The Maryland Department of Agriculture is urging residents to help reduce the spread of invasive species that pose a threat to agricultural and natural resources.
The agency says April is Invasive Plant, Pest and Disease Awareness Month.
The department says invasive pests often arrive on cargo ships or with people returning from foreign travel. But once here, they can spread due to people's carelessness.
The agency recommends that citizens learn where infested areas are and avoid them. If that's not possible, the department says people should remove all seeds and other plant parts from equipment and clothing before leaving an infested area.
The agency also suggests removing junk piles where bees can nest.
And if you're camping, buy or use firewood from near your campsite. Don't bring firewood from home.
