Well, I have a few things to say about this.
What kind of ants do you think they are? Are they big ants, like carpenter ants? or are they Fire Ants?
The next question I have...what state were these shipped from? Did you buy these from someone who is a licensed inspected nursery, or just a backyard grower selling stuff?
The reason I am asking this is...are you aware that there is a FEDERAL plant quarantine in effect that bans the shipment of plants from certain states because of the possibility that they will carry either the black or the red Imported Fireant unless the seller is a licensed, inspected nursery who has an official certification from his or her state that says they are in compliance with the fire ant quarantine? There are laws that govern this. If this person IS a licensed nursery and has (or does NOT have) an official compliance agreement in place and is shipping infested plants across state lines, they should be reported to the USDA in their state. And if they are NOT a licensed inspected nursery at all, and are shipping infested plants across state lines...they should be reported to the USDA in their state.
This is how invasive and exotic pests are spread, and it can be devastating to the ecology of a place to become infested with a pest they did not already have.
I would suggest that you go here:
And review the laws for your state, Kansas, and also the state that these plants were shipped from, and you should call the USDA in the state of origin and ask them to investigate the seller. Tell them what has happened. They will look this person up on the list of registered plant nurseries that all states keep and be able to know #1 if they are a real nursery and #2 what compliance agreements they have in place with their license. If they are not registered as a real nursery, they will take action to either get them licensed, or stop them from selling. If they ARE a registered nursery, and are shipping ant infested plants across state lines, they will help them come into compliance.
Please do not ignore this issue. Its important that this person is stopped from doing this again. There are strict laws against this because of the damage that invasive pests like this can do to agriculture and to ecosystems. And with climate change, these pests are able to survive in places now that they could not before.
