Thank you, Alan! I will evaluate this for use at home, as I luckily don't have ant issues at work. Might not do it as my ants do walk around ALL over my kitchen a LOT and I might have concerns about long-term accumulations if they carry it all over the place over time...
And thank you, Joel, for pointing out the standards compliance bit. We probably don't have that legally enforced in Peru but I will keep it in mind from now on! Thanks everyone for the always useful exchanges on the pest list.
