Spider Beetle

Home Pest Problems

Spider beetles are pests of stored products such as grain, cereals, flour etc. They often bore holes in packaging in a similar way that borer bore holes in timber.

Identify the problem
Spider beetles are a group of insects that are pests of stored products. They include Australian Spider Beetle and Golden Spider Beetle. They will borer through packaging to feed on and infest grains, cereals, flour, pasta and other starchy food in kitchens, larders, shops, warehouses and mills.
How to solve the problem
1. Try and identify possible sources of the infestation. Check your kitchen, pantry and nooks and crannies around the house and not just where you have seen spider beetle.
2. If you have found spider beetle infesting your pantry or kitchen cupboards it may be necessary to check for and discard all contaminated products. Then remove all food stuffs and lightly spray the empty pantry or cupboards with NO Bugs Indoor or NO Bugs Super. Leave the cupboard empty for at least 24 hours then wipe down, leave to dry and replace your food stuffs.
3. Spray all the cracks and crevices around your home with NO Bugs Indoor or NO Bugs Super.
  NO Bugs Super Bug Bombs or NO Bugs Super Fumigator will knock down a lot of the insects and can help to penetrate into the nooks and crannies. However the concentration in the treated rooms needs to be maintained at a high level for an extended period to penetrate well, and the source may not be in the treated room/s.
