Laboratory and field insights into the dynamics and behavior of Argentine ants, Linepithema humile, feeding from hydrogels.

Hydrogels with sucrose concentrations no greater than 30% appear best for liquid uptake by L. humile. Hydrogels not in direct sunlight will have greater attendance by L. humile and, therefore, less attendance by non-target ant species. Shady and humid places may prolong the longevity of hydrogels, which would imply higher intakes. © 2021 Society of Chemical Industry.
