Barrier Sprays to Control Argentine Ants (Hymenoptera: Formicidae)

Trail Pheromones in Pest Control

“…These chemical sprays provide only partial ant control because they kill or repel foragers but have little impact on the queens (Rust et al, 1996). Foragers constitute only a small fraction of the worker force and are quickly replaced by nest mates that reach maturity during the treatment period.…”

“…Foragers constitute only a small fraction of the worker force and are quickly replaced by nest mates that reach maturity during the treatment period. Additionally, the degradation of these chemicals commonly occurs within 30 days of application, negating any residual effects (Rust et al, 1996) and increasing the need for reapplication. Granular treatments for ant control are commercially available for use in agricultural systems, especially nursery operations (Costa et al, 2001).…”

Liquid baits control Argentine ants sustainably in coastal vineyards

“…In contrast, broad-spectrum insecticide sprays targeted at ants may disrupt integrated pest management (IPM) programs by suppressing populations of beneficial insects. While these sprays may also kill foraging ants, unlike baits they have little effect on ants in nests and so allow for an eventual resurgence of the population (Klotz et al 2002;Rust et al 1996).…”

Efficacy of Bifenthrin Treatment Zones Against Red Imported Fire Ant

“…Insecticidal barriers are commonly used by homeowners and pest management professionals to prevent ants from entering structures. Rust et al (1996) and Klotz et al (2003) investigated the use of insecticide sprays as perimeter treatments for Argentine ants, Linepithema humile (Mayr). Perimeter treatments with granular contact insecticides have not received as much attention.…”

“…A chemical barrier does not have to kill ants to prevent entrance to a structure (Rust et al 1996). Insecticide repellency has traditionally been thought to be a good characteristic of insecticides used for barriers.…”
