Vermin-Proofing Your Steel Shed in Australia

Keeping your shed free from pests should be a major consideration when purchasing a new shed or garage. Spending thousands of dollars to protect your household items or farm produce from the weather, only to have them damaged by pests, is a costly mistake that many people make. At True Blue Sheds, we understand the importance of vermin-proofing steel sheds in both rural and residential settings and offer effective solutions to keep pests out.

Why Vermin-Proof Your Shed?

Pests such as rodents, snakes, and birds can cause significant damage and contamination. Mice and rats easily squeeze through gaps between the slab and the ribs in wall cladding, allowing them to chew wiring and damage stored items, creating safety and health risks. Birds nesting in rafters leave droppings and debris, which affects the cleanliness and usability of your shed and can become a significant issue in various Australian locations.

Preventing pest entry from the outset is far easier and cheaper than dealing with infestations later. Proper vermin-proofing ensures your shed remains secure and clean, and your valuable stored items remain safe.

Types of Vermin Proofing

Base Flashing

A common and effective solution is metal base flashing, typically made from Colorbond steel. This flashing is installed at the junction between the shed wall and slab, sealing entry points and providing a strong barrier against pests. It also adds bushfire protection by reducing ember entry points. Corrugated sheeting ribs typically have gaps of 19mm, while 5-rib deep pan trim sheets have gaps of 29mm, both of which allow rodents entry into your shed.

Slab Rebate

Another option is a concrete slab rebate, which involves creating a step in the slab edge where the shed wall cladding sits. This helps block pest entry but requires careful installation to prevent corrosion from the Colorbond coming into direct contact with concrete.

Infill Strips

Infill strips, typically made from PVC or high-density foam, fit snugly into the profiles of the shed’s wall sheeting. They effectively seal gaps and prevent vermin, drafts, and moisture from entering the shed.

Expanding Foam

Expanding foam can effectively seal irregular gaps and holes. However, its softer structure can be chewed through by rodents. Use it as a temporary solution or combine it with stronger barriers for best results.

Aftermarket Vermin Proofing Options

Several aftermarket products are available for retrofitting existing sheds:

  • PVC vermin seals designed to match various wall profiles
  • Metal flashing kits custom-made or pre-cut to standard sizes
  • Foam infill strips and expanding foam for quick fixes
  • Door seals and brush strips to eliminate gaps at entries

These solutions can significantly enhance the vermin resistance of your existing shed with minimal effort.

Deterring and Stopping Birds

Birds roosting in sheds can pose challenges. Effective strategies include:

  • Installing bird netting or chicken wire under the apex and eaves
  • Using bird spikes or deterrent strips on perching surfaces
  • Regularly removing nesting materials to discourage repeat nesting

Combining these approaches typically yields the best results, reducing bird-related mess and damage.

Pest Prevention Around Your Shed

Proper site preparation and maintenance around your shed can further prevent pests:

  • Keep vegetation and grass trimmed short around the shed perimeter
  • Avoid leaving debris or materials stacked near shed walls
  • Store feed and grain in sealed containers to prevent attracting rodents

Routine upkeep around the shed ensures pests have fewer hiding places and entry opportunities.
