We say crawling insect pests instead of describing minor household pests individually. We group them together and it mostly consists of grain or flour beetles, ants, silverfish, firebrats, centipedes, carpet beetles etc.
We use commercial strength, broad spectrum pesticides that cover most of the household insect pests. We apply an insecticidal spraying throughout the structure inside and if needed outside the structure.
A follow up inspection is done after the spray and sometimes a second spray is needed depending on the severity of the infestation. In case of multiple family units, we recommend an inspection of the units surrounding the infested one and in most cases a preventative spray to these units yields better and long term pest control.
