Default Fire ant repellent check it out.


In a paper published in the journal Applied Entomology and Zoology, a group of researchers led by the myrmecologist Yoshiaki Hashimoto, who teaches at the University of Hyogo in Kobe, Japan, found that lacing ant traps with a microencapsulated form of allyl isothiocyanate (AITC), an organic compound that causes the pungency in wasabi, horseradish, and mustard, kept fire ants away. Microencapsulation (read: making tiny capsules) preserves the AITC within a protective shell. Ants that came into contact with the AITC eventually died.
The results proved conclusively that fire ants fear wasabi. Only the trap with the regular plastic film caught ants. The one with the AITC film repelled the ants—the researchers recorded a video of ants getting to the top of the bait tube and recoiling from the tiny hole marking the point of entry. In the final instance, ants placed inside the small tube containing AITC film died within 40 minutes of exposure.
The use of wasabi-infused plastic film to repel invading fire ants offers a sharp new research direction for the disparate fields of food science and entomology.

I avoid the stuff, too...but, honestly, I've never tried it. not into hot and spicy.

nice to see something like this can work.
