QUESTION: Could you identify this insect that is boring through my kitchen drywall?

ANSWER: Billie,

Unfortunately I can't see enough detail in the first image to id. Can you take it out of the bag and re-photograph? The hole in the drywall could be an emergence hole from a powderpost beetle. Do you know when the wall was constructed? Have you noticed more than one of these holes? Post a follow up and I'll try to help figure this out.

QUESTION: Jack, sorry for the delay I had to "catch" another one. My home was built in 1980. This is the only hole I can find at this time but 2 years ago there were 2 other holes about 6 inches directly left of this hole. I sprayed w/Home Defense and thought it was a done deal. Guess not. Hope these pics are better.
Thanks,
Billie

ANSWER: This is a termite. Have you noticed any course, gritty material below the emergence holes? It is probably either a drywood termite or the subterranean termite and the control methods are different depending on which one you have. Where is the house located? Take a look at this page http://www.livingwithbugs.com/drywood_termite.html are you located in the red zone on the map? Also, is this wall on the first floor above a crawlspace? Is it an exterior or interior wall?

QUESTION: I live in central Indiana. My home has a crawl space and this is the southeast exterior wall. Single floor home.

Answer
Ok, these are probably subterranean termites (see http://www.livingwithbugs.com/termite.html for a bit more about these particular termites). The colony likely stated in the soil on the inside of the foundation under this wall and has extended upwards into the wall around the sill plate. If you go into the crawlspace you may be able to see the shelter tubes from the soil up into the walls. You can treat the soil and use the new baits (see http://www.livingwithbugs.com/termit_2.html). It can be a big job especially the soil treatment so you may want to engage a pest control company to help. Post a follow up if you have questions as your plan develops.
