Best Method To Get Rid Of Wasps Under The Deck: 5 Steps

Dealing with wasp nests under your deck can be a nerve-wracking experience. However, taking certain precautions and treating them appropriately is important before attempting to remove the nests. This section will explore several effective methods to treat wasp nests, ensuring a safer and more successful removal process. So, Here’s what you need to do!

Plan An Escape Route

First and foremost. It is crucial to plan your escape route when removing a wasp nest. Wasps are highly aggressive and can attack in swarms, causing painful stings. Each nest may harbor hundreds of wasps, and their numbers can quickly escalate. Thus, a planned escape route is necessary for a swift exit from the danger zone. So, ensure you are familiar with your surroundings and have a clear path to safety before taking action.

Wear Proper Protective Gear

When removing a wasp nest, having the right protective gear to shield yourself from potential stings is essential. Wasps can pose a significant threat, and their stings can be painful. Besides, in some cases, it can be deadly if you are allergic. Hence, here’s a list of recommended protective gear:

  • Long pants (preferably jeans) to cover your legs.
  • Boots to protect your feet.
  • Long-sleeved clothing to minimize exposed skin.
  • Gloves to protect your hands.
  • Hooded sweatshirt or a face mask with a scarf to shield your face.
  • Protective eyewear, such as safety goggles or glasses.

Creates a barrier between yourself and the wasps to reduce the risk of stings. Since using protective equipment is essential if you decide to tackle the task independently.

Identify The Specific Wasp

When faced with a wasp infestation under your deck, it’s essential to identify the specific wasp species present. This knowledge helps you understand their behavior and preferences and allows you to choose the most effective removal methods. First, observe the physical characteristics, such as color patterns, size, and distinct markings. Additionally, examine the nest structure, as different wasp species construct unique nests. Finally, take note of their behavior, including flight patterns, aggression levels, and preferred habitats.

What's the best time to remove a wasp nest?

Treat The Nest Before Removal

Before attempting to remove the wasp nest, treating it with either organic home-based or commercial pest control products is advisable. Treating the nest can help stun or eliminate many wasps, making the removal process safer and more manageable. Reducing the wasps’ activity and numbers decreases the likelihood of encountering aggressive behavior during the removal. Additionally, consider removing them in the late evening or early morning when wasps are less active and more likely to be inside the nest.

Remove Wasp Nest Effectively

After pressure spraying the nest, carefully detach it from its attachment point using a shovel or cardboard. The insecticide will have weakened the wasps, reducing their risk of swarming or stinging. Gently guide the nest into the bucket below to ensure it doesn’t fall onto the ground or escape. Quickly cover it with a lid or a piece of cardboard to prevent wasps from escaping. Seal it tightly to avoid any accidental release.

What are some home remedies for wasp nests under the deck?

How To Treat The Wasp Nest?

Like any other insect, wasps are sensitive to several small scents, smoke, and other products. Therefore, using these solutions can effectively force them away so that you can remove their nest. So, let’s look at 5 effective ways to get rid of wasps under deck:

Peppermint Oil Solution:

Peppermint oil is known for its strong scent, a natural repellent for wasps. To create a peppermint oil solution, follow these simple steps:

  • Mix 10 to 15 drops of peppermint oil with water in a spray bottle.
  • Shake the bottle well to ensure proper mixing.
  • Spray the solution directly onto the wasp nests, focusing on the entry points and surrounding areas.
  • The strong aroma of peppermint will discourage wasps from returning to the treated nests.

Vacuum Cleaner:

Using a vacuum cleaner to remove wasps and their nests can be an effective and safe method. Here’s how to do it:

  • Attach a long extension hose to your vacuum cleaner.
  • Make sure the vacuum cleaner is set to its highest suction power.
  • Approach the nest cautiously, using the extension hose to reach it without getting too close.
  • Direct the hose towards the nest entrance and slowly vacuum up the wasps and their nest.
  • Seal the vacuum bag or container tightly to prevent any escape, and dispose of it in an outdoor garbage bin.

Wasp Traps:

Wasp traps are designed to lure and capture these stinging insects. Here’s how to set up a wasp trap:

  • Purchase a commercially available wasp trap or create a DIY trap using a plastic bottle.
  • Fill the trap with a sweet liquid such as fruit juice, soda, or a sugar-water solution.
  • Place the trap near the wasp nest, ensuring it is easily accessible to the wasps.
  • The sweet scent will attract the wasps into the trap, trapping them inside and preventing them from bothering you on your deck.

Diatomaceous Earth:

Diatomaceous earth is a natural substance that can help eliminate wasps by dehydrating them. Follow these steps to use diatomaceous earth:

  • Locate the wasp nest and sprinkle a generous amount of diatomaceous earth directly onto the nest and surrounding areas.
  • The microscopic sharp edges of the diatomaceous earth will pierce the wasps’ exoskeleton, causing them to dehydrate and die.
  • Reapply the diatomaceous earth if necessary, especially after rain or strong winds.

Wasp Insecticide:

If the infestation is severe or other methods haven’t been successful, using a wasp insecticide can provide a more aggressive approach. Here are the general steps for using wasp insecticide:

  • Choose a wasp insecticide spray specifically labeled for wasp control.
  • Read and follow the instructions on the product carefully, as different insecticides may have specific usage guidelines.
  • Spray the insecticide directly onto the wasp nest, focusing on the entry points and nest structure.
  • Keep a safe distance and wait for the recommended time (at least 12-24 hours) on the product label before attempting to remove the nest.
How can I deter wasps from building nests under my deck in the future?

Effective Wasp Nest Deterrence Methods

When it comes to getting rid of wasp nests under your deck, prevention is key. This section will explore a simple yet effective method to deter wasps from rebuilding their nests. So, here’s what you need to do!

Create Faux Nests:

By creating fake nests using brown paper bags, you can mimic the presence of a rival wasp colony and discourage new wasps from settling in your deck area. To start, locate a larger brown paper bag. Look for one that is approximately the size of a wasp nest.

Blow the bag gently to give it volume, creating a funnel-like shape. It will help replicate the appearance of an active nest. Mold the bag into an oval shape resembling a wasp nest. Now tie a secure knot at the end to keep it intact. Identify suitable locations under your deck where the original nests were removed. Hang the fake nests using string, hooks, or any other appropriate hanging mechanism. If you have multiple areas under your deck where wasp nests are present, create additional faux nests and hang them accordingly. 

Use An Ultrasonic Pest Repeller:

An ultrasonic pest repeller is a non-toxic and non-chemical solution to keep wasps and other pests away. These devices emit high-frequency sounds and wavelengths that are generally undetectable to humans but can be heard by pests. Plugging in an ultrasonic pest repeller may deter wasps, mosquitos, spiders, ants, roaches, and even rodents. However, be cautious with high-powered versions, as they may be audible to humans and pets. Using them when you are not at home or have no pets is advisable.

Create A “Wasp Plate”:

If you are planning a barbecue on your deck, the presence of food can attract wasps. To minimize their interference, create a “wasp plate.” Place a small piece of raw meat far away from your deck, porch, or patio about an hour before your gathering. This tactic aims to divert the attention of the wasps to a location away from your dining area. Additionally, promptly clean up after your meal to reduce the chances of attracting wasps to your yard.

Add A Water Source:

Wasps often seek water sources while flying around, including swimming pools. Install a birdbath in a distant yard corner to provide an alternative water source. It will discourage wasps from considering your pool. Remember to change the water regularly to prevent it from becoming stagnant and attracting mosquitos.

Covering your pool when not in use is an effective way to make it less accessible to wasps. Opt for a pool cover with sufficient weight to ensure it stays in place, minimizing the chances of gaps forming that wasps can squeeze through.

Set Up Wasp Traps:

Wasp traps can be a valuable tool in reducing the number of wasps around your deck, porch, or patio. You have two options: creating homemade traps using empty two-liter bottles or purchasing premade traps. Regardless of the type, baiting the trap is crucial. Using sugar water, apple cider vinegar, or a small amount of beer can effectively attract wasps into the trap, preventing them from buzzing around your outdoor space.
