Determine the concentration of essential oils and emulsifier needed in the final formulation. This depends on factors such as the potency of the essential oils and the target pests. Start with lower concentrations and gradually increase if necessary.

Take care that commercial products usually also contain additional additives (preservative - usually necessary for essential oils in the field, wetting agent...) that have an impact on the efficacy

You can try with polymers, to test whether polymers are a good medium for oils.

You can try dimethyl flafoxide

Good point - but what efficacy would that be?
