Since a square-headed wasp are predatory creatures, appropriate trap food would include smaller insects or a substrate that mimics the presence of their prey. However, using trap food is typically not a recommended method as it can disrupt natural predator-prey dynamics.

The larvae of a square-headed wasp develop inside cavities in dead wood or in the pith of stems where the adult females have provisioned cells with prey. To search for larvae, look in sunny areas where logs, dead branches, or old stems are present, as adult females prefer such nesting sites. For pupae, you should focus on the same nesting locations but look for closed cells as this is where the larvae metamorphose. Adult a square-headed wasp can be found near flowers and overripe fruit, as well as in woodlands, gardens, and hedgerows where they hunt for other insects, which indicates their activity areas during their final stage of development.

The suitable time to find a square-headed wasp would depend on their active periods which is usually during daylight hours when temperatures are moderate. It’s best to conduct searches when a square-headed wasp are likely to be foraging or active, which is often late morning or early afternoon.

Dry and sunny weather conditions are often more suitable for finding a square-headed wasp as many species within this order are less active during wet and cold conditions. It's best to plan your search on a day with favorable weather for insect activity.
