I know this is an old post but i did want to comment. The U.S. environmental
protection agency requires that registered soil termiticides remain active for
5 years. Per the chemical manufacturer the chemical is good for 5 years
because thats what the federal government requires. With that being said what
happens is after about 4 years and 9 months the chemical begins to break down
due to a number of things like soil erosion, rain, heat, evaporation, just to
name a few. Keep in mind 5 years for a pesticide to stay active is quite
impressive considering non termiticides typically only remain active for about
30 days. Once the termiticide becomes inactive the termite colony is no longer
kept at bay in the soil and they will begin feeding on cellulose once again.
Termites are blind and once they begin to feed on the cellulose of your homes
wood/drywall foundation they risk popping through and forming what all home
owners dread to see which is the mud tubes. They dont mean to, in fact if they
werent blind termites would prefer not to be seen. Booster treatments aren't
do or die but with an investment as large and sacred as your home it is
definitely recommended. They go in pop open the plugs from the original drill
holes and reapply the termiticide. Termiticide is a time release chemical
which the termites eat and bring back to their colony which kills them from
the source thus keeping them at bay in the soil below your house for another 5
years.
