Mechanical control involves the physical removal of invasive plants using tools like brush cutters or chainsaws and hand tools. Pestrex uses this method to clear dense vegetation and prevent re-infestation – we also provide greenwaste removal across Auckland for all pest-plant types.
Our team are certified to use herbicide sprays around your property to achieve complete control of pest plants or grasses in a safe manner. Amenity spraying can save your back from having to hand pull thousands of weeds creeping up through your paving! We also perform pre-planting sprays or site preparation sprays to kill off undesirable grasses such as kikuyu or perform targeted sprays to kill off turf weeds and broadleaf varieties. We choose the perfect active ingredient every time and apply safely to ensure environmental safety and best control.

Preparation
Ensure clear access to all areas being treated.
Keep pets, children, and livestock away during spraying.
Avoid mowing or cutting plants beforehand — healthy foliage absorbs spray better.
Let us know about nearby gardens, ponds, or sensitive plants.
Spraying will be rescheduled if rain or strong wind is expected.
Aftercare
Keep the area undisturbed and avoid watering for 7–10 days.
Effects may take 1–4 weeks to appear, depending on plant type.
Some infestations may need follow-up treatments.
Dispose of dead plants safely once control is complete.
Check with us before replanting to ensure the area is herbicide-free.
