A base assembly has an upward plate, a downward plate, a side wall, a front, a back, and laterally spaced sides. A drive assembly has drive wheels which extend downwardly from the downward plate and has a caster wheel. The drive assembly also has proximity sensors. A vacuum assembly has a vacuum slit formed in the downward plate between the laterally spaced sides. A source of vacuum pulls a vacuum through the vacuum slit. A tower assembly attracts and kills insects while the base assembly and tower assembly are driven by the drive assembly and the vacuum assembly vacuums up insects.
