Mint Flea Beetle
Longitarsus ferrugineus (formerly L. waterhousei)
A tiny jumping beetle whose larvae feed on mint roots and whose adults chew holes in the leaves.
How to control mint flea beetle
- Use
- Ecomask Spray (also works: Ecomask Topdressing)
- When
- April to May.
- Where
- Spray the soil in the mint bed and water it in.
What it looks like
Adults are tiny, shiny, tan to reddish-brown beetles about 1/16 inch long that jump when disturbed. Larvae are small, slender, white grubs in the soil.
Damage
Adults chew small shot holes in mint leaves in summer. Larvae feed on roots and rhizomes in spring, which stunts plants and cuts oil yield.
How nematodes help
The eggs spend the winter in the soil. In spring the larvae feed on the roots, then turn into pupae in the soil.
No published studies of nematodes against this beetle were found. Nematodes target the larvae, which live in the soil.
Extension guides time soil treatments for spring (April to June), when the larvae are feeding on roots.
How to apply
Treat with Ecomask.
When: April to May.
Where: Spray the soil in the mint bed and water it in.
