Schädlingslexikon – Green Guardia

Kornkäfer: Befall in Getreide & Vorräten erkennen

Der Kornkäfer ist ein klassischer Vorratsschädling und tritt vor allem in Getreide, Mehl, Reis und anderen trockenen Lebensmitteln auf. Besonders tückisch: Die Larven entwickeln sich im Inneren der Körner und bleiben lange unbemerkt. Hier erfährst du, wie du Kornkäfer erkennst und wie du natürlich vorbeugst.

ⓘSitophilus granarius #Kornkäfer im Vorrat · Käfer im Mehl

Was sind Kornkäfer?

Der Kornkäfer gehört zu den Rüsselkäfern und ist flugunfähig. Er lebt ausschließlich in trockenen Vorräten. Die Weibchen legen ihre Eier direkt in einzelne Getreidekörner ab. Die Larven fressen sich im Inneren des Korns durch das Material, bis der erwachsene Käfer schlüpft.

Vorratsschädling Larven im Korn flügellos
Wichtig: Sichtbare Käfer bedeuten meist, dass bereits mehrere Generationen im Vorrat vorhanden sind. Deshalb ist schnelles Handeln entscheidend.

So erkennst du einen Befall

  • kleine, dunkelbraune bis schwarze Käfer (2–4 mm)
  • runde Ausfluglöcher in Getreidekörnern
  • feiner Mehlstaub in Verpackungen
  • Käfer in Schränken oder Schubladen nahe Vorräten
Green Guardia Tipp: Kontrolliere auch ungeöffnete Packungen – Kornkäfer können sich bereits im Handel eingeschlichen haben.

Welche Produkte sind betroffen?

  • Getreide, Reis, Mais, Hafer
  • Mehl, Grieß, Couscous
  • Nudeln und Backzutaten
  • Tierfutter und Vogelfutter

Warum kommt es zum Befall?

  • Einschleppung über bereits befallene Lebensmittel
  • lange Lagerzeiten
  • warme Lagerbedingungen
  • nicht luftdichte Verpackungen

Was tun bei Befall? (natürlich & sinnvoll)

1. Befallene Vorräte entfernen

  • sichtbar befallene Produkte konsequent entsorgen
  • nicht in der Küche offen stehen lassen

2. Schränke reinigen

  • Schränke vollständig ausräumen
  • gründlich aussaugen (Ecken & Bohrlöcher)
  • feucht auswischen

3. Vorräte richtig lagern

  • nur noch luftdichte Behälter aus Glas oder Metall verwenden
  • neu gekaufte Ware kurz kontrollieren

Nützlinge gegen Kornkäfer: Lagererzwespen

Lagererzwespen (Lariophagus distinguendus) sind natürliche Gegenspieler von Kornkäfern. Sie parasitieren die Larven im Korn und unterbrechen so den Entwicklungszyklus. Die Wespen sind für Menschen unsichtbar, stechen nicht und verschwinden von selbst, sobald keine Wirte mehr vorhanden sind.

Warum Lagererzwespen sinnvoll sind: Kornkäfer-Larven sitzen verborgen im Korn. Lagererzwespen erreichen genau diese Stadien und ergänzen Hygiene und richtige Lagerung optimal.

FAQ zu Kornkäfern

Woher kommen Kornkäfer?

Meist werden sie bereits mit befallenen Lebensmitteln eingeschleppt. Sie entstehen nicht durch mangelnde Sauberkeit.

Sind Kornkäfer gesundheitsschädlich?

Sie gelten nicht als gefährlich, befallene Lebensmittel sollten jedoch nicht mehr verzehrt werden.

Reicht Reinigen allein aus?

Reinigung ist wichtig, reicht aber oft nicht. Entscheidend ist zusätzlich luftdichte Lagerung und – bei stärkerem Befall – der Einsatz von Nützlingen.

Was ist die beste Vorbeugung?

Kurze Lagerzeiten, luftdichte Behälter und regelmäßige Vorratskontrollen.
