Just today (it is 87 degrees) I have a severe infestation of red spider mites. I have a long hand laid stone ramp (for my husband's wheelchair) and it is completely covered with them. I just purchased almost $200 worth of annuals and vegetables and set them on this ramp. What in the world can I do? I was told to purchase SEVIN, and I sprayed the ramp with this; but unless it hits each one, it doesn't look like it killed them. I have never had these before. They are crawling up the outside of the stone ramp, etc.

I would recommend spraying the plant with neem oil. We have found it to be very effective against pests and it is safe for humans and pets plus it will not kill beneficial bugs. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
