You may see more bugs after your first treatment. Specifically, if your home or business hasn't regularly received preventative treatments, you may see more pests being flushed out of their habitat. After treatment, the products we use don't kill the pests instantly and it takes a little time to take effect. Bait products, the ones taken back and shared with the colony, may take a few days to a week to work. A good rule of thumb is if you are seeing more than the occasional pest 10 days after a treatment, you may need some intervention from your pest control
company.
