How do I mix Malathion 57% for flea infestations on animals and carpets?


Malathion 57% is not labeled for use indoors or for use on animals. Tengard SFR is labeled for fleas and can be used indoors and on dogs (do not use on cats). It is important to vacuum prior to the application to help draw the fleas up from the carpet so that they may come into contact with the insecticide.  Tengard can also be used to control fleas in lawns, which is often the source of a flea infestation. Adding an insect growth regulator such as Martins IGR can help disrupt the fleas breeding cycle and help control new infestations of fleas for up to 7 months.
