Search through your cupboards, food storage areas such as your pantry or garage. Things to keep an eye out for are: insect, rodent or other animal feces that could be a source of infestation.
If you come across anything that resembles animal feces, these must be discarded straight away. Make sure you’re wearing gloves before touching any animal feces. Remove any trash or food sources that may attract or be exposed to by the spider beetles.
If you find any areas which are moist specifically near food, focus on cleaning and drying those areas first:
2.Clean & Tidy
Clean shelves, cupboards, kitchen surfaces, pantries, grills and bbqs. Anywhere that might have traces of contaminated food products. Sweep those areas then vacuum all areas which might have traces of an infestation, then wash those areas with soap and water.
We recommend using plastic containers with air-tight seals to store dried food such as cereals, rice, grains, seeds and pasta to help prevent possible infestations.
Rice and seeds that are stored for long peroids of time are the ideal places for spider beetles to breed, so we recommend throwing these away.
