Scarlet Lily Beetle (LILIOCERIS LILII)
This scarlet coloured pest can feed on lily and fritillaria foliage in spring to early summer. Bulbs can become under-sized and flowering the following year can be jeopardised. These pests can be seen in their various stages of growth and are all equally dangerous. Reddish brown eggs lead onto grubs and then finally to bright red beetles with black head and legs.

Grazers G4 solution is:

  • Pet friendly
  • Child friendly
  • Eco friendly
  • Wildlife friendly

PLEASE NOTE:

If ordering for Lilies - If you wish to receive this in the Spring with the delivery of your lilies, please choose the relevant delivery month in the Spring when you check out to avoid incurring an additional P&P fee for delivery in the Autumn.

If ordering for Fritillaria - Please choose an Autumn dispatch month for delivery with your Fritillaria bulbs. 

How to Use Grazers G4 Lily Beetle Prevention Spray

Grazers G4 is a natural and safe spray that helps deter the dreaded red lily beetle from your precious lilies. It’s safe for pets, wildlife, and pollinators – and kind to your plants!

When to Use:

  • Begin spraying early in the season, as soon as shoots emerge in spring.
  • Continue applying every 7–10 days, especially after rainfall or heavy watering.

How to Apply:

  1. Shake the bottle well before use.
  2. Spray directly onto the leaves and stems of your lilies.
  3. Make sure to get good coverage on both upper and lower leaf surfaces.
  4. Apply in dry, calm weather to allow the spray to settle and absorb.
  5. Reapply regularly to maintain protection, especially after rain.

Top Tips for Best Results:

  • Don’t wait for beetles to appear – prevention is better than cure.
  • If you’ve had lily beetle problems in previous years, start early and spray consistently.
  • Use in combination with regular visual checks – remove and squash any beetles or larvae you spot!

Suitable for:

  • Lilies (Asiatic, Oriental, Tree lilies)
  • Fritillaries and other lily beetle-prone bulbs
