When to use Atheta?

Atheta is most effective when introduced preventatively, prior to the establishment of pest populations.

How it works

How it works

How does Atheta work?

Atheta is a soil-dwelling species of rove beetle with an aggresive appetite that is attracted to the decomposing of biological matter where their prey is typically found. As they can travel readily within the environment they are released into, they can easily populate and colonize their release area.

Life cycle

The complete life cycle of Atheta takes about 21 days (at about 70°C/158°F). The sex ratio will typically be equal, 1:1 females to males. Eggs hatch in 3-4 days to begin their larval stages. Larvae resemble adult form, and their pupal chambers are constructed out of silk.


Atheta coriaria are typically light to dark-brown – in many cases al- most black – in color. The adult beetle can be anywhere between
3-4 mm. long. They have an elongated, slender body shape, and they have wing coverings along their backside.

Application Atheta

The beetles should be applied right away upon receipt, though if necessary can be held at 10°C/50°F for up to 7 days. Typically, one application at the beginning of the growing cycle, and a small re-application at each transplant is sufficient to enable Atheta populations to establish effectively. To increase likelihood of reproduction, release at least 50-100 beetles at each application site.

The information given below is merely indicative. Tailored advice can be provided if information is available on the local factors that need to be taken into account, such as the crop, the climate conditions and the level of infestation.

Best working conditions Atheta

They are well suited for release into a variety of growing situations, (ex. beds, pots, seedling/cutting propagation areas, etc.). Due to their ability to move quickly, fly when needed, these predatory rove beetles can be monitored by scraping back the top 1-2 cm. of the growing media. Adults are non-diapausing under greenhouse light conditions. Population will fluctuate throughout the growing season, depending in large par on the prey population density.
