how much termidor to use in perimiter with basements and do I drill holes in basement floors also?
I own an older home with a full basement. Termites have destroyed girders and main beams. I have recently replaced the wood and want to treat it with Termidor. How much should I use in how deep of a trench outside? And also, what grid pattern should I use for drilling holes thru concrete floor and how much liquid should I use in each hole? Thank you very much. I have went thru 60 questions/answers, and havent seen this question asked.

Basically, the rate of application outdoors and indoors is the same whether you are trenching and treating soil or you are drilling and treating below the cement floor. That rate of application is 4 gallons per 10 linear feet. Outside this is easy to do, just mix the Termidor in a 5 bucket (mark off the 4 gallon line) and apply the full 4 gallons every 10 feet. Then cover up the trench and go to the next 10 feet. The trench is only about 3-4 inches deep and wide, although the label says 6 inches.
As far as drilling indoors, most of the time, treating the exterior walls and around any supporting beams or piers is all that is necessary. With Termidor, you are not creating a chemical barrier, you are creating treatment zones where the chemical can hopefully contact the termites. This is all that is needed. Once the termites have been infected, they then begin to gradually die as the continually infect each other. This is called a Domino Effect or Transfer Effect.
Drill the holes every 12 - 18 inches - about 6 inches from the wall, in a linear manner, and apply 1.5 gallons of Termidor mix down each hole. No need to drill in a checkerboard manner. The walls and supporting posts are all that are treated. This rate will get you the 4 gallons per 10 linear feet you are trying to achieve. Then take a piece of paper towel or a Super Plug, plug the hole, and then seal with a small amount of cement to create a seal. Basically, drill the hole > sweep up the cement dust > treat with Termidor > plug the hole > seal with cement. That's it!
You can also spray infested wood directly with Termidor. My preference is Bora Care. Bora Care will last for the life of the wood.
Hope this helps.

The old school way of treatment would be to drill the blocks. This makes a mess in some situations as the chemical has no where to go. Treatment inside and outside the blocks usually works, and in some cases, treatment only outdoors and spot treating infestations indoors works. Food for thought.
