If a queen dies can workers really turn a fertilized normal egg to a queen's egg

My last hive died off two months ago, I was waiting until cooler weather to break it down for the season, and when I drove by it today--a free swarm of bees moved in!

Now, this weekend, all I am going to do is a bit of weeding next to the hive!

Zone 8a, Eastern NC

Connecticut USA. Cool weather means it’s time to put on our mouse guards. But why don’t bees sting to death any mouse who dares enter the hive? It’s bizarre. EDIT: Thanks to everyone who pointed out that it is when bees are in cluster due to cold that mice do their damage.

Hello! Midwest USA. A local farmer and apiary in the area offers a lot of free honey if their apiary co-op can use your land for some of their hives.

My question is we have 10 acres that we live on and would put the boxes on the back 5 acres. Would my kiddos, husband, and I need to avoid using that area for playing, 4 wheeling, etc at risk of being stung and or disrupting the hives?

I love bees but I also wouldn’t want to lose a portion of my land to those fuzzy friends

Thank you!

Just curious.
