I writng in hopes you can help me on what we were told is weevil (s) in the wood of our 5th wheel dining table, chairs and cupboard doors. Theres tiny holes in straight lines and they leave sawdust piles. We've had our 5th wheel 4 years now and this is the first time we've seen this. There isn't any food in the 5th wheel to attract any bugs. We're very concerned as our 5th wheel has alot of wood in it. What kind of weevil is this?
What can we do? Any help would be appreciated.
It sounds like you have WOOD BORING WEEVILS. The adults are reddish brown to black and look a lot like common weevils found in the pantry. The big difference is that Wood Weevils cause damage to wood much like POWDER POST BEETLES. Wood Weevils will infest wood "post construction" meaning after something has been built or installed. This can happen anytime so 1, 5 or 10 years after you've owned something they can appear. The only thing that makes me wonder if you definitely have them or not would be that wood weevils like to target wood which is moist or damp. Furniture like your 5th wheel is usually kept dry so I'm not sure 100% that this is what you have. But knowing the exact species involved here probably isn't too important…
Powder Post Beetles are more likely to be infested in wood that is used for construction of homes and furniture. Their larvae eat wood so hatching eggs are what will be causing the damage. Sometimes this damage won't be seen for many years after a piece is brought in so again, what you're seeing would be perfectly normal even though you have owned it for 4 years. Powder Post beetles like dry wood and many times you never see anything except the exit holes as explained in our POWDERPOST BEETLE CONTROL ARTICLE.
If you would like to control this pest, you'll need to treat with either the BORACARE or the JECTA GEL that we mention under the FURNITURE WEEVIL TREATMENT section of our powderpost beetle control article. Any of the wood boring weevils, beetles or borers can be controlled with the products featured on our site.
