Emerald Ash Borer (EAB) was found in Boulder, CO, in September 2013. As a non-native insect, EAB lacks predators to keep it in check. EAB only attacks ash trees in the genus Fraxinus (so mountain ash are not susceptible). EAB is responsible for the death of millions of ash trees in the Midwest. Help protect Colorado's ash trees! Don't move firewood, and consider chemical treatments to protect high-value ash trees.

On Tuesday, June 5, 2018, the United States Department of Agriculture (USDA) National Veterinary Services Laboratory (NVSL) confirmed the presence of the Longhorned tick (Haemaphysalis longicornis) in Arkansas. The Longhorned tick is an exotic East Asian tick associated with bacterial and viral tickborne diseases of animals and humans in other parts of the world. This tick is considered by USDA to be a serious threat to livestock because heavy tick infestations may cause stunted growth, decreased production and animal deaths. Like deer-ticks, the nymphs of the Longhorned tick are very small (resembling tiny spiders) and can easily go unnoticed on animals and people. This tick is known to infest a wide range of species and has the potential to infect multiple North American wildlife species, humans, dogs, cats, and livestock.
