Ixodes holocyclus tick might "squeeze" saliva and gut contents into the host. Specifically, application of methylated spirit, nail polish remover, turpentine or ti-tree oil is thought to irritate the tick and make it inject more of the noxious substances. Spreading butter or oil over the tick is no longer recommended either. Application of pyrethrin (or pyrethroid) insecticides has been suggested 'as a narcotic and a toxicant, which prevents the tick from injecting its saliva' but with this method the tick may remain physically attached for 24 hrs before it drops off dead. Do not use pyrethrin containing products on cats as this
Solvent solvent-solute mixture consists of a single phase with all solute molecules occurring as "solvates" (solvent-solute complexes), as opposed to separate continuous phases as in suspensions, emulsions and other types of non-solution mixtures. The ability of one compound to be dissolved in another is known as solubility; if this occurs in all proportions, it is called miscible. In addition to mixing, the substances in a solution interact with each other at the molecular level. When something is dissolved, molecules of the solvent arrange around molecules of the solute. Heat transfer is involved and entropy is increased making the solution more thermodynamically
