Learn How to Identify, Avoid, and Treat Poison Ivy in Oklahoma

Introduction to Poison Ivy in Oklahoma

Poison ivy is a common plant that grows in many areas of Oklahoma. It's important for Oklahoma residents to be able to identify poison ivy so they can avoid coming into contact with it. Contact with poison ivy can cause an itchy, uncomfortable rash in most people. While poison ivy rashes aren't dangerous, they can be very annoying and unpleasant.

What Is Poison Ivy?

Poison ivy (Toxicodendron radicans) is a plant that is common throughout Oklahoma. It typically grows as a vine or ground cover. Poison ivy has compound leaves that contain three leaflets. The edges of the leaves have a few or no teeth. The leaflets are typically green and turn red in the fall. Poison ivy plants produce greenish-white berries.

All parts of the poison ivy plant, including the leaves, stems, and roots, contain an oil called urushiol. This is what causes the allergic reaction and rash in most people. Even when the poison ivy plant looks dead, the urushiol can still cause irritation.

Identifying Poison Ivy

Being able to correctly identify poison ivy is important to avoid exposure. Here are some tips for identification:

• Leaves are compound with three leaflets
• Leaf edges are smooth or slightly toothed
• Leaves are green and turn red in fall
• May grow as a vine or ground cover
• Has greenish-white berries

Poison ivy can sometimes be confused with other similar looking plants like Virginia creeper or boxelder. When in doubt, it's best not to touch a plant you can't positively identify.

Where Poison Ivy Grows in Oklahoma

Poison ivy can be found growing throughout most areas of Oklahoma. It is commonly found in:

• Fields
• Forests
• Prairies
• Along trails
• Along fence lines
• Near creeks and ponds
• In open woods
• In disturbed soil

Poison ivy tends to thrive in sunlight. However, it can grow in shaded areas as well. Be on the lookout for poison ivy in any outdoor location.

How to Avoid Poison Ivy Rashes in Oklahoma

The best way to avoid getting a poison ivy rash is to steer clear of the plant altogether. Here are some tips for avoiding exposure:

Learn to Identify Poison Ivy

Knowing how to identify poison ivy is the first line of defense. Pay attention to the characteristic compound leaves with three leaflets. Be on the lookout when in areas where poison ivy is known to grow.

Stay on Designated Trails

When hiking, camping, or doing other activities outdoors, try to stick to established trails. This can help reduce the risk of brushing up against poison ivy plants.

Wear Protective Clothing

Wearing long pants, long sleeves, gloves, and closed-toe shoes when outdoors can create a barrier against poison ivy contact. Be sure to wash clothing after potential exposure to avoid residual oil.

Watch Where You Put Your Hands

Be careful about placing hands on logs, trees, fences or other surfaces when outside. Poison ivy vines can grow on these surfaces.

Keep Pets Away

Dogs and cats can pick up the poison ivy oil on their fur after walking through or brushing up against it. Try to keep pets away to prevent carrying the oil back home.

Clean Tools and Equipment

Gardening tools, sporting gear, camping equipment and other items can easily pick up traces of the poison ivy oil. Be diligent about washing items after using outdoors.

Shower After Exposure

If you have walked through areas where poison ivy may have touched your skin, wash with soap and warm water immediately to help remove the oil.

Learn to Identify Similar Plants

Plants like Virginia creeper and boxelder can sometimes be mistaken for poison ivy. Learning how to positively identify look-alikes can prevent false alarms.

Treating Poison Ivy Rashes

If you come into contact with poison ivy and develop a rash, there are treatments available to help manage the symptoms. Here are some effective options:

Cold Compresses

Applying a cold, wet washcloth to the rash can help relieve itching. Cold compresses help soothe inflammation.

Oatmeal Baths

Taking a bath with colloidal oatmeal can help relieve itching. The oatmeal has anti-inflammatory properties.

Calamine Lotion

Dabbing calamine lotion on the rash can dry it out and reduce irritation. The zinc in calamine lotion acts as an anti-itch treatment.

Antihistamines

Taking an oral antihistamine like diphenhydramine (Benadryl) can help relieve itching. Antihistamines block the histamine chemical reaction.

Hydrocortisone Cream

Applying an over-the-counter hydrocortisone cream to the affected area can help decrease inflammation and itching.

Oral Corticosteroids

For severe poison ivy rashes, a doctor may prescribe an oral corticosteroid medication like prednisone. This can significantly reduce swelling, redness and itching.

Prevention Medications

Special medications like Tecnu can be applied to the skin before potential poison ivy exposure. These can help prevent the oil from penetrating the skin.

When to See a Doctor for Poison Ivy

In most cases, poison ivy rashes can be managed at home with over-the-counter treatments. However, you may need medical attention if:

• Rash worsens or becomes infected
• Rash develops into hives or blisters
• Itching is severe or interrupted sleep
• Rash occurs on face or sensitive areas
• Discomfort persists for more than 1-2 weeks

Signs of infection include pus, increasing warmth and redness, swollen lymph nodes and fever. Seek prompt medical care if these symptoms develop.

Long-Term Precautions for Poison Ivy

Taking some long-term precautions can help prevent repeated poison ivy exposures:

Destroy Poison Ivy Plants

Carefully removing poison ivy plants from areas around your home can eliminate a repeat threat. Wear protective clothing and dispose of plants properly.

Apply Herbicides

Using an herbicide product containing glyphosate or triclopyr can help kill and control poison ivy regrowth. Use cautiously according to directions.

Learn Your Sensitivity

Pay attention to how sensitive you are to poison ivy. Some people react worse than others. This can guide prevention and treatment measures.

Tell Others

Inform family members, friends or coworkers about known poison ivy areas. This allows them to take appropriate precautions as well.

Keep Pets Away

If possible, train pets to avoid areas where poison ivy may grow to prevent transmission.

Ask About Control Measures

Inquire with park services, camps, schools or other institutions about poison ivy control methods in areas you frequent.

Poison Ivy Removal and Control

Getting rid of existing poison ivy plants and preventing new growth is key for long-term avoidance. Here are some effective control methods:

Manual Removal

Manually digging up and removing poison ivy plants can eliminate them from an area. Be sure to wear protective gloves, clothing and eyewear.

Cutting

Repeatedly cutting down poison ivy plants whenever they regrow can help control growth over time.

Goats

Goats will readily eat poison ivy and can be used to naturally clear areas of infestation.

Smothering

Covering poison ivy with tarps or other materials blocks sunlight and smothers the plants.

Prescribed Burns

Controlled burning of areas in spring can destroy above-ground poison ivy plants.

Herbicides

Applying herbicides containing triclopyr or glyphosate to poison ivy can provide effective elimination.

Crowd Out

Planting dense ground cover plants like native grasses can crowd out and prevent poison ivy growth.

Conclusion

Poison ivy is a common nuisance plant throughout Oklahoma. Contact with its leaves or stems can cause an irritating, uncomfortable rash in most people. Learning how to identify poison ivy, avoid exposure and safely remove established plants are all key in poison ivy control and prevention. Being aware of poison ivy and taking proper precautions can help reduce the risk of developing the signature itchy rash.
