Hello, I have some furniture that had wood worms. They are leaving holes. I live in a warm environment. The furniture is a log bed that has polyurethane on it is there any way to save the bed and the other furniture in my home. I am moving soon and need to treat ASAP. What should I use?
If you read through our POWDERPOST BEETLE CONTROL ARTICLE, you'll learn that what's happening is pupae which are hatching out in the logs are now tunneling out as adults. The pupae are the third stage of this pest and it's this stage where they "morph" from larvae to adults. You can't kill them in this stage and until they all release, you should expect to see new holes. This will happen whether you treat or not.
Now if you do treat, any larvae still in the wood feeding would ingest the treatment and die. In the end this is what you need done to stop the cycle.
Unfortunately there is no way to tell just how extensive the infestation might be and how many larvae might still be active. Is it likely there are more in the wood? Probably. Is there a way to treat the wood to prevent further damage? Yes. The two product options would be BORACARE and JECTA GEL.
The Boracare can only be used if you strip the Polyurethane off the logs or if the wood has enough unfinished sides exposed to allow the Boracare to penetrate. And since you didn't mention how thick the wood is, I'm not able to judge if you definitely need access to all sides of the wood or if one side being treated would be enough. In general you shouldn't expect to get more than 4 inches of penetration from the treatment so if the logs are 8" or more thick, you really need full access to get good penetration with the Boracare.
Alternatively the Jecta Gel could be used. By drilling access holes in discreet locations, you could inject enough of the jel into the wood to get good penetration. This would save the time and effort needed to strip the wood of it's urethane and could be a viable option. In the end, the Jecta Gel would do just as good of a job and for cosmetic reasons is sometimes a good way to treat.
