how can i get rid of termites biologically in my garden?

there are new chemicals that work, i had termites and can say they are tough to kill since chlorodane is no longer available. There is a new product "termidor" it works differently in very low dosage that the termites dont detect it and spread it through the colony it is slow acting but within 90 days it will kill the whole colony www.epestsupply.com

An arborist would be the best person to ask. Generally when termites attack a tree it is in decline. Termites dont usually eat live wood , so there must be some dead areas of the tree attracting them. They are a natural part of the decomposition process in nature. They eat dead wood and turn it into nutrient rich soil for other plants to grow.

It may be possible to save the trees but only an arborist would be able to diagnose a problem and come up with a solution.

Food for thought - Be thankfull they are eating trees and not your home. You might want to get a termite inspection from a qualified exterminator just to be sure.

Try beneficial nematodes. I'm trying it @ my house for the first time this year. Hard to tell, but I think there are less fleas and other insects.

Spray tree with vinegar. I tried it with ants it works!
