infest

A parasitic fly whose maggots can infest living livestock, birds, pets and humans, could threaten California soon.

Inmates are housed in unsafe, dirty facilities infested with roaches and rats, Bonta said in a news conference Monday, and lack basic access to clean water and edible food.

When trees are infested with a few thousand beetles they can cope, using resin to flush the beetles out.

Those most at risk are people working with livestock or those living in rural areas where infested livestock are present.

"NWS can infest livestock, pets, wildlife, occasionally birds, and in rare cases, people."
