Pests can enter Newcastle and Hunter Valley homes while searching for food, water and shelter. Although professional treatment may be necessary for an established infestation, several natural pest control techniques can help make your property less attractive to pests.
In this context, natural pest control means reducing pest activity through cleaning, maintenance, exclusion and physical removal rather than relying immediately on pesticide applications. These measures can support professional treatment, but they may not eliminate an established colony or infestation.
Keep Food and Rubbish Secure
Food scraps can attract ants, cockroaches, rodents, flies and other pests. Reduce available food sources by:
- Storing food in sealed containers
- Cleaning crumbs and spills promptly
- Washing dishes instead of leaving them overnight
- Emptying indoor bins regularly
- Keeping outdoor bins closed
- Cleaning underneath appliances
- Storing pet food securely
Regular cleaning will not eliminate every infestation. However, it removes food sources that can allow pest populations to survive and grow.
Seal Pest Entry Points
Small gaps around a building can give insects and rodents access to wall cavities, roof spaces and living areas. Inspect the exterior of your home for:
- Gaps around doors and windows
- Damaged flyscreens
- Openings around pipes and cables
- Cracks in walls or foundations
- Gaps beneath external doors
- Damaged roof tiles, vents or eaves
Seal suitable openings and replace damaged screens. Before closing a suspected rodent or possum entry point, make sure no animal is trapped inside the building.
Reduce Moisture Around Your Home
Many pests favour areas with reliable access to water. Leaking pipes, blocked gutters, damp subfloors and poorly drained gardens can contribute to pest activity.
Repair leaking taps and plumbing, improve ventilation where appropriate and prevent water from collecting against the building. Moisture management is particularly important because damp conditions can support cockroaches, mosquitoes and subterranean termites.
Natural Ant Prevention
Ants commonly enter homes while searching for food and water. Rather than relying on cinnamon, lemon or essential oils, focus on removing attractants and limiting access.
Wipe ant trails with soapy water, store sweet foods securely and seal gaps around windows, doors and plumbing. Avoid spraying visible ants if you have a substantial or recurring infestation. Killing individual workers may not affect the colony hidden elsewhere.
Read our guide on how to get rid of ants or arrange professional ant control if activity continues.
Rodent Prevention Without Repellent Remedies
Bay leaves, peppermint and household spices have not been shown to provide reliable control of an established mouse or rat infestation. Rodent prevention should instead focus on food, access and shelter.
Keep stored food and animal feed in durable sealed containers. Remove clutter, trim vegetation away from the building and inspect for possible entry points. Mice can enter through surprisingly small openings, so careful exclusion work is important.
If you notice droppings, gnaw marks or scratching noises, professional rodent control may be required.
Reduce Spiders Around the Property
Spiders often settle where prey insects and undisturbed hiding places are available. Reduce spider activity by:
- Removing unused boxes and clutter
- Vacuuming accessible webs and egg sacs
- Keeping outdoor lighting away from entrances where practical
- Repairing damaged screens
- Sealing gaps around doors and windows
- Keeping stored items off the floor
Do not handle a spider you cannot identify. If potentially dangerous spiders are present, arrange professional spider control.
Manage Garden Pests Carefully
Not every insect in your garden is a pest. Bees, butterflies and many other insects pollinate plants or prey on unwanted garden pests. Identify the insect and the extent of the damage before taking action.
For small outbreaks, you may be able to remove affected leaves, hand-pick caterpillars or snails while wearing gloves, install plant barriers or improve spacing and airflow. Avoid applying homemade garlic, chilli or detergent sprays because their strength is difficult to control and they may damage plants or affect beneficial insects.

Remove Mosquito Breeding Sites
Removing standing water is one of the most effective non-chemical methods of reducing mosquitoes. NSW Health advises emptying water-holding containers at least weekly because mosquitoes need standing water to complete their development. NSW Health
Check and empty:
- Plant saucers
- Buckets and unused containers
- Pet bowls
- Birdbaths
- Blocked gutters
- Tarpaulins
- Children’s toys
- Wheelbarrows
Also maintain flyscreens and use an Australian-registered personal repellent according to its label when mosquito exposure is likely.
When Natural Pest Control Is Not Enough
Preventative measures can reduce pest pressure, but they may not reach colonies hidden inside walls, roof voids, soil or subfloors. Professional assistance should be considered when:
- Pest activity continues or increases
- Rodent droppings or gnawing appear
- Cockroaches are regularly seen during the day
- You discover termites or suspected termite damage
- Biting insects are affecting occupants
- Wasps or potentially dangerous spiders are present
- The infestation affects a food-handling business
