We moved into a home in Ohio about 2 years ago and would see an occasional carpenter ant. This winter, December, we started finding lots of them inside and called an exterminator - very nice guy- explained that these are VERY hard to get rid of without finding nest, etc. After several days of observation we located the colony, within the trim void of our master closet in our bathroom - he came out the same day we found colony and said he could spray it or use our shop vac - I opted for him to spray for immediate action. After reading your website, I now realize that wasn't necessary. No problems at all until now, May! We did have exterminating company come out right before we started seeing them again to spray the exterior house/landscaping so we believe this "drove" the ants inward, maybe sensing the repellant outside? Probably another bad move! Started seeing quite a few showing up in our master bedroom, rechecked closet voids and none are there. After removing some drywall and finding all kinds of "sawdust" and much more observation, located them to the inside of the windowsill, found a colony that had made LOT of grooves/ridges throughout it and sucked most of them out and saw no ant activity at all until the next evening - about 12 hours later - now we are finding 6-10 ants/day in the same location as that window. We did use Home Defense so they seem to die eventually but trying to figure out if we may have ANOTHER colony or if these are stragglers trying to find their home? Help -do we remove more drywall - will they eventually stop coming around? Also, what should be our game plan now that we have sprayed out and in? Will the ants eventually die off? Will they continue trying to come in? Should we abort all exterior treatment except granules around foundation? We just had new siding put on and now we are worried that they are between the insulation board and the old siding before - they just went over that old siding. Don't know if we should have someone come out and remove some of siding and pull up old siding where problems are - please help! Thanks so much!
