ingredients? is it stronger or different than the regular spectracide or other brands? does it kill the nest if the WASP takes it back to the nest?

Thank you for your question. The product's active ingredients are Deltamethrin and S-Bioallethrin. The product provides an instant kill and has residual action that will kill wasps and hornets returning to the nest. The product must be applied directly to the nest in order for it to be effective.
