If that does not work you can step up to Bayer Temprid. It even kills bedbugs. Residual lasts for 6 months.
Now, treating the bites? I've been bitten by Brown Recluse spiders 2 times. Simplest treatment is cut down a nitro patch the size of the bite area and leave it for a couple of days. It will dilate the blood vessels and allow the body to clean up the venom. Everyone who tried this has succeeded in clearing up the bite.
I have even used 1/4 of a nitro tablet on top of bite, one drop of water to dissolve, covered with band-aid for a couple of days. Always works.
There was a doctor in Ft. Worth that regularly treated his patients with this.
You’ve been bitten by a Brown Recluse twice??
Move to the Dakotas or Minnesota where it's too cold for them.
Was supposed to be just a label change to allow for outdoor use so Bayer could sell more product.
When Temprid FX came out, it like a light switch was turned off…no targeted kills and especially no collateral kills of non targeted pest.
Best guess was that Bayer out sourced to China for money saving and onto Just In Time shipping which bypassed quality control inspection prior to finale manufacture.
The Bayer rep seemed scared for his job in offering different lot number replacement.
Temprid FX was abandoned by my former employer. The Texas Regional boss told me…”We don’t talk about that”.
