If a drying kiln is not available. I have knocked out wood boring beetles with DDVP strips.
Depending on the size of the piece, wrap it in black plastic contractor and place 1-3 DDVP strips (Nuvan is a popular brand) in the bag with the tree. Seal it well and keep it in a warm room (above 75 degreed F for at least 10 days (again, treatment time and number of strips depends off the size of tree). The strips give off a gas (Dichlorvos) that is a true gas and will penetrate the tree but not the plastic. After treatment time is completed, take the tree outside, and open it while wearing a full face respirator (or a very good KN95 mask) and goggles and open the plastic. Remove the strips and let the piece air put for 1/2 hour. This gas is very toxic and should not be taken lightly. Do not open the plastic indoors. The gas dissipates into the outdoor environment and the red will not have pesticide on the surface once the gas is cleared. This acts as a “mini-fumigation” and works well on smaller pieces. The more strips used and the warmer the storage temperature, the more effective the treatment. > On Mar 21, 2025, at 2:36 PM, Jo O <museumartist...@gmail.com> wrote: > > Bugs do not like heat or freezing cold. > If the piece can be put in a drying kiln would be great.
