Ticks are probably the one critter I have not found the perfect solution to. DE can be spread on the soil and grass but this takes a while to make the cuts in their joints and ticks seem to still get around.
Soapy water mixed with alcohol will knock them down when it hits them, but you still have to see them and that is difficult at best.
What I do now is spray my Alcohol
soap mix into the
trees and on the tree trunks in areas I am going to be working in (this stuff goes away in the first rain after application).
The soap I use is biodegradable dawn (the original formula not any of the "new Improved" formulas), the alcohol starts life as 95% corn whisky.
If you have fire
ants, dissolve a cup of Borax laundry soap powder into one gallon of water then dilute that to five gallons and pour into and all around a fire ant mound. This is the same solution I use to treat
wood that will be in contact with the ground but in that situation I soak the wood and let it dry.
If you have a planted wood pole, you can pour a solution of one cup borax powder to two gallons water all around the pole and you won't have carpenter ants or termites bother it.
One thing to remember about borax, it is a boron compound so you will be raising the boron content of the soil treated and that is an antifungal so it's best not to use it anywhere you want fungi to thrive.
