Ichigeki Sacchuu!! Hoihoi-san

In a near-future Japan, a crisis has arisen as household pests have become immune to all forms of insecticides. To combat this issue, a Japanese company has developed Hoi Hoi-san, a small, doll-like robot designed to exterminate insects. Her counterpart, Combat-san, has also been released by a competing company. Despite their intended purpose, Hoi Hoi-san and Combat-san have gained a devoted following due to their adorable appearance. Under the cover of night, in the home of a devoted fan, Hoi Hoi-san and Combat-san search for insects to eliminate, but Combat-san's intentions are not limited to just exterminating pests - she has a rival in mind.
