grrrr ground squirrels

[Lotsapaints]

Other than sitting out by my coops and shooting them there isn't much I can do the hawks catch as many as possible this is just a bad year for them here..they are covered with "stick-tights" itty bitty fleas that stick like ticks. I always use frontline on all the dogs because they are Jack Russell's and hunt very well and this year even with treatment the fleas and ticks have been fierce. I have chickens in a lot close to back fields so checking my Rooster out today seeing if he's up to SOP I see little black spots like fleas leave on a dog or cat could this be from the stick-tights? I dusted him and tonight will dust the hens as it's pretty hot right now all I know is I'm hating those darn squirrels.....
