Beer And Bugs: A Buzzing Repellent Theory

It's a warm summer's day, the sun is shining, and you're enjoying a cold beer in your garden. But wait, what's this? A wasp has landed on the rim of your glass, threatening to ruin your peaceful afternoon. Does drinking beer increase the likelihood of a wasp attack? And if so, are there any benefits to this unwelcome attention?

Why are wasps attracted to beer?

Wasps are attracted to beer because they feed on sugar. They are drawn to fermented sugar in the same way they are attracted to rotten fruit. The sugar in beer is produced by the fermentation process, which converts sugar into alcohol. Therefore, wasps are not attracted to the beer itself but the sugar it contains.

Wasps are more likely to seek out beer and other sources of sugar in the late fall when food sources become scarce. During the spring and summer, wasps are primarily focused on protecting and feeding the wasp larvae within their nests. The larvae need protein to develop, so the wasps prey on other insects to feed them. In return, the larvae secrete a sugary substance, which is the wasps' primary food source during this time. Additionally, nectar from flowering plants provides another source of sugar for wasps.

However, in the late fall, when the larvae have fully developed into wasps, they no longer provide a sugary food source, and flowers are less abundant. As a result, wasps are driven to seek alternative sources of sugar, such as rotten fruit and beer. The wasps that are attracted to your beer are likely towards the end of their short lives. They have completed their function of feeding and protecting the next generation of wasps, and most will die by early winter.

It is worth noting that beer traps are commonly used to lure and trap wasps, taking advantage of their attraction to beer. These traps involve placing beer in a container, such as a cut-off bottle, which the wasps will enter and become intoxicated, unable to escape. While effective, these traps have been criticised by some insect experts, who argue that they can also capture bees and other beneficial insects.

How to make a wasp trap with beer

While drinking beer won't repel wasps, it can certainly intoxicate them. And you can use this knowledge to make a DIY wasp trap using beer. Here's how:

Materials:

• 2-liter plastic bottle
• Marker
• Sharp knife or scissors
• Packing or duct tape
• String
• Beer

Method:

• Remove the labels from the plastic bottle.
• Draw a line with a marker just under the neck of the bottle, where it becomes a straight cylinder.
• Cut the neck off the bottle along the marked line.
• Flip the neck upside down and place it into the bottom of the bottle, creating a funnel. Make sure to remove the cap.
• Tape the two pieces together along the cut edges.
• Make two holes on opposite sides of the funnel's edge and tie a string through the holes to create a handle for hanging.
• Pour beer into the funnel, leaving about 1-2 inches of space below the funnel.
• Hang the trap outdoors in an area where you want to prevent wasp activity, such as near your picnic table or a tree in your yard.
• Check the trap regularly and dispose of any drowned wasps. Refill the trap with fresh beer as needed.

Note: When handling the wasps, even if they appear to be dead, always wear protective clothing and exercise caution. Wasps are aggressive by nature, and their stingers remain active even after they die.

Why wasps are dangerous

While it's true that wasps are attracted to beer, it's not a good idea to leave it out to trap and intoxicate them. Wasps are dangerous insects, and here are several reasons why:

Aggressive and Territorial

Wasps are known to be fiercely territorial and protective of their nests and young. They will attack with little to no provocation if they perceive a threat to their territory, and they can be extremely aggressive in their defence. This behaviour is particularly dangerous because they will often swarm and attack in large numbers. Unlike bees, wasps have smooth stingers and can sting repeatedly, causing hundreds of stings in a short time.

Wasp Sting Pain and Side Effects

The pain from a wasp sting is intense and sharp, and it can last for about 10 minutes. The stings typically cause pain and swelling around the area of the attack. In addition to the immediate pain, the wasp's venom will result in a sharp burning sensation, which will then subside into a dull throbbing.

Allergic Reactions

For those with allergies, a wasp sting can be even more dangerous. Wasp stings can cause severe allergic reactions, including anaphylaxis, which is life-threatening. Symptoms of anaphylaxis include lightheadedness, difficulty breathing, anxiety, confusion, and loss of consciousness. Even without an allergy, a large number of wasp stings can be lethal. The USDA states that the average non-allergic person can withstand 10 stings per pound of body weight.

Pheromone Release

When wasps feel threatened or agitated, they release alarm pheromones to call other wasps to gang up and protect the nest. This behaviour further increases the danger of a wasp attack, as it can quickly escalate from one wasp to a swarm.

Food Aggression

In the fall, when resources decline, wasps become hungrier and more aggressive in their search for food. They are drawn to sugar, which is why they are attracted to beer and rotting fruit. During this time, they will defend available food resources, increasing the likelihood of an attack.

In summary, wasps are dangerous due to their aggressive and territorial nature, the pain and potential side effects of their stings, the possibility of allergic reactions, their ability to swarm and release pheromones, and their increased aggression during food scarcity in the fall. It is important to take precautions to avoid provoking wasps and to seek professional help if a nest is present.

How to prevent wasps from being attracted to beer

Wasps are attracted to beer, but there are several things you can do to prevent them from buzzing around your beverage.

Firstly, it is important to understand why wasps are attracted to beer. Wasps are primarily attracted to the sugar within the beer, which they seek out as a source of food. Fermentation is the process that converts sugar into alcohol, and wasps are attracted to beer in a similar way that they are attracted to rotten fruit. Therefore, wasps will also be attracted to cider and other drinks with high sugar content, such as orange juice.

Now that we understand why wasps are attracted to beer, let's discuss some ways to prevent them from doing so:

• Avoid drinking beer outdoors during the late summer and fall: Wasps are more likely to be attracted to beer during these seasons as their usual food sources become scarce.
• Use a lidded container: This will prevent wasps from accessing your beer. Alternatively, you can use a straw to drink your beer, although this may alter the taste.
• Avoid wearing yellow and using yellow drinkware: Wasps like the colour yellow, so avoid drinking from yellow cans or wearing yellow clothing to reduce the risk of attracting them.
• Keep food covered: Wasps are attracted to sugar and meat, so keep food covered when eating outdoors.
• Dispose of trash properly: Ensure all trash receptacles have tight-fitting lids to prevent wasps from accessing them.
• Use wasp traps: While this may attract more wasps to your yard, setting up wasp traps filled with a mixture of beer and a few drops of dish soap can help lure and trap wasps. Place these traps well away from your patio or picnic table.
• Add dish soap to your beer: If you are drinking beer outdoors, adding a few drops of dishwashing liquid to your drink will make it harder for wasps to escape if they do venture in.

Why wasps are more attracted to beer in the fall

Wasps are a common occurrence during outdoor beer-drinking, with the insects showing a particular interest in the beverage. But why are wasps more attracted to beer in the fall?

Wasps are attracted to beer because they feed on sugar. Fermented sugar does not repel them, but it can intoxicate them. They seek sugar sources such as beer in the late fall when food sources become scarce. This is because, for most of the season, from spring through summer, wasps are busy protecting and feeding the larvae within their nests. The larvae need protein to develop, so the wasps prey on insects to feed them. In return, the larvae secrete a sugary substance, which is the wasps' primary food source during this period.

In late fall, the larvae have fully developed into wasps, so they no longer provide a sugary food source. Flowers are also less abundant, so wasps start to seek alternative sugar sources, such as rotten fruit and beer.

The wasps that go after your beer are likely towards the end of their short lives. They have completed their function of feeding and protecting the next generation of wasps, and most will die by early winter.

To avoid attracting wasps to your beer, opt for stronger alcoholic drinks with less sugar. You can also make a DIY wasp trap using a bottle with some cider or sugar water to lure the wasps away from your drink.
