balEnce BioPesticide is a host-specific pathogen that kills adult flies and fly larvae but is safe for humans, animals, beneficial insects, and the environment.  balEnce is available in a concentrated liquid spray for adult flies and fly larvae.

The active ingredient in balEnce, Beauveria bassiana, is a fungal spore that infects the adult fly and fly larvae on contact. The fungus consumes and kills the insect. Flies do not develop resistance to balEnce as with most chemical pesticides — so rotation of pesticides is not necessary or desirable.

Use Beneficial Insects to Combat Pests

Beneficial insects are very important in helping to control fly populations. Because balEnce is natural, organic, it won’t harm beneficial insects.

Terregena provides parasitic wasps in its arsenal of agricultural insect control products. Hister beetles and earwigs are also beneficial insects that will naturally be attracted to your barn as long as no chemical pesticides are used as PESTICIDES WILL KILL YOUR BENEFICIAL INSECTS!

Darkling Beetle Products for Poultry

Darkling beetles transmit many poultry diseases as well as harbor several parasites.

Broiler, turkey, brooder, and grow-out houses are ideal environments for the darkling beetles to breed, thrive and multiply. These habitats provide optimal temperatures and food for this pest and the beetles’ livability is near 100 percent from egg to adult. This results in very large numbers of insects in the house.

Darkling Beetle

Darkling beetles eat some beneficial insects, including the hister beetle. They do not eat parasitic wasps.

Examples of diseases caused by darkling beetles include leucosis (Marek’s), Infectious Bursal Disease (Gumboro), coronavirus, Newcastle Disease Virus, avian influenza, Salmonella sp, E. coli, Aspergillus sp, Eimeria spp., roundworms, and tapeworms.

Fly and Darkling Beetle Control with balEnce —

balEnce is a solution of the spores (conidia) of Beauveria bassiana (Bb) — a naturally occurring, environmentally friendly fungus that is present in soils throughout the world. Beauveria bassiana occurs in numerous strains which target and are fatal to certain insects — these specific insects are called the “host”.

The spore is picked up by the target, host insect, reproduces inside it, and kills the insect. Generally, and depending on the target insect and the ambient temperature, the Bb-infected insect ceases reproduction and succumbs in three to five days.

The Beauveria bassiana spores present in the environment are only sufficient to infect and kill a very small percentage of its target insect. By adding balEnce to the environment where the target insect is an issue, one is increasing the amount of this natural insect predator to a level that is sufficient to control them.

Because balEnce is an insect-specific pathogen, it has no negative impact on humans, animals, or other insects.
