Parasites 



Guinea pigs frequently are troubled with lice. 

 Lice may be controlled by dipping or dusting the 

 animals with an insecticide. Insecticides that are 

 efi'ective in controlling lice on guinea pigs are: 

 Methoxychlor, Korlan, lindane, malathion, and 

 rotenone. 



If you use any insecticide, keep a careful record 

 listing the insecticide, strength, and date of treat- 

 ment. Manj^ buyers need this information for plan- 

 ning experiments so the insecticide will not interfere 

 with the results. 



Dipping 



Dipping is the most effective way to treat guinea 

 pigs for lice. One dipping usually gives good 

 control. 



Clean the cages and spray with an insecticide. 

 You can use any of the insecticides recommended 

 for a dip to spray the cages.
