Schools consist of environments that offer favorable conditions for nesting by
ants. This study aims to identify the factors associated with the occurrence
of ants in four environments at schools located in urban areas. Sampling
was conducted in kitchens, warehouses, dining rooms, and outdoor areas
in twelve schools in four cites in the western region of the State of Santa
Catarina, Brazil. For sampling, baits and manual collection were used.
The environmental variables were obtained in each environment. Similarity
between schools regarding ant composition and abundance was assessed
by a Non-metric Multidimensional Scaling. We sampled 1,478 specimens
of ants and identified 45 species. Similarities (60%) were observed in the
abundance and composition of ant assemblages among schools in small
towns (Caxambu do Sul, Guatambu, and Palmitos).The presence of outdoor
areas with vegetation and green areas in the surroundings, size of constructed
area, and frequency of insect control event contribute to the abundance
of these insects in the schools environments. Ants are not recognized as
potential vectors of pathogenic microorganisms in schools and are neglected
if considered the periodicity of insect control.
