Purple Loosestrife Insects

We offer the very successful Loosestrife Defoliating Beetles, Galerucella pusilla and Galerucella calmeransis to combat this aquatic weed.
Loosestrife Defoliating Beetle
Galerucella pusilla
This species is shipped in late May, just as the adults begin their spring egg laying. The resulting larvae and adults severely damage the young loosestrife shoots, stunting them dramatically. Cartons of 105 adults are shipped during May for $150.
