....snakes aren't much of a problem either....we use to have a few as pets years ago....we will find and try most any and everything to fight the dang ants and stick with what works the best....I know we can't take em all out, but sure need to control their numbers and keep them from gaining ground....gotta thin some trees out and get more sun to the soil....lessen the leaf litter, nuts, and dead wood....get grass to growing....
YIKES!!! I jumped back and screamed. Then I did a karate kick and the tarantula was no more. 
I’m told their bite is not much worse than a bee sting, but the way I see it, why take the chance of getting bit, when you don’t have to. 
For the fire ants....wal mart, home depot and lowes sell BAYER fire ant killer, only get the powder and just use a little on the mound...if you start from the center of your property and work them outwards toward neighbors...they move away....that is soooo much better than anything else i have tried...We had them back on the farm too....so many trees, shade, moisture, and food for them....we had orb, wolf, recluse, widows, and jumping spiders everywhere....they don't bother us very much....most are beneficial, so tolerated uless they infringe on our areas....then they are dealt with....
I would of had heart failure !In Lake Worth we also had brown tarantulas. They were realy hairy and about 1-1/2 to 2” across. They had 1/2” holes in the ground, that they would cover with somme of their belly hairs.
One day I was on the back porch (about 7’ above ground level) and was planning to go into the back door, into the master bedroom. We usually kept that door shut/locked. As I reached for the door handle, I saw something, didn’t really look at the handle, but then saw something that almost matched the trim in color. So I looked closer and it was a tarantula, just ready to climb onto the door knob.
Then I did a karate kick and the tarantula was no more.
Not just a kick, a karate kick! 
Good thing you don't live in Florida then .... oh waitWait till the wolf spiders drop down their webs from the trees at night...and the bananna spiders OMG....i can deal with the snakes...but the spiders
Well, YEAH! It was right at waist level. Just a regular kick wouldn't do! The significant thing about that is that I COULD do a karate kick.
With arthritis in my hips, I can't kick that high anymore. 
While screaming "YA!"
Good thing you don't live in Florida then .... oh wait
I've only seen wolf spiders in the basement of our prior house. Didn't know they had webs up in trees.
