  • Hello Jessica,

    Vanillin is one of the ingredients in Bye Bye Insect that causes the yellowing on light colored animals.

    This will not hurt your animals and will wear of in time after stopping the use of the spray.

    On the directions it says it may cause a slight yellowing on white or gray hair.

    Please call 1.888.562.4241 if we can be of further assistance.

    Thank you,
