Nematodes as Beneficial Microbes
Nematodes are soil microbes that predate on various bugs in the larval stage in the soil. Capitol Bee CARE has been using two species (Heterorhabditis indica and Steinernema riobrave) of these beneficial microbes in the soil around our hives for the past decade with great success at controlling small hive beetles. Despite the fact that we invest a lot of time and some expense in producing these two nematode species we have included treating the soil around the hives as part of our best practices protocol since the presence of small hive beetles directly impacts hive health.
Three years ago we started testing the efficacy of a third strain of nematode that we are now producing that targets the larval stage of ticks and other pest insects in the soil.
