Here is information from MSU Extension on poison ivy, including chemical and non-chemical control options (click "download"): https://www.canr.msu.edu/news/new-free-poison-ivy-bulletin-available-for-id-control-and-more.

You can look up pesticides by trade name or common name to see their known effects on bees: https://ipm.ucanr.edu/bee-precaution-pesticide-ratings/.

To reduce pesticide harm to bees, you should try to limit the exposure/contact. Do not spray pesticides on places bees visit, such as blossoms and water sources. While the amount of time a pesticide remains active varies by product and chemical, you can apply pesticides in the evening when bees aren't flying as an additional attempt to try to reduce exposure to bees.
