Q.will Raid ant killer harm later planted basil?
In cleaning out a very large container I discovered it was infested with ants. Subsequently I sprayed Raid ant killer on the soil, which filled about 2/3 of the container. I did this twice mixing the soil between sprays. I then filled the pot with new soil and planted basil. Will the Raid cause a problem with the consumption of the basil in the future. Thank you for your assistance.

Absolutely... DO NOT CONSUME THIS. Plants will take many things into the roots, which will lead to consuming this if you have had any at all come in contact with the roots. It sounds like there is quite a bit in there. This will likely be fatal to you or anyone else that consumes this plant.
In the future, only use something on the plants that you would feel safe consuming, as it will likely be inside the plant as well as on the outside.
Neem oil, rosemary oil, garlic extract and pepper extracts are all very safe ant deterrents.
