Frequently Asked Questions

How do I know which kind of ant I have?
Size, color and behavior narrow it down quickly for most Hammond homeowners: tiny brown ants that smell like rotten coconut when crushed are odorous house ants. Large black ants at night suggest carpenter ants. Small dark ants trailing from sidewalk cracks around Hammond are usually pavement ants, and a pro can confirm with a hand lens.
How long does professional ant treatment take to work?
Baits are slow on purpose. Foragers need to survive long enough to share the dose with the queen, so a Hammond pro will tell you to expect one to three weeks. Perimeter treatments build over a similar window as exposed ants spread the product through the colony in Hammond.
Why do ants keep coming back after I spray?
Because the nest is somewhere you did not spray. Most colonies around Hammond sit in soil, slab cracks or wall voids, sending workers along the same scent trail every day. Until the queen is reached with slow-acting bait, ants in Hammond will keep using that route.
How do ants get into a house?
Ants need an opening thinner than a credit card. Around Hammond homes that means expansion joints, window frames, utility penetrations and the gap where siding meets the slab. A Hammond inspection maps these so sealing goes where it counts.
Is a quarterly ant control plan worth it?
Quarterly plans in Hammond typically cost more per year but less per visit, and they include the exterior treatment that stops trails at the wall. The value comes from consistency. Homeowners in Hammond with a history of repeat problems usually get the most from them.
Should I be worried about ants in my house?
For Hammond homes, ants live in colonies, so the fix is reaching the nest rather than just the ants you see. For Hammond homes, identify the species, follow the trail, and use bait or a targeted treatment, then seal the entry points and remove the food source.
Do most people try DIY pest control before hiring a professional?
For Hammond homes, store sprays kill the ants you see but rarely the colony, so DIY results are usually temporary. For Hammond homes, bait is the more effective DIY option because workers carry it back to the nest, but persistent or structural ant problems are usually worth a professional.
