Service with Terminix began in October 2019 primarily for American wood roach infestation along with ants, silverfish and spiders. We are under an annual contract with quarterly service. Due to regular activity, the technician has been to our residence every month since October. As of June 2020, we are still seeing activity of all the aforementioned pests. Not an expert in this area but would have expected to not be experiencing issues after eight months of treatment.
