I am a super big fan of IVM but in this case may I recommend you look into horse mint. It is an herb, You can buy extract or pills at health food stores. My wife had her pancreas flair up now and then. We had a lady over who is an herbalist/nutritionist. She specializes in teaching how to forage on you own property or area. We have acres and she walked outside, picked some horsemint buds with flowers. Told us to take a few flowering buds and steep in some just boiled water. She has not had any flair ups since. In previous years I had been spraying this as I regarded it as just another weed in my pasture. This year I picked a bunch before I sprayed. Lastly, by steeping for 10 min the tea did not look very strong. We asked the lady and said that was the desired strength and that more was not better. Also, wait more than 24 hours for second dose , if needed, which she said she had never seen anybody need a second dose.
