would putting these granules between the deck boards onto the dirt below help? There isn't any access from the side of the deck, it's been closed off with wood siding to keep the chipmunks, etc. out. There is a 5' wide concrete walkway around 2 sides of the deck. The other 2 sides of the deck are against the house. What can I spray to keep them off the top of the rails and ceiling on the deck floor?
Demand G Granules can be applied to the lawn as directed. Bifen IT can be applied around the structure including windows, door frames, cracks, and crevices. We would recommend exclusion and reduction of moisture/water on the property. They are attracted to moisture/water sources. Here is a great article on springtails. The products just help with relief but it is essential to address the moisture in and around the structure. If they are under the deck, you will want to inspect and address that space.
