Will these foggers kill or scare my bees away? I don't wanna lose my pollinators.

The short answer is yes. The long answer is also yes.

They also kill other beneficial insects that make a living off eating mosquitoes and mosquito larvae.

ETA: It is more harmful to native bees than the western honey bee. Social bees, like the honey bee (and to a lesser degree some social bumble bees) are more insulated to the impacts of pesticides just by the nature of their social existence. They can buffer the effects by somewhat isolating the pesticide to different parts of the hive.

With native bees, such as leaf cutter bees and ground bees, they don't have such a buffer. They're solitary and take the full brunt. Leaf cutter bees are especially susceptible because they directly handle and incorporate foliage with residual spray into their nests, killing not just themselves, but their offspring.

The issue is compounded by the fact that many pest control companies spray during the most active hours for native pollinators.
