You can release them in numbers of 8-10 at a single time and prevent the release of a huge number in one go. These bugs have never been reported to cause any damage or harm to either the humans or their properties and therefore fall under the list of beneficial insects. Pest control agencies have successfully been using them to fight pests.

Soldier Beetles

Soldier Beetlesthe soldier beetles or Coleoptera are soft-bodied and about ½ inch long beneficial insects which can be of various colours like yellow, red, brown or even black. They are often related to Fireflies. These insects are used to combat a pest infestation because they are predators in nature.

This eventually kills the pests because the eggs hatch and the larvae excavate out through the body of the host. On the other hand, there are some species of these flies whose larvae live within the body of the host without excavating out from it which makes it weak and eventually brings death. Another interesting way in which they ensure that the pests swallow the eggs of their own is by dropping them in the nearby foliage where the insects come to eat. Every year two generations of tachinid flies can be expected under the favourable conditions. These beneficial insects are helpful to get rid of many harmful pests like Caterpillar of many kinds, cabbage worms, Colorado potato beetles, corn earworms, cucumber beetles, earwigs, four-lined plant bugs, Japanese beetles etc. The flies can effectively plant their eggs inside the bodies of these insects and wipe them out. They are easily attracted by flowering herbs, which are especially belonging to the dill family. Cilantro, dill, fennel, parsley are some other important plants which attract the flies.

The adult flies release the eggs over the surface of different leaves which hatch after a few days and the nymphs start to consume the aphids. Since the hoverflies can move at a very rapid rate in the air, they are difficult to get hold of by their threats. Small caterpillars including cabbage worms, as well as thrips, scale, and tiny mites,  are also under the list of their preys. The flies are attracted by bright flowers and usually the ones which have nectar in them. They will also clear out any kind of pests which might be living in these plants.
