How Soon After Using Bacillus Thuringiensis To Kill Insects Can Herbs Be Harvested

Question From: R. Perlotto - Miami, Florida, United States
Q: I am an amateur gardener with multiple herbs/spices grown in pots outdoors. I have a problem with insects eating and leaving many small holes in the leaves. If I use BT to counter them, is there any danger to human consumption of the herbs? How soon after use of BT can I harvest and consumer the herbs? Any other recommendations and/or cautions? Thanks.

A: BT is safe for use in edibles up to day of harvest Rick. Best And Happy Yardening, Nancy
