No one wants to experience a wasp infestation in their home or garden. Wasps can be aggressive and their painful stings can cause allergic reactions in some individuals. It’s important to recognize the signs of a wasp infestation in order to take timely and effective action to deal with these unwelcome visitors. In this article, we’ll discuss some common signs that you may have a wasp problem, as well as provide some tips on how to manage and prevent wasp infestations.

Nests

The most obvious sign of a wasp infestation is the presence of nests. Wasps build their nests using a mixture of wood and saliva that creates a paper-like substance. These nests can vary in size and shape, but they are typically grey or brown and have a honeycomb structure on the inside.

Where to look for nests

Wasps can build their nests in various locations, both indoors and outdoors. Some common places to find wasp nests include:

  • Eaves and soffits of buildings
  • Roof spaces, attics, or lofts
  • Behind shutters or window frames
  • In wall cavities or holes in walls
  • In sheds, garages, or other outbuildings
  • Underneath decks or porches
  • In bushes, shrubs, or trees

It’s important to regularly check these areas for signs of nesting activity, particularly during the warmer months when wasps are most active.

Increased Wasp Activity

Another clear sign of an infestation is an increase in wasp activity around your property. If you notice more wasps than usual flying around your garden or home, this could indicate that there is a nest nearby.

Pay attention to where these wasps are flying to and from – they may be leading you back to their nest. It’s important not to disturb the nest, as this can provoke the wasps and cause them to become aggressive. Instead, observe from a safe distance and consider calling a professional pest control service if you believe you have a wasp infestation.

Buzzing Sounds

Wasps can create a buzzing sound when they are flying or crawling around their nests. If you hear buzzing sounds coming from your walls, roof, or other areas of your property, this could be a sign that there is a nest hidden away.

It’s important not to attempt to locate the nest by tapping on walls or disturbing the area where you hear the buzzing. Doing so could cause the wasps to become agitated and potentially sting.

Finding Dead Wasps

If you start finding dead wasps around your home or garden, this could be an indication that there is a nest nearby. Wasps die naturally over time, but an increase in dead wasps could mean that their population is growing rapidly.

Keep an eye out for dead wasps both inside and outside your property, and be sure to check for nests in the areas where you find them.

Preventing Wasp Infestations

Prevention is always better than cure when it comes to dealing with wasp infestations. Here are some tips to help you prevent wasps from taking up residence in your home or garden:

  • Keep your property clean and tidy: Wasps are often attracted to food sources such as open garbage cans, compost bins, and fallen fruit in gardens. Make sure you keep these areas clean and secure to avoid attracting wasps.

  • Seal entry points: Check your property for any gaps, cracks, or holes that could provide access for wasps to enter and build their nests. Make sure to seal any openings you find.

  • Regularly inspect your property: As mentioned earlier, regularly check common nesting areas for signs of wasp activity. This will help you identify any potential infestations early on.

  • Use wasp-repellent plants: Planting certain plants in your garden can help deter wasps. These include wormwood, eucalyptus, mint, and marigolds. Keep in mind that some of these plants may also have an effect on other insects or wildlife, so be sure to research the best options for your garden’s ecosystem.

Dealing with Wasp Infestations

If you discover a wasp infestation on your property, it’s important to deal with it as soon as possible. The longer a nest is allowed to grow, the more difficult and dangerous it will be to remove.

In most cases, it’s recommended to call a professional pest control service to handle the removal of wasp nests. They have the necessary experience, equipment, and protective gear to safely and effectively remove nests without putting you or your family at risk.

Remember that tackling a wasp infestation yourself can be dangerous, particularly if you are allergic to wasp stings or are unsure of how to properly handle the situation. When in doubt, always seek professional assistance.
