Lots of wasps but no nest. Starting in the fall, you might notice swarms of wasps around your house.
However, these wasps do not have nests or young ones to feed and protect like other wasps. So what’s the reason for this? Do these types of wasps pose any threat to you?
Let’s find out further below.
Lots Of Wasps But No Nest
There are three common ways that wasps can enter your home. One or more wasp nests are built either inside or near openings that lead inside the house.
For example, a wasp nest may be located under or behind a window screen with a tear or near an open door that isn’t weatherized or beyond repair.
1. Install Screens On The Large Vents
Screens or shields placed on vents found on rooftops and chimneys can help protect a house from wasps. After mating, the females seek entry points into your house to prepare for winter hibernation.
You don’t want those wasps in your home, not just because they’re unpleasant but also because their presence portends infestation by rodents that scurry into attics and other hiding places to evade the cold of winter.
It is wise to invest in such screening systems for roof vents and around pets’ outdoor shelters where wasps are common — to stave off both types of unwanted insects from making it inside your home.
2. Seal Gaps and Cracks
While wasps can be alarming, they’re not often aggressive creatures. It’s best to know what steps you can take before an encounter to protect yourself from getting stung.
Keep wasp nests away from your home by keeping grass short and removing trees nearby that catch debris like leaves or other debris that might fall into a nest.
Seal crevices around windows and doors with quality caulk. Install door sweeps and window screens on the inside of the frames of doors leading outside and any windows that remain open for long periods.
You can also install shields over some windowsills if necessary.
3. Use smells that repel wasps
Some scents can repel wasps. Using essential oils of these scents in a mixture with water, you can make a spray that will help keep paper wasps, yellow jackets, hornets, bee species and honeybees away from your home.
Spraying these smells in the fall months helps deter wasps from making nests inside your house because they tend to live somewhere warm all year round.
Peppermint oil is the most widely used for this purpose; there are many products available for use, including liquid form, sprays, gels or candles, and electronic plug-ins and aerosol cans.
It’s recommended that you use any of these deterrents both indoors and outdoors to prevent wasps from getting inside.
4. Use wasp spray on wasps that have gotten into your house
If a nest is causing damage to your home, you can find sprays designed to kill that species of wasps. When using wasp insecticides, read the directions and do as instructed.
If a nest is hanging from an entry or exit point, it is best to carefully set up traps and knock them down with a broom since spraying will only cause the wasps and queens to scatter around your house.
After using wasp sprays or killing any wasps, it’s important not to leave their bodies for other pests like ants or cockroaches that may eat them.
Make sure you remove any corpses before they might attract such unwanted insects.
5. Set up wasp traps
Use wasp traps to entrap any wasps, hornets, or bees on your property. You can use the traps both indoors and outdoors.
These traps lure the pests with a food source. The bait inside the trap will attract wasps making entering the trap easy.
Once they’re inside, it will lock to keep them secure so that you can dispose of them away from your home, where it poses no risk.
Why There Is No Nest Around Yet There Are Lots Of Wasps?
Paper wasp swarms are a common sign of mating behaviour. It usually occurs in the fall months as soon as September to October.
Wasps gather in high areas to mate and build a nest for the winter. They will choose tall structures around your house, like roof peaks and eaves, or even transmission towers or other tall buildings so that they don’t get stepped on by people or animals.
Nobody knows why paper wasps nest in these places. Still, it is theorized that their choice of nesting sites could be influenced by electromagnetic fields generated from electrical equipment nearby, such as power lines and transformers.
In addition to this, researchers also say that if there’s ever an absence of insect prey, paper wasps prefer to move onto places where most insects aren’t found instead of moving into wooded areas.
You’re not at any risk, though, because they go away after mating season since they do not live close to humans anyway.
Is there anything wasps do when their hibernation is over?
During the spring, female wasps come out of their hibernation. They immediately get straight to work for building nests and laying eggs.
A single female wasp can start a colony, but multiple wasps from different families can build their nests together. If there are wasps inside the house, they’ll usually build their nests where they’ve hibernated.
So if you see wasps building nests on or in your home or garage, it may shed some light on a potential nesting place outdoors.
Once the nest is built and established, these hard-working little critters will demand attention and respect as they guard their valuable treasure – what are now your family’s favourite baking ingredients!
Don’t let this delicious but deadly combination of virtual stings put a damper on the seriousness of an ever-growing problem that many homeowners are facing today with increased frequency while seeking nonsynthetic methods of pest abatement.
Remember that while wasps are not as aggressive as hornets, they can still sting. Wasp stings can cause pain, swelling, and itching. The best course of action if you have a lot of wasps near your property or have spotted multiple paper wasps’ nests around is to call a pest control company for help. Taking matters into your own hands when dealing with wasps is risky as multiple stings could occur throughout the removal process.
