Carpenter ant nest damage

6133   Hi, there,  I saw this under my deck. Did not see the ant, but I am wondering if it sign of white ant?  Thanks a lot. I live in Burnaby, B.C.  Jerry

The holes and course wood fibre (frass) indicate typical damage caused by carpenter ants. See this web page for more information: http://pestcontrolcanada.com/ants/carpenter-ants
