How do I know Termidor SC is doing anything ?

As a first time user I just put Termidor SC into an outside wall where I noticed the brown ball like termite crap close to where the wood siding butted up against the concrete. While it foamed etc., it dried up clear in about 30 minutes. Am I supposed to be able to see any residue after the foam has disappeared and how do I know it is doing anything?


Termidor does not leave a residue and so what you saw was normal.  Unfortunately there is no real sign that you will see to know that it is working other than the fact that you will not have any new termite activity.  If you treated correctly and the termites did come into contact with the Termidor SC, then it will work.  You have to trust that Termidor is the best termite control product for a reason.  Since it does not kill the termites right away and it allows them to take the product back under the slab where the rest of the termites are, it takes up to 90 days to kill all of the termites.  So you should not disturb the area or check to see if there is still activity until after 90 days.
