Colloidal silver kills them all
Avail yourself of it
Three things people should have are Colloidal silver, food grade DE and activated charcoal.
All 3 have health benefits and other uses. The important thing is to do a little research to find the right doses and uses.
Also all 3 can be used safely on pets but there are precautions that might need to be taken. With DE I know that keeping water available and making sure they are drinking it is important, especially with cats.
