If you are looking for an effective natural alternative to pesticides for common greenhouse, conservatory and some garden pests you’ve come to the right place!

Defenders offer a wide selection of tried and tested biological pest controls for use throughout the UK. All our biological controls are compatible with the needs of organic growers.

The aim of this website is to help you achieve good pest control. We give details of pests including descriptions, pictures, damage caused and life cycles along with detailed descriptions of their biological controls and how best to achieve the control.

Simply click on any menu item to find out more. We have solutions for: aphids, mealybugs, red spider mite, scale, sciarid flies, thrips, vine weevil, whitefly and even mites on reptiles!

To purchase products choose the Shop button in the green boxes or the shopping bag at the top right of any page.

We only deliver to addresses with United Kingdom Postcodes.

We can only supply stock within the United Kingdom (England, Wales, Scotland, Northern Ireland, Channel Isles and the Isle of Man) to comply with Regulations governing the release of non-indigenous animals and postal rules for different countries.

For both your and our security, CARD payments are processed by SagePay(Opayo) and can only be made online and NOT by phone, post or in person.

Around 70% of our products are not produced in the UK but are ordered each week by us on a Thursday for delivery the following week. The rest we produce ourselves.

Therefore, place your order online by MIDDAY on a THURSDAY for despatch by FIRST CLASS MAIL the following MONDAY or TUESDAY. If spare stock is available, orders received after the Thursday deadline will also be sent at the same time. Otherwise they will be carried forward until the next despatch date. We do not despatch orders later than Wednesday as if delayed in the post they may be held up over the weekend and arrive in poor condition.

Regardless of the number of items ordered a single postal charge to cover one delivery is  automatically added to the basket. If items are required on different dates please place a new order for each delivery, specifying the required week of despatch in 'Delivery Instructions'.

Larger items, orders for multiple products and packages with additional insulation required for extreme summer or winter temperatures, will not fit through a standard letterbox.  In the delivery information section, please specify a neighbour or an alternative cool, shady place for them to be left when they arrive. DO NOT ask for goods to be placed in a greenhouse, conservatory or other sunny location.

If we are unable to send all items together due to the non-availability of stock or other factors they will be sent separately at our expense as soon as they become available.

We are happy to give advice so email us at help@defenders.co.uk and we will respond as soon as we can.

Both of us look forward to your custom!
