Nick,
Are you aware that the link for this ppt does not work?
Russ Ackerman
The link is still not working.
I recommend a professional IT guru to evaluate and correct the link to "See the chronological spread of Formosan termites (ppt)".
before closing.
I found a great powerpoint presentation on termites if anyone is interested.
