I have lived in west texas 18 years of my 44 years on this good earth. I have seen maybe 5 black widows, 3 scorpions,.and 2 rattlesnakes, not counting the thousands of em you see at the rattlesnake roundup in sweetwater every year. Never seen a brown recluse tho i know what to look for. Seen many fire ant mounds, those are just a bit of a pain in the ***. A bit of spectraside fire ant crystals on the nest, and some water to wash it in, and they r done.
Theres crazy stuff every where you live. When i go to the junkyard i tap on the car bumpers with a socket wrench to let snakes know im here, it lets them get away. Rattlers are more scared of you than you are of them, they will strike whrn threatened, or cornered. They prefer to flee and not be around people. The rattle on their tails evolved from grazing animals accidentally stepping on them, its their warning to keep away because they feel threatened.
Spiders, and scorpions just squash em with your boot. I live in town, my home was built in 1979. Since its not on the outskirts of town, i have never seen any of these critters except for fire.ants which i got rid of pretty quickly.
The other critters you will see in the country.
Good luck, i love it out here, maybe your relatives are scaring you so you stay put and dont move LOL
