Steam must be applied directly to bed bugs, insects and their eggs to be effective. Steam has no residual effect on bed bugs or other insects. Steam is only effective when it comes in contact with a living bed bug, insect or their eggs for the appropriate residency time. Steam can be effective in reducing bacteria counts when exposed to high enough temperatures and residency times.  Bayzi offers no expressed or implied warranties as to the efficacy of steam in reducing or eliminating bacteria, microbes or pathogens.
