Ant Extermination in Kitchener: FAQs
Common questions about ant extermination for Kitchener homes and businesses.
Why shouldn't I spray ants myself?
Store sprays scatter the colony and can make it split. We bait so workers carry product back to the queen.
Do you treat carpenter ants?
Yes. These damage wood, so we locate the nest and treat the galleries directly.
How long until the ants are gone?
Baiting usually clears a colony within a couple of weeks; large carpenter-ant nests may need a follow-up.
