Ants vs Cockroaches

• Ants– Queen– Males– Workers– Larvae

• Cockroaches– Females– Males– Nymphs

Page 3: Ant Food Preferences: The Key to Solving Difficult Problems Philip G. Koehler Margie and Dempsey Sapp Endowed Professor of Urban Entomology University

This is a Queen!!!

And This is a Winged Queen.

Concepts of Baiting• Placement so that ants find them

• Particles small enough for small ants

• Foods that ants prefer

• Slow acting poisons to allow trophallaxis (regurgitation and feeding others)

Food Preference

• Sweet feeders -- climb shrubs and trees for honeydew• Protein feeders -- on porches and window ledges feeding

on dead insects attracted to lights• Lipid (oil) feeders -- in lawns feeding on seeds • Do not consume wood

Page 11: Ant Food Preferences: The Key to Solving Difficult Problems Philip G. Koehler Margie and Dempsey Sapp Endowed Professor of Urban Entomology University

Bait by Ant Food Preference

• Sweet feeders— baits for these ants contain sugars or syrups

• Protein feeders— made of ground silkworm pupae

• Lipid feeders— usually contain peanut butter or soybean oil
