We discovered a white grub (1″ long or so) living inside a wooden picture frame. we first noticed some tiny holes that powdery stuff came out of. we’ve had the frame for 6 years. painted surface. is it the only one that might have been in the frame when we got it? More? Help! thanks.
No doubt you have some kind of wood beetle living in the frame. Unfortunately there is no way for us (or anyone for that matter) to tell if this is a new problem or one that has been going on for some time. Nor are we able to tell if it’s an isolated case. In most situations, if you see one there are more and a treatment is warranted. There is just no practical or efficient way to “test” or inspect wood so the industry has learned to handle it as “active” when at least one is found. From there, the logic is easy. Following the treatment, the problem will be solved with certainty.
In this case, if you want to keep the frame, you have two choices. The first is to do nothing and hope the situation “dies out” and the beetles don’t spread to other parts of the home. This would be a poor choice.
The second option is to treat with JECTA GEL. This would be a fairly easy project. Basically the back side of the frame would require small holes drilled into which the gel would be applied. After allowing it and allowing the gel to soak in over a week or two time period, the treatment would permeate throughout thus killing any feeding beetle larvae and breaking the cycle. Within 1 month the holes could be sealed back up and you could keep the frame without further worry.
Of course, the frame may have no value to you at this time and discarding it from the home would also take care of the problem. Here are direct links to the information and products listed above:
