I am interested in your NBS Insect Repellent. We have sand wasps in our flower beds and want to get rid of them. Will the NBS work if the wasp are already active in the sand? Also, is there any guarantee on this working to make these leave? Thanks, Kris M.
NBS won't help chase them away from established nests. So use the NBS to repel them from landing on plants or your home but once nests are established, dust the nest with DIATOMACEOUS EARTH using a HAND DUSTER. This will either kill them or if they're away from the nest when you treat, they'll move elsewhere once they learn of the treatment.
