Alpine Ant and Termite Foam is designed to spot treat active insect infestations, so it does not have a long residual once applied. This product is a non-repellent, however, so it does have some transer effect among insects listed on the product label. You can reapply Alpine Ant and Termite Foam as needed. If you need a longer residual, you could use a product like Fuse Foam or Termidor Foam. These will last about 60-90 days when used in a wall void.
