You did not mention what Sevin product you are referring to but the Sevin Concentrate product must make direct contact on the fleas for product to be effective per the product label so you would be making applications anytime fleas are present outdoors. If you are looking to treat inside and outside for fleas, you should definitely get our Indoor/Outdoor Flea Kit. It comes with an excellent product called Onslaught, which is great for both outdoors and indoors. It is also very safe around pets and has a long residual. Also in the kit is an IGR called Martins IGR. It is photo-stable up to 14 days which is about as long as you will find for an IGR that will be outside. Of course you should mix both together in the same tank and apply at the same time both outside and inside. You must vacuum indoors prior to the first treatment and then vacuum daily for 14 days to help eliminate some of the flea eggs and flea debris that the pupae feed on. Outdoors you should concentrate on moist, shady areas and areas where the animals spend time resting. After 14 days a retreatment may be needed to eliminate any left over fleas (the kit comes with enough product for repeat applications).
