Why reduce pesticide use?
Pesticides can harm wildlife and the environment, but they are common place on farmland and even surprisingly frequent in parks and gardens within cities.
The use of pesticides has caused a decline in insect numbers, which has had a knock-on effect on the populations of various bird species, such as house sparrows.
What can you do to help?
The easiest thing to do is reduce, or even avoid altogether, the use of pesticides within your Naturespace, or replace them with a range of wildlife-friendly alternatives.
Naturehood pesticide pledge
Avoid pesticide use wherever possible, using eco-friendly pesticides only when absolutely necessary.
Leave plants, insects, slugs and snails alone if they are not causing you harm.
Never use pesticides on plants when they are in flower because of the danger to bees, butterflies, hoverflies and other pollinators.
Promote natural pest control by encouraging natural predators to visit your Naturespace.
If you do use pesticides, try and choose eco-friendly and always follow the manufacturer’s instructions closely, using only what you need to reduce the damage to the wider environment.
Alternatives to pesticide use
You can use integrated pest management to lessen the impact of weeds, pests and diseases. This is essentially where you use a combination of methods together for greater impact. Take a look at some of our alternative pesticide suggestions that can be used alone or to complement each other.

Mulching and weeding
Growing plants such as carrots and brassicas under an insect-proof fine mesh can reduce and even eliminate some problems such as root flies. Planting in raised beds or elevated pots is another way to create a physical barrier from slugs and snails.
Ensure your Naturespace contains different plant types and use flowering plants to attract natural predators of pests such as hoverflies.
Plant strongly-scented plants such as marigolds, sage and lavender near your vegetables or flowers, as these can deter pest insects. Other plants can be used to distract potential pests. For example, Nasturtiums can lure butterflies away from laying eggs on your cabbages and act as sacrificial plants.
Early detection of fungal infections
Acting quickly to remove infected leaves before fungal infections take hold can prevent long-term and widespread issues. If a plant is prone to fungal infection, look at fungal-resistant varieties and consider adequate spacing between plants to allow air flow. If disease outbreak does occur, you can treat plants with products that work without chemicals. For more information take a look at the RHS website.
Natural pest control
You can help manage pests by introducing a natural predator. This doesn’t mean releasing a new creature into your Naturespace, but rather it involves creating conditions that are beneficial for the animals that will eat the pests in your garden to encourage them to visit your Naturespace.
The larvae of hoverflies are excellent aphid predators.
Birds will eat slugs and slug eggs.
Hedgehogs will eat slugs and snails.
The two-spot ladybirds are well loved by gardeners for eating greenfly and mealybugs.
