Understanding Wasp Behavior

To tackle wasp problems effectively, it’s crucial to understand their behavior. Here's a deep dive into their lifecycle and the different types of wasps you might encounter.


Lifecycle of wasps


Wasps have a fascinating lifecycle that begins with the queen wasp. In early spring, after hibernating through the winter, the queen emerges to start building a new nest. She lays eggs, which hatch into larvae and eventually become worker wasps. 


These worker wasps take over the nest-building duties, gathering materials like wood fibers to create paper wasp nests. Throughout the summer, the colony grows, and by late summer, the nest can house thousands of wasps.


As the season progresses, new queens and male wasps are produced. The new queens will mate and then find a place to hibernate, while the rest of the colony, including the old queen, dies off in the fall. 


This lifecycle means that old nests are typically abandoned by the time winter rolls around.


Types of wasps


Understanding the types of wasps can help you identify and manage them more effectively. Here are the most common ones:


  • Paper wasps: These wasps are known for their distinctive paper-like nests, often found hanging from porch ceilings or under eaves. Paper wasps are generally not aggressive but will sting if threatened.

  • Yellow jackets: These wasps are more aggressive and build their nests in hidden places like attics or underground. Yellow jackets are often attracted to sugary foods and can become a nuisance at picnics and outdoor gatherings.

  • Hornets: While technically not wasps, hornets have similar behavior and nesting habits. They are larger and more aggressive, building large, ball-shaped nests in trees or on structures. Their stings can be painful.

  • Ground nesting wasps: As the name suggests, these wasps build their nests in the ground. They can be easily disturbed, making them a common problem for gardeners.


Do Old Wasp Nests Prevent Wasps?


Wasps are highly territorial creatures, and this trait plays a significant role in their nesting behavior. When a queen wasp starts searching for a suitable place to build nests in early spring, she’s on the lookout for prime real estate that's free from competition. 


If she encounters an old nest, it might signal that the area is already claimed, deterring her from settling there. This territorial instinct can be a natural way to prevent wasps from invading your space. 


The presence of an old nest can discourage new queens from establishing new colonies nearby, helping to keep your yard wasp-free without the need for harsh chemicals.


How Effective Are Old Wasp Nests at Deterring New Wasps?


The effectiveness of old wasp nests in deterring new wasps varies, and opinions on this topic are mixed. 


Some homeowners have observed that leaving an old nest in place discourage wasps from being building new nests nearby, thanks to wasps' territorial instincts. However, this method isn't foolproof. 


There are instances where new wasps, particularly paper nest-building wasps, may still decide to build their nests close to or even within old nests. This mixed outcome means that while leaving old nests might help in some cases, it's not a guaranteed solution.


When to Remove Old Wasp Nests


Removing old wasp nests is crucial for several safety reasons. If an old nest causes structural damage to your house, especially in vulnerable areas like the attic or behind walls, it's time to get rid of it. 


The weight and placement of a nest might weaken supports or damage insulation. Plus, these paper nests are a fire hazard if located near electrical fixtures or in dry spots.


Old nests can also attract other pests like ants, spiders, and moths. If you’ve noticed new insect activity around an old nest, it’s best to remove it to prevent a bigger infestation. 


Alternative Wasp Deterrents

If old wasp nests aren’t enough to keep new wasps at bay, don't worry. There are plenty of alternative methods to deter these pesky insects and keep your garden or yard enjoyable. 

Here are some effective strategies to consider.


Fake wasp nests


Use a fake wasp nest to deter new wasps from building nests around your home. These decoys mimic the appearance of real wasp nests, playing on wasps' territorial nature. 


Hang fake nests in strategic locations, such as under eaves, near your swing set, or on your porch ceiling, to discourage wasps from setting up shop nearby. Early spring is the best time to hang a fake nest, as this is when queen wasps are scouting for new nesting sites. 


Natural repellents


If you prefer a more natural approach, essential oils can be highly effective in repelling wasps. 


Oils like peppermint oil and citronella are known to deter wasps and other insects. Mix a few drops of essential oil with water and a bit of dish soap in a spray bottle and apply it around potential nesting areas, such as garden plants, eaves, and outdoor furniture. 


Another simple trick is to place dishes of sweet juices or slices of cucumber around your yard, as these can repel wasps while attracting them away from dining areas.


Preventative measures


Preventative measures are key to keeping wasps and other pests at bay. Start by sealing your trash cans tightly to eliminate food sources that attract wasps. Regularly clean up any food spills or scraps, especially around outdoor dining areas. 


Using wasp traps also help reduce their population. These traps can be placed around your yard and garden to catch and deter wasps effectively. Regular maintenance of your yard, such as trimming your grass, trees, and bushes, will help prevent wasps from finding suitable nesting sites.


Seek professional help


Sometimes, despite your best efforts, wasps still find their way into your space. If you’re dealing with a particularly stubborn or large colony, it’s wise to seek professional help. 

Pest control experts have the tools and knowledge to safely and effectively get rid of wasps, ensuring your home and yard remain safe and enjoyable. Professionals can also offer advice on long-term preventative measures to keep wasps and other pests away for good.
