We enforce the regulations in statute through Title 3, Chapter 4 of the Arizona Administrative Code (see current rules(link is external)).

Can I bring my plants to Arizona from another state?

If you are moving to Arizona you may bring your indoor house plants, that are free of insects and in a commercially prepared potting mix, without a certificate from the state ot origin.

All other plants must be accompanied by a Certificate issued by the origin state that attests that the plants are generally free of pests and meet any quarantine entry requirements.

Plants that originate from areas under quarantine for imported fire ants or harmful nematode pests must be received by a nursery, business, or individual that has a valid "Quarantine Holding Area" so that plant material can be inspected if necessary. For a list of locations that have approved holding areas "Click Here".

Otherwise, check the list of licensed pest control companies(link is external) or look for Beekeepers or Bee Removal Services on the internet or in a phone book. Swarming bees or beehives should only be handled by a professional pest exterminator or beekeeper. The Department does not make recommendations for any company.

More information on how to start a nursery can also be found with the Arizona Nursery Association.
