Didn't notice anything about temperature requirements; tried to spray with water hose in 50 - 60 degree weather. Repellent must have been to cold to disperse. I'll have to bear with the mole 'til spring and try again.
Not sure how to rate this... I used this product last year and the moles were gone yippie.... i'm getting the moles back from my neighbors yard just a little tiny start no big deal..... We ordered a month ago and used the product like before.. omg the moles started coming back like crazy. Not sure why it worked great last year and not this year... So I guess you are on your own unless I can figure why they came back this year with the mole control on my yard
