Carpenter ants in a window sill

Carpenter ants in a window sill is very common.  In fact, carpenter ants themselves are so common that it’s the number one pest that we treat for from April-July.

Most callers that call our company don’t know exactly where the ants are coming from, but those that do may see a few common signs.  One of those signs would be frass.  Frass is the garbage that is kicked out of a carpenter ant colony.  It contains sawdust and bits and pieces of other insects.  When an exterminator thinks there may be carpenter ants in a window sill the presence of frass is a dead give away they’re correct.

Signs of carpenter ants

Exterminators, no matter how good can’t see through walls any better than anyone else.  There are tools that can help, but nothing exists that can show exactly where a nest is at every service.  This is what makes carpenter ant work so difficult.  Some of the things that will help locate a nest include:

  1. Following ants while they forage
  2. Locating water damaged areas
  3. Finding frass

Where do carpenter ants nest?

A favorite area for carpenter ants to build nests in is window frames.  They’re particularly fond of older windows because water eventually gets in and creates water damage.  When they set up a colony in a water damaged area it can be on any one of the four sides.

If you’re unfortunate enough to have this situation I hope you’re fortunate enough to have frass. If it’s present a company like Envirocare Pest Control will know exactly what to do to solve the problem.

How to get rid of carpenter ants in a window sill

A good exterminator will spend 80% of their time inspecting and 20% treating.  Once found in a window frame a small amount of insecticidal dust can be injected into the nest via a crack or crevice or through a small drilled hole.

If done properly this method will rid your home of ants.

Now what about keeping them away for good?  Envirocare Pest Control can help with that.  Call 1-888-879-6481.
