I've had to learn some things.

Some specificity concerning Louisiana:

They can fly.

I've hit them with a cypermethrin (a synthetic pyrethroid) spray (Cyper WP).
They don't fly with that from an outside wall.
They drop. Then get squashed.

Cypermethrin has its own, "problems."

In addition to hand pump sprayers I have a large tank sprayer that hooks up to the battery of my riding lawnmower.
A bug man comes once a year to spray underneath the house (I'm too old to get under there myself anymore). I hit the lattice, porches (including underneath and roofs), sheds, well pump house, the bases of some trees near the home once a year myself.

It is essential to have a perimeter spray inside the house as well.

As implied, cypermethrin has its own evils.
It is a toss up... evils of the chemical vs evils of various bugs.... termites, including the Formosans which will eat your house if you let them, American cockroaches, which live outside and will live and reproduce in your house if you let them, centipedes... which will nail you if you let them in and step on one in a night-time bathroom trip... and the subject of this thread.
Then there are the brown recluse spiders... Louisiana has been called brown recluse heaven...
An inside perimeter spray is less effective with those because their thoraxes are generally above the barrier as they move... but it still helps... been nailed by them 4 times.
I'm one of the few who don't get the nasty necro tissue effect... no, it is to the central nervous system for me.... with some quite, "novel," effects.

I live in what amounts to a U.S. Jungle.
Bayou country.
You can clear around your home but you are still, "in it."

"Emerging," is a hoot. "New," is a hoot.
It's always been here in terms of a single human life span presently breathing and still alive.
What is, "emerging," and, "new," is Awareness... and Testing, both of which are in relative infancy, but baby steps are better than no steps at all. Tweet
