They generally don't re nest at all because they die. The fertilized queen hibernates and starts all over again in the spring. The rest die.
If you can kill them that is even better though as they prey on our native bees which we already have a major shortage of.
They also won't nest near another nest.
You can buy fake nest to hang around your stand for about $10-15 the queen won't start her new nest around what she thinks is an existing nest.
The nest building started in spring though. Now is when they(the nests) start getting big enough to stand out not when she starts building it. So if she is going to build there she is already started.
