Schädlingslexikon – Green Guardia

Maiskäfer: Vorratsschädling in Mais & Getreide erkennen

Der Maiskäfer ist ein typischer Vorratsschädling, der vor allem in Mais, Getreide und daraus hergestellten Produkten auftreten kann. Die Schäden entstehen hauptsächlich durch die Larven, die sich im oder am Korn entwickeln und Vorräte langfristig unbrauchbar machen. Hier erfährst du, wie du einen Befall erkennst und natürlich gegensteuerst.

ⓘVerschiedene Vorratskäfer (z. B. Sitophilus-Arten) #Maiskäfer im Vorrat · Käfer im Mais

Was sind Maiskäfer?

Als „Maiskäfer“ werden umgangssprachlich verschiedene kleine Vorratskäfer bezeichnet, die Maiskörner und andere Getreideprodukte befallen können. Die Weibchen legen ihre Eier direkt in oder an die Körner ab. Die Larven entwickeln sich verborgen und bleiben lange unentdeckt.

Vorratsschädling Larven im Korn lange unbemerkt
Wichtig: Werden erwachsene Käfer sichtbar, ist der Befall meist schon fortgeschritten. Frühzeitige Maßnahmen sind entscheidend.

So erkennst du einen Befall

  • kleine braune bis dunkle Käfer in oder nahe Vorräten
  • Ausfluglöcher in Mais- oder Getreidekörnern
  • feiner Staub oder Krümel in Verpackungen
  • wiederkehrende Käferfunde im Vorratsschrank
Green Guardia Tipp: Kontrolliere auch selten genutzte Produkte wie Tier- oder Vogelfutter – sie sind häufige Befallsquellen.

Welche Produkte sind betroffen?

  • Maiskörner und Maisprodukte
  • Getreide, Reis, Hafer
  • Mehl, Grieß, Schrot
  • Tierfutter und Vogelfutter

Warum kommt es zum Befall?

  • Einschleppung über befallene Ware
  • lange Lagerzeiten
  • warme, trockene Lagerbedingungen
  • nicht luftdichte Verpackungen

Was tun bei Befall? (natürlich & sinnvoll)

1. Befallene Vorräte entfernen

  • alle sichtbar befallenen Produkte entsorgen
  • angrenzende Ware gründlich prüfen

2. Schränke reinigen

  • Vorratsschränke komplett ausräumen
  • Ecken, Fugen und Bohrlöcher aussaugen
  • feucht auswischen

3. Vorräte sicher lagern

  • nur noch luftdichte Behälter (Glas/Metall)
  • Bestände regelmäßig kontrollieren

Nützlinge als Empfehlung: Lagererzwespen

Lagererzwespen (Lariophagus distinguendus) sind bewährte natürliche Gegenspieler von Vorratskäfern, die Mais befallen. Sie parasitieren die Larven im Korn und unterbrechen so den Entwicklungszyklus – besonders dort, wo Larven für den Menschen unsichtbar bleiben.

Warum Lagererzwespen sinnvoll sind: Sie wirken gezielt im Verborgenen und ergänzen Hygienemaßnahmen sowie luftdichte Lagerung optimal.

FAQ zum Maiskäfer

Ist der Maiskäfer gesundheitsschädlich?

Die Käfer selbst sind nicht gefährlich, befallene Lebensmittel sollten jedoch entsorgt werden.

Wie lange dauert es, bis der Befall sichtbar wird?

Da sich die Larven im Korn entwickeln, kann ein Befall über Wochen unbemerkt bleiben.

Reicht Reinigen allein aus?

Reinigung ist wichtig, reicht aber bei fortgeschrittenem Befall oft nicht aus. Luftdichte Lagerung und ggf. Nützlinge sind entscheidend.

Was ist die beste Vorbeugung?

Kurze Lagerzeiten, regelmäßige Kontrollen und konsequent luftdichte Behälter.
