Can NBS, when mixed with water, be sprayed on the exterior of the house? Wood siding. Is this the best ladybug control product? We also have them coming inside the dwelling and hanging out by our large front windows.
For the outside of the house, NBS would be one product that can be mixed and sprayed with water. But as our LADYBUG CONTROL ARTICLE explains, it’s not the strongest. If you have a major problem, we generally recommend going with the CYPERMETHRIN first and once under control, you can change over to the NBS as a maintenance product.
Both of these products can be mixed with water and applied directly to the siding. And though the NBS can be used as a spray, it was originally created with the intent of being used as a paint or stain additive. When used this way, you’ll find the length of residual to be a lot longer.
