Well since I retired from the insect control business - not a problem. I used a bit of Deltamethrin dust to which took care of the problem and hopefully will prevent it from coming back.
One other option is to spray any type of House and Garden insectide in a large plastic bag and then insert your camera and seal the bag for a day. That will fumigate it and kill every thing. But the trick is to prevent them from the get go thus the light coat of dust in a fe key areas. I even treated the bear boxes I use to secure the cameras.

Both camera's I bought from you have been treated as both had ant colonies.
