HOW DO THEY 

GET HERE?

Although some invasive species can slip into the 

United States naturally via wind or ocean currents, 

it’s uncommon. Most get help from human activities, 

entering our country in cargo, mail, and passenger 

baggage. Agricultural produce, nursery stock, 

cut flowers, and timber can harbor these pests, and

invasive species also hitchhike on containers, crates, 

or pallets.

our crops, trees, and way of life.

DID YOU 

KNOW?

The cost of invasive species exceeds 

$1 billion annually. Farmers lose crops, 

prices for produce and goods increase, 

and the quarantines imposed on our 

agricultural exports can be devastating. 

Plus, there are cleanup costs associated 

with eradicating these hungry pests.

Invasive species throw our ecosystem 

off balance. These hungry pests feast on 

and infest our agriculture, damage our 

parks and forests, wreck our gardens, 

push out native species, reduce biological 

diversity, and change wildfire frequency 

and intensity. Some pests can even be 

dangerous to human health.

There are many ways you can help stop the spread of 

invasive species, no matter where you live—and that’s 

by preventing their introduction in the first place.

We can fight back against 

these hungry pests and 

keep them from destroying 

our ecosystems, crops, and 

local plant life.

Buy Local, Burn Local. Invasive pests and 

larvae can hide and ride long distances in 

firewood. Don’t give them a free ride to start 

a new infestation—buy firewood where you’ll 

burn it.

Plant Carefully. Buy your plants from a 

reputable source and avoid using invasive 

plant species at all costs.

Do Not Bring or Mail fresh fruits, vegetables, 

or plants into your State or another State 

unless agricultural inspectors have cleared 

them beforehand.

Cooperate with any agricultural quarantine 

restrictions and allow authorized agricultural 

workers access to your property for pest or 

disease surveys.

Keep It Clean. Wash animals, tires, and gear 

between fishing, hunting, or camping trips. 

Clean lawn furniture when moving it from 

one home to another. 

Learn To Identify. If you see signs of an invasive pest 

or disease, write down or take a picture of what you 

see, and then report it to your local USDA Animal 

and Plant Health Inspection Service (APHIS) office 

(aphis.usda.gov/planthealth/sphd), State agriculture 

department (nationalplantboard.org/member), or 

local master gardener (nifa.usda.gov/LGU-map). 

Speak Up. Declare all agricultural items to customs 

officials when returning from international travel.

WHAT CAN YOU DO?

HOW ARE WE

AFFECTED?

Arizona has a diverse agricultural landscape that 

contributes $17.1 billion to the State’s economy. It 

also ranks high among the Nation’s top producers in 

field greens, cotton, tree nuts, dates, citrus, grains, and 

agricultural seed. The State is known for contributing 

to the market place superior, top-quality agricultural 

commodities. Southwest Arizona is nationally known as 

the “Salad Bowl” for the amount of quality leafy green 

vegetables produced in that area.

Currently, Arizona and USDA are battling pests and 

diseases on different fronts in a cooperative effort. Citrus 

greening poses a serious threat if introduced into the 

State. With no known cure and the length of time before 

symptoms are evident after infection, impacts could be 

severe. The disease reduces the quantity and quality of 

citrus fruits and will eventually kill an infected tree.

A new threat comes from the old world bollworm. It is 

a significant threat to agriculture because it has a wide 

host range that includes a number of Arizona’s high-value 

crops, including cotton, corn, small grains, peppers, and 

tomatoes, among others. Additionally, this pest bears 

a close resemblance to other cutworms, including the 

corn earworm, which is a common pest in the State. 

Global economic damage from the old world bollworm is 

estimated at $2 billion annually.
