Is it necessary to treat my home during the winter months?

Absolutely, if you want to stay pest-free. Winter time is when the hidden pests come into
your home for safe harborage. These include: mice, rats (less common), clothes moths,
pantry pests, spiders, and more.

Keeping your barrier maintained during the winter months
also is important to the early hatchlings that will try to migrate into your house.
As long as the barrier is activated, they will be killed while crawling over it.
