Letinchubo letintsatfu letingenhla tivame kusetjentiswa ekukhiciteni i-formic acid. Njengentfo lebalulekile yemakhemikhali laphilako, i-formic acid isetjentiswa kakhulu etimbonini letifana netindvwangu, sikhumba, kanye nerabha. Ngako-ke, intfutfuko kanye nekusebenta kahle kutebucwepheshe bekukhicita kubalulekile ekwenteni ncono kusebenta kahle kanye nelizinga. Esikhatsini lesitako, ngekutfutfuka kwetebucwepheshe lokuchubekako, tinchubo tekukhicita i-formic acid titawuchubeka tigucuke, kwenta kutsi kube nekukhicita lokusebenta kahle futsi lokungalimati imvelo.

Kute utfole intsengo leyehlisiwe ye formic acid kusukela nga August kuya ku October, chafata lapha kute uyitfole.
