How to Get Rid of Botfly Eggs (DIY)
There is a special comb made to remove the bot eggs, but combing is time-consuming. Instead, I put either baby oil or petroleum jelly on the eggs, which prevents them from hatching. I noticed a couple of years ago that when I put baby oil on the bot eggs there`would be no new eggs for a day or two.
Now during bot season, I put baby oil on my horses daily, from their knees to their hooves. I have found that the botfly will not lay its eggs in the oil. Only a few drops on each leg saves hours of extra grooming time needed to remove the eggs with a comb.
This DIY technique keeps botfly eggs away from horses.
