PART 4. WHAT OTHER INSECTS WILL USE MY BEE HOTEL?
It is very common for Australian native solitary wasps to share a Bee Hotel. Similar to the solitary native bees, solitary wasps can sting, but are not generally aggressive as they do not have a queen or a large nest to defend.

Wasps and bees have a major difference in their diet. Wasps catch insect prey to feed their young, whereas bees collect pollen. So if you have wasps nesting in your Bee Hotel, you should be able to see them bringing captured insects back to their nest.
Solitary native wasps are beneficial insects to have in a garden as they feed on caterpillars, aphids, cockroaches and spiders. So we are happy to have these wasps share our Bee Hotels with our local native bees.
Wasps that nest with clay
You will know that you have some solitary wasps nesting in your Bee Hotel, if some of the holes in your drilled timber blocks or bamboo canes are sealed with creamy clay plugs. Sometimes you will see a flat clay plug sealing a nest entrance. At other times, you may see an amazingly delicate clay funnel protruding from the nest hole.

This kind of nest may be built by a Potter wasp (subfamily Eumeninae). This is a solitary native wasp that catches caterpillars as food for its young.
Wasps that nest with grass
Another distinctive type of nest seal that you may see in the drilled holes or bamboo canes of your Bee Hotel is a dense plug of long grass stems or grass seed heads.

This kind of nest may be built by a Grass-carrying wasp (Isodontia). This is a solitary native wasp that catches crickets or grasshoppers as food for its young.
