Anthemis  arvensis  L.  Compositce.  Corn  Chamomile.  Europe, 
nat.  in  U.  S.

The  powdered  flower  heads  possess  insect  killing  properties  equal 
to  that  of  Persian  insect  powder.  The  powder  is  very  effective 
against  bed-bugs,  fleas  and  flies,  but  ineffective  against  grain  worms 
and  other  caterpillars.  Ants  left  their  nest  into  which  the  powder 
had  been  blown.  Plant  lice  resisted  its  effect  the  least  of  any  of  the 
insects.  (Pharm.  Ztschr.  Russland,  Vol.  I,  No.  23,  April  1,  1863.
