I don't know. So wear long sleeves buttoned and use gloves and wear long pants and boots over the end of the trousers at the bottom of your legs.
Not sure. If you have work to do just wear gloves and use a leaf blower to clear away and stragglers.
Because spiders do hide in protected areas, and could be out of the cold, I am not sure that they hibernate. My suggestion is, wear protective clothing to be safe. But a brown recluse spider is just as problematic as a black widow. So just stay away from all spiders. Brown recluse spiders are small. love hanging out in rocky walls etc, and look very non-threatening, but can cause a lot of damage.
google...you may get correct information that way.
Strangely enough the male spider dies not long after mating the female spider has her sack of babies and dies of starvation protecting them So they are all dead during winter apart from the eggs which hatch out in the spring.
My garden has no visible spiders where they were, this is the right time for them to go.
I am in the UK and talking about mostly the common European Spider. Be careful or google the life span of a black widow.
I don't know but I mis mine:-( not seen him for weeks..:
