1. How long have you noticed the problem?
A long history of activity indicates a colony
located in the structure. In northern regions, activity indoors during colder weather is strong
evidence that a colony is located in the structure.
2. How many Ants do you see?
Seeing many Ants frequently indicates an indoor
colony. If you see them only occasionally, they may be random foragers coming in from the outside.
3. Where are Carpenter Ants seen most often?
This will provide a clue to where Carpenter Ants are foraging and nesting.
4. Have you seen any small piles that look like
Frass piles are usually located close to nest
5. Have you had any water leaks or noticed any rotting
wood? If so where?
Carpenter Ants often nest in moist environments like damp or rotting
wood. You should inspect these areas first.
6. Conduct inspections in the evening or early morning.
Carpenter Ants are more active at night, so you're
more likely to observe foraging activity and find the nest.
7. Inspect "lines".
Foraging Ants like to travel on fence lines,
phone lines, roof lines, railings,
as well as driveway and sidewalk borders and edges.
8. Knock on wood near suspected nest sites.
Look and listen for activity. Carpenter Ants sound like crinkling cellophane.
9. Check frass piles for materials such as wood,
insulating, plastic, etc.
Frass material will help indicate specific nest
10. Look for plastic vapor barriers under mulch
Ants trail or nest under the plastic film.
11. Follow foraging Ants carrying the food particles.
They're heading back to the nest. Place food on the Ant trail, then follow them back to their nests.
12. Be mindful of weather conditions during the
Carpenter Ants rarely forage if temperatures are below 55°F.
13. Inspect trees and dead wood.
Carpenter Ants tend to nest in tree holes and dead wood
on the ground.
14. Inspect outdoor plants for Aphids.
Carpenter Ants like to feed on honeydew.
15. Look for tree branches, shrubs, and vines growing against buildings.
Branches and vines provide easy access.
