Dear Cecil:
Our mother is moving to a new apartment and has really nice furniture. Unfortunately, the apartment she is living in now has roaches! Not wanting to bring the buggers along, we are trying to find ways to kill/prevent them from bumming a ride to the new residence. I went on the internet to ask about “bug bombs” effects on furniture (wood and fabrics). The answer was this: It will damage things if not cleaned off (therefore useless on fabric and wood). Also, bug bombs are best on flying insects, and not on roaches, etc. It advised to use boric acid (borax) instead. I thought I would pass this info along. Thanks for listening.
Mimi
P.S. Keep up the good work!
