Could be a problem. From a web site:

Q Why is Vikane gas deadly to termites but not harmful to pets, plants and humans?

A Your question is not quite correct. Vikane is equally deadly to all of the above. However, pets and humans are not supposed to be inside the house when it is fumigated. Plants that are to be saved should be removed from the house. The fumigators make certain there are no living beings inside the house, then lock it and secure the tarps around the house so that no one or thing can enter before the gas is sent into the house.
