Paper wasps are a common nuisance around homes in warm climates. With proper control methods, you can get rid of paper wasp nests and keep these pests from returning. This comprehensive guide will teach you how to identify paper wasps, understand their behavior, and use the most effective removal techniques for long-term control.

Identifying Paper Wasps

The first step in any pest control strategy is proper identification of the species. There are several types of wasps that may be buzzing around your home. Here’s how to recognize paper wasps:

Appearance

Slender, honey bee-like body with long legs
About 1 inch long
Distinctive black and yellow or brown coloring
Narrow “waist” between thorax and abdomen
Wings fold longitudinally when at rest

Nesting Habits

Build nests out of chewed wood pulp
Nest resembles an open umbrella with exposed cells
Often build nests under eaves, ledges, or on branches
Nest openings face downward
One queen starts the nest in spring, workers enlarge it through summer

Behavior

Generally docile unless nest is disturbed
Will aggressively defend nest
Feed on nectar and other insects
Forage near nest during daytime hours

Once you confirm paper wasps are the culprits, it’s time to remove their nests and keep them from coming back.

Why Get Rid of Paper Wasps?

Paper wasps may not seem like a big deal at first. But these invasive pests can quickly become a nuisance:

Painful stings: Paper wasps will sting defensively if their nest is disturbed. Their stinger injects a painful venom.
Property damage: Nests built on home exteriors can discolor or erode surfaces. Chewed wood pulp nest materials also stain surfaces.
Ongoing infestations: Nesting sites are reused year after year if not removed. Controlling nests early prevents exponential growth.
Safety concerns: Nesting on porches or play equipment poses a risk for homeowners. Knocking down nests unintentionally also prompts attacks.

Keeping your property free of paper wasp nests through prevention and removal improves safety and preserves structural integrity.

When to Remove Paper Wasp Nests

Timing is an important factor in your control strategy:

Spring

Monitor for new nests beginning in early spring.
Removing new starter nests in spring prevents large summer colonies.
Queens emerge from hibernation and begin building nests under eaves, porch ceilings, etc.

Summer

Monitor existing nests and treat weekly if active.
High activity around established nests in summer months.
Large nests with up to 200 workers foraging during this time.

Fall

Nests are abandoned and die out naturally by late fall.
No need to treat vacant nests, which disintegrate over winter on their own.
Knock down remaining nests to prevent reuse next spring.

The key is not allowing nests to become fully established each spring and summer. Eradicating them early or preventing construction is ideal over dealing with mature, difficult-to-reach nests.

Natural Deterrents

If you spot a new nest beginning in a problem area, try these natural deterrents first:

Strong-Scented Sprays

Peppermint, eucalyptus, or citrus oil sprays repel wasps.
Spray nest entrances or potential nesting sites.
Reapply after rain until they abandon the area.

Prevent Access

Seal cracks, holes, and openings where nests start.
Use metal screen or hardware cloth to close access holes.
Caulk gaps around roof vents, light fixtures, rafters.

These tactics may prevent nests in the first place or cause wasps to move on during early stages. However, established or difficult-to-reach nests often require insecticide sprays or professional removal.

DIY Removal Methods

Removing paper wasp nests yourself is possible with proper gear for safety:

Supplies Needed

Wasp and hornet spray
Extension pole for spray nozzle
Ladder for reaching high nests
Heavy clothing and closed toe shoes
Protective hood with mesh face shield
Water hose on hand in case of emergency

Take precautions when working at heights on ladders or roofs. Have someone on hand to assist you. Also avoid using ladders near electrical wires.

Process

Wait for cooler evening temperatures when wasps are less active.
Use a flashlight to locate nest openings.
Attach spray nozzle to an extension pole for safe distance spraying.
Cover skin fully and don protective hood with face shield.
Spray nest openings directly with a sweeping motion until saturated.
Most knockdown sprays will kill wasps and nest within 24 hours.
Knock down and dispose of nest after allowing time for spray to work.
Seal areas so new nests cannot form in the same sites.

This process allows DIY removal without aggravating and provoking mass attacks from the hive. Follow all label directions for proper spray use.

Professional Exterminator Removal

For severe infestations or nests in dangerous locations, hiring a pest control professional is recommended.

Benefits of Professional Removal

Have required equipment and supplies for safe removal.
Can access difficult locations like roofs, tall trees, or confined spaces.
Knowledge of most effective spray and removal methods.
Avoid liability and risks of DIY removal done improperly.
Can provide follow-up preventative treatments if needed.

What to Expect

Initial inspection to identify all nest locations on the property.
Sealing entry points they use to build nests.
Applying a knockdown spray to exterminate nests.
Returning to remove nests and debris once vacant.
Follow up visits to monitor for new nests forming.

Though more costly than DIY, professionals have specialized tools, Protective equipment, and expertise to remove nests in hard-to-access areas. They can fully eradicate nests and implement preventative measures.

Home Remedies to Avoid

Some DIYers attempt removal with home remedies like soapy water, vinegar spray, or gasoline. Avoid these methods:

Soapy water – Irritates wasps but does not kill them or the nest.
Vinegar spray – The acidity repels wasps but is not an effective pesticide.
Gasoline – Extremely dangerous and not formulated to kill wasps. Also damages surfaces.
Bug zappers – Do not effectively control aerial nests and anger wasps.
Smoke or fire – Difficult to direct and may cause unintended fires.

These methods often stir up angry wasps without resolving nests. Only use pesticides formulated specifically for wasps and hornets. Follow all safety directions when using insecticides. Consider hiring a pro for big nests.

Preventing Paper Wasps From Returning

Eliminating nests is only half the battle. Prevent future infestations with these tips:

Seal Cracks and Crevices

Caulk holes in siding, roof vents, Ledger boards, and overhangs.
Screen rain gutters, attic vents, and openings they crawl into.
Use wire mesh to cover cavities and exclude large areas.

Remove Food Sources

Clean up fallen fruit, rotting wood, and debris that attracts insects.
Maintain proper sanitation by emptying garbage frequently.
Install tight-fitting lids on outdoor trash and recycling bins.

Deter Nesting Sites

Coat commonly used nest areas with petroleum jelly or insecticidal dusts.
Install boards, screens, or barriers to block access to Cavities.
Prune back trees and vegetation touching structures.

By denying access, hiding places, and food, it’s possible to prevent future nests in and around your home. Maintain vigilance in spring to identify and eliminate attempted nests early.

When to Call a Professional

DIY removal is not advised in some cases. Call pest control experts for:

Nests out of reach on roofs or tall trees.
Allergic individuals who could react severely to stings.
Large infestations on multiple areas of a property.
Swarming insects indicating an active hive somewhere.
Nests near sensitive areas like electrical equipment.
Dangerous nest locations that are difficult to approach.
Repeated nests returning despite DIY removal attempts.

Don’t risk personal injury or property damage from improper removal methods. Licensed pros have the necessary expertise, safety gear, insurance coverage, and state regulations to perform the job correctly.

How to Get Rid of Paper Wasps FAQs

Still have some lingering questions about controlling paper wasps? Here are answers to some frequently asked questions:

Are paper wasp nests reusable from year to year?

No, paper wasp nests are weather dependent structures abandoned at the end of each summer. New queens construct a new nest the following spring. However, they often choose the same locations and building sites repeatedly if not deterred.

How long does it take for wasp spray to work?

Most wasp and hornet sprays paralyze and kill wasps within 24 hours of application. The active ingredients cause instant paralysis then longer term metabolic disruption resulting in death. Look for a residual spray that keeps killing for weeks after application.

Can I use a hornet spray on paper wasp nests?

Yes, you can use a hornet and wasp spray formulated with synergized pyrethrins. The best sprays have a 20+ foot jet spray for reaching high nests. Avoid short range sprays requiring close contact.

What if I can’t reach the nest?

Extensions wands and poles allow you to safely stand 15+ feet from even high nest locations during application. For extremely tall trees or multi-story roofs, you will need to hire a professional service with ladder trucks or lifts capable of reaching the nest.

What should I do with dead nests after spraying?

Wait a few days after spraying, then knock down and discard any grayish, brittle nests. This keeps them from becoming reused. Sealing areas where they were attached also helps discourage the same spot being rebuilt next year.

When is the best time to spray a paper wasp nest?

The most effective and safest time to use insecticidal spray is in the early morning or late evening when wasp activity is lowest. High temperatures and full sun during mid day causes greater defensive behavior.

How can I prevent wasp nests from returning?

Installing small screens or barriers over common entry points discourages nest builders. Caulking cracks in siding and sealing openings in overhangs or vents also denies access. Pruning back vegetation close to structures also helps since wasps tend to nest in bushes and trees near the house.

Conclusion

Dealing with paper wasps takes some courage, but knowing proper removal strategies helps you take back control. Focus on early detection and prevention in the spring. Seek professional help for large or dangerous infestations. Stick with pesticide sprays proven effective and safe around humans and pets when applied properly. With vigilance, you can reclaim your outdoor living space and keep your home free of paper wasp nests for good.

How to Get Rid of Paper Wasps

Paper wasps can be annoying and dangerous pests around homes and gardens. Their exposed nests and willingness to sting when disturbed make them a nuisance. This guide covers how to identify paper wasps, remove existing nests, and prevent future infestations in yards and structures. Follow these control methods to safely and permanently get rid of paper wasps on your property.

Identifying Paper Wasps

There are over 200 species of paper wasps in the world. Here are some key traits that set them apart from other stinging insects:

Slender, honey bee-like bodies approximately 1 inch long
Distinct black and yellow or brown coloring
Long legs with narrow waists between thorax and abdomen
Nest made of chewed wood pulp resembling paper (thus the name)
Umbrella-shaped nests often built under eaves or ledges
Exposed, hexagon-shaped cells facing downward
Docile unless nest is threatened

Paper wasps can be confused with Polistes dominula, an invasive species also known as the European paper wasp. However, P. dominula has distinctive yellow antennae and yellow legs. Knowing the species helps ensure proper identification and control.

Why Eliminate Paper Wasp Nests?

Left uncontrolled, paper wasps will continue expanding their nests each year, creating bigger problems. Here’s why it’s essential to remove them:

Painful stings – Paper wasps aggressively defend their nest and readily sting if disturbed. Their venom can cause swelling, pain, and marks.
Ongoing nuisance – Nests left in place will be reused and added onto season after season. Populations rapidly multiply.
Property damage – Nest materials stain surfaces they are built on. Large nests also degrade home exteriors over time.
Health hazards – Some people may have severe allergic reactions to stings requiring medical care.
Safety issues – Nests built in play areas, porches, or doorways pose risks for homeowners.

Controlling nests early and preventing their return improves safety and preserves your property’s structural integrity.

When To Remove Nests

Paper wasp nests become very noticeable in late summer as populations peak. But attempting removal at this stage will be difficult and prompt aggressive defense.

Spring – Monitor for new nests beginning in early spring. Knock down these starter nests while small and manageable.
Summer – Established nests will be too challenging for DIY removal. Call a pro to treat active nests during peak summer months.
Fall – Nests die out when cooler weather arrives. Knock down remaining empty nests to prevent reuse next year.

The key is early detection and removal in spring before nests grow large and populous. Preventing construction in the first place is ideal.

Natural Repellents

For new nests detected early, try these natural deterrent measures first:

Peppermint oil – The strong scent of pure peppermint oil repels wasps. Spray it directly onto new nests or at entry points like eaves.

Citrus oil – Orange, lemon, and grapefruit oils also annoy wasps with their pungent aromas. Spray onto potential nest sites.

Eucalyptus oil – This common natural oil also has insect repellent properties. Apply to nest entrances as a deterrent.

Seal entry points – Use metal screen, caulk, or other materials to close up cracks and crevices where wasps gain access.

These DIY remedies may prevent new nests if applied early and diligently. However, call an exterminator for removing established hives.

Professional Removal

For severe infestations or difficult to reach nest locations, professional pest control is recommended.

Benefits of professionals:

Have required safety equipment and specialized tools.
Can access awkward areas like roofs, tall trees, or confined spaces.
Expert knowledge of most effective spray products and formulas.
Avoid liability and risks of improper DIY removal attempts.
Provide follow up treatments to prevent nests from returning.

What to expect:

Thorough inspection to locate all nests on the property.
Seal gaps, holes, and cavities where nests start.
Apply a residual insecticide spray to exterminate nests and lingering wasps.
Remove nests and debris once vacant.
Follow up visits to monitor and prevent new nests.

Though costly, professionals have the proper protective gear, training, insurance, and state licenses to perform removal safely and effectively.

DIY Removal Tips

With caution, home treatments are possible:

Supplies Needed:

Wasp and hornet spray
Extension pole for spray nozzle
Heavy clothing and closed toe shoes
Protective hood/face shield
Water hose on hand

Process:

Spray in early morning when wasps are least active.
Use a flashlight to locate the nest after dark.
Attach spray nozzle to an extension pole for distance.
Cover skin fully, wear a hood with mesh face shield.
Spray nest entrance directly, soaking nest thoroughly.
Most sprays work within 24 hours. Allow time before removing nest.
Knock down and discard dead nest carefully.
Seal areas so new nests cannot form.

With proper protective equipment and ideal timing, DIY nest removal is possible. Never approach a live nest without appropriate clothing and respirators to prevent stings.

Prevention Tips

Removing nests is only half the battle. Prevent future invasions with these tips:

Seal cracks, holes, and openings with caulk, screen, or foam.
Use steel mesh to cover large cavities they enter.
Prune back trees and bushes touching structures.
Clean up fallen fruit, open trash cans, and debris that attracts insects.
Install tight lids on all outdoor trash cans.
Apply petroleum jelly or insecticidal dusts to common nest sites.
Use boards, barriers, or screens to block access to cavities.

Follow an integrated pest management approach by denying food, access points, nest sites, and resources paper wasps need to thrive near your home. Check for and remove new nests early each spring before they grow and multiply.
