Agralan Ant Nest Control Nematodes
- In stock, ready to ship
Ant nests in lawns and borders can quickly become a nuisance, creating unsightly mounds of soil and disturbing plant roots. As colonies grow, they can weaken surrounding plants and make lawns uneven underfoot. Ants also contribute to other pest problems by protecting aphids from natural predators like ladybirds, allowing infestations to thrive.
Agralan Ant Nest Control Nematodes provide a natural, chemical-free way to tackle ant infestations. These microscopic, transparent worms (Steinernema feltiae) actively enter the ant larvae and release bacteria that stop them from feeding, leading to a rapid decline in the colony. Suitable for controlling both black and red ants, this biological solution works beneath the soil surface to target the nest directly while remaining completely safe for pets, wildlife and beneficial insects.
Mix the nematodes with water and apply using a watering can directly onto a well-watered ant nest. For best results, ensure the soil temperature is at least 12°C before application. Treatments can be carried out between April and September when ants are active. In cases of severe infestation, a repeat application after 4–6 weeks is recommended. Keep the treated area moist to help the nematodes move through the soil and maximise effectiveness.
Yes. Beneficial nematodes are safe around children, pets, birds, and other wildlife when used as directed. They target specific insect or slug species and do not affect mammals, birds, or plants.
Yes. Several nematode species are particularly well suited to greenhouse use, including those for fungus gnats, sciarid fly, thrips, and housefly. Apply to the growing medium and keep it moist after treatment.
Mix the pack with water according to the label, then apply with a watering can fitted with a coarse rose, a hose-end applicator, or a sprayer on a coarse setting. Water in afterwards and keep the soil moist for two weeks.
Yes. Nematodes are one of the most widely used biological control methods in UK gardening. They are living organisms that target specific pests naturally, without chemical residues, making them a strong fit for organic and wildlife-friendly growing.
For below-ground slug control, nematodes are generally the stronger option. They target slugs in the soil where most feeding and egg-laying happens, leave no chemical residue, and are safe for wildlife, children, and pets.Read our nematodes for slugs blog for a full breakdown, or see our guide to slug pellets if you want to compare approaches.
