Title: Toxicity of catalpa wood?
Answered by: Guy Thompson

QUESTION:

Is the sawdust from cutting up a catalpa tree or the smoke from burning the wood toxic? Thank you,

ANSWER:

I have found a number of Internet sources that discuss the possibility of toxicity of Catalpa speciosa (Northern catalpa), but there seems to be little evidence to support the allegation.  The US Dept. of Agriculture web site does not mention toxicity as a problem.  But to be on the safe side, it might be advisable to wear a mask when Catalpa wood dust or fragments are in the air.
