Are June Bugs Safe for Rats?

Insecticides often contain the chemicals chlordane, DDT, and lindane. Because of the toxicity in the chemicals, a pet who consumes June bugs that have been marinated with them is at risk of getting sick.

Using a natural pest control method or a pet-friendly insecticide can keep the June bugs out of your yard and away from any toxic substances.

Overall, this is preferable for the pet rat because they can absorb harmful chemicals through the pads of their feet from conventional lawn and yard-care products.

Also, since chemicals can leak into groundwater, it is possible for the pet rat to unintentionally consume toxins if they drink from the small puddles in the yard.
