Fresh barium chloride does not contain another substances (impurities) like barium chloride stored in container. Hydrogen peroxide is very reactive and with some cations and anions gives oxygen and water instead of peroxide.
It would most likely be harder for the insect to walk on ethanol because the bonds holding the ethanol together are not as strong
