Wasps flying around roof and downspouts

wasps flying around roof and downspouts

i have several wasps flying around my roof and downspouts each day but i don`t see a nest?

This is no surprise. In general, wasps will find these places attractive any time of year. As explained in our WASP CONTROL ARTICLE, they like sheltered spaces and voids for nest building so the sides of homes, up under soffits and roof lines, are perfect locations for them to live. But there are many homeowners who never see them during the summer and then in the fall they start to appear. So why only then?

Well, in the fall, many species of wasps are getting ready to overwinter or hibernate. As our article explains, they’ll crawl up into small cracks and crevices most any home has along shingle lines, around window frames and where soffits, gutters and downspouts meet. In these cases the homes don’t have nests; the wasps are simply foraging there to hibernate. And though most of these wasps will stay on the outside of the structure burrowing only deep enough to be protected through the winter, it’s quite common to have some go so far into the home they end up in living spaces. If left untreated, these homes will attract more and more wasps over the years and eventually there will be nesting as well as periodic activity inside during the winter.

To stop this behavior, there are two things you can do. The first is to dust with DRIONE. I use it around my home twice a year; once in the spring (to stop new nests from forming) and once in the fall (to stop invading perimeter pests from hibernating on my house). As our article explains, Drione lasts a long time and is highly repellent to any insect. It’s smokey like design enables it to filter up and into all routes of entry around treatment points making it highly effective when used around any structure. I find it’s all I need to do at these crucial entry points but for some people, a topical treatment is needed as well. For that the CYPERMETHRIN is well suited. After dusting with Drione, spraying these same areas with Cypermethrin should be considered if you still see them around. Fast acting and highly repellent to wasps, it will last up to a month and can be applied to any side of the home where you see activity.

Wasp Infestations

Wasp infestations, whether outdoors or indoors, are best handled by your pest management professional, someone who has the experience, equipment and products to safely, effectively and efficiently resolve the concerns. So, whenever wasps are a problem, contact your pest management professional and request an inspection and a plan for dealing with the issue.

How Do Wasps Get Into the House?

Generally, wasps get in through openings that lead inside our homes and commercial buildings. Therefore, effectively sealing openings that may lead into a home is critical for wasp prevention. In addition, sealing access points inside your home will help prevent problems from many other pest insects and spiders.

Why Do They Come In?

Wasps come inside because they are looking for:

• a protected place to overwinter (hibernate)

• accident or happenstance

Generally, wasps come inside our homes as the result of three primary conditions and situations.

1. One or more wasp nests are built either inside or near openings that lead inside the house. For example, a wasp nest might be located near a window with a damaged screen or a door that is left open to the outside. Since wasps sometimes construct their nests in wall voids and attic spaces, wasps from those nests may get inside our home’s living spaces. One of the more frequent causes of this occurrence is when a homeowner sees wasps going into and out of a void. The homeowner may seal up that entry and exit before all of the wasps in that nest are dead. The result may become a whole nest of wasps that can no longer get outside and begin to chew through the wallboard or ceiling, resulting in a angry, confused wasps that are now inside the house.

2. Wasps that seek protected, interior spaces in which to overwinter. Many wasp species have a lifecycle that depends on fertile queens from the colony finding a protected site in which to survive the winter. Most of the time these queens choose sites other than inside our homes to overwinter. They also find our attics or other protected sites inside the home to be very cozy. Once the female wasp is settled in, they usually are not seen flying around inside the home. However, until they find the right overwintering site and then again in the spring when they want to get outdoors and begin their new nest, they can be troublesome and alarming.

3. Wasps that get inside by happenstance such as entering through an open door or window or become “hitchhikers” who are accidentally brought inside. Wasps are constantly seeking new sources of food for their nest mates. Therefore, it is not surprising that wasps would investigate the inside of homes if they can readily get inside the home. In addition, while it does not happen too often, wasps can unintentionally get inside if they “hitch a ride” on just about anything we might bring inside our homes and not notice the hitchhiking wasp.

What Problems Do They Cause?

The answer to this question depends on why the wasp got inside.

• If a wasp nest is built inside, the resulting problem is an infestation that may become a serious stinging episode and perhaps an associated allergic reaction problem. Also, wasps that nest inside may damage the wallboard or ceiling. Another major problem associated with inside nests is the possibility of scavenger pests that infest abandoned inside wasp nests.

• If a wasp gets inside to overwinter, it is very likely that it won’t even be seen until the following spring when it decides to get outside and start a new nest. Even then, those wasps are not very aggressive and not likely to sting unless threatened.

Could Wasps Inside Lead To An Infestation?

Yes, if the wasps that get inside build a nest that is also inside, and the activities of that nest bring them into contact with the people who live there. Otherwise, overwintering wasps and those that get inside by “hitchhiking” will not become an infestation.

Where do wasps go in the winter?

The weather will begin to warm up soon, but if you haven’t spotted a wasp yet, that begs the question – where do wasps go in winter? Are they still in their nests, keeping warm and cozy like honey bees in a hive or have they migrated south with birds in search of food, sunshine, sandy beaches and sticky, sweet cocktails? And even more importantly, when will the wasps be back? We’ll answer these questions here.

Wasps are one of the last things your property needs and these stinging insects never fail to bring on stress and anxiety. So if you start seeing wasps flying around your home or business as the weather warms, call Ehrlich at 888-984-0186 or contact us online.

What do wasps do in the winter?

As winter starts drawing to a close, you may wonder: How do wasps survive the winter? Well, actually, many of them don’t. When the first frost comes, most of the wasps in the colony die except for female wasps that are going to become queen wasps. You might be happy to learn that’s the case, but should you be concerned about random wasps in winter that do pop up at your home or business?

First, let’s highlight a couple of wasps you should be aware of:

  • Yellow jackets – They have yellow and black abdomens. Queen yellow jackets are roughly ¾ inches in length.
  • Paper wasps – They tend to be brownish in color, with yellow marks. Paper wasp adults are about ⅝ to ¾ inches in length.

During winter, these wasps hide in undisturbed locations such as attics. If warm weather crops up during the winter, you may see a wasp in your home, such as a paper wasp creeping on the floor. In instances like this, don’t get too worried about it being a life or death situation. Still, be wary that a wasp might create a nest on your property when it becomes warmer and you should stay alert.

What do wasps do in spring?

On the positive side, spring will be here soon, but that also means you may begin to spot queen wasps emerging from their overwintering place, which could be as diverse as the warm folds of a curtain, a cozy crevice in a shed or a loft. The queen wasps will be on the scout for a new place to build a nest and lay their eggs.

Yellow jacket nests may be found in the ground or affixed to bushes or shrubs, and paper wasps nests are located in places such as under window sills. Paper wasp colonies will typically grow to be the biggest during late summer or the early fall. You’ll certainly know it’s a female if it stings you because only the female wasps have the distinctive stinger, which they can use repeatedly, unlike bees.

Later, worker wasps return to the nest and die. Typically only females that have mated survive. The queen does not usually use the old nest and builds a new wasp nest, creating a single cell at the end of a petiole. Six more cells are then added to create the hexagonal shape.

The queen then lays eggs that grow into small larva. The larva grows to full size, then it pupates into an adult worker wasp. The life cycle from egg to fully grown insect is approximately three weeks.

What’s inside a wasp’s nest?

The worker wasps will continue to build and maintain the nest, forage for food and feed the larvae. Until June the nests will normally be golf ball sized but may be larger with warm weather. From late June the wasp nest will have grown considerably and wasps can normally be spotted on the outside carrying out repair and maintenance work. Take a look at this footage by worldofwasps showing hornets at the nest.

Wasps in House

Wasps usually become a problem inside a house when their nest is located outside nearby. Some wasps enter a house in the fall, hibernate undetected through the winter, and then drowsily emerge in the spring. In rare cases, wasps may actually build their nests inside of a house, especially if there is an entry via a ripped window screen, a gap in doorframes or windowsills, or an opening to the attic. Some wasps do not sting, so identifying the type of wasp in your house gives a better idea of how to handle these intruders.

Though the wasps that have entered your home may eventually die off, they pose a stinging threat. Also, if an outdoor nest goes untreated, the wasps will continue to build the nest to greater proportions and raise more of their young. In some cases, the nest will grow to a size of several hundred wasps by the end of summer. More wasps may enter your house and more stinging incidences may occur, especially if the nest is located in a high-traffic area.

Exterminate the wasps inside of your house with a swift fly swatter or broom. Then determine the source of the wasps. Locate any nearby nest and be especially wary of nests located on the eaves of the house or near doorways or windows. Wear several layers of clothing and goggles for additional protection as you spray the nest with insecticide or spray adhesive. Spraying the nest is most effective at night when the majority of wasps are in or on the nest. Be sure to stand away from the nest as you spray, not directly underneath, to decrease your chances of getting stung. Abandon the nest for several hours before returning to scrape the nest off. If there are hibernating wasps inside your house, enlist the help of a professional to drill holes into walls, to insert insecticide dust to kill the wasps.

Wasps Indoors in Winter! What Gives?

By Chris Williams on March 8, 2011.

Q. I found a wasp in an upstairs bedroom yesterday, flying around indoors in the middle of winter! It was mostly black with some yellow stripes and long legs. I thought it was a one time thing but today I found another one in a bathroom window. What’s going on? Do they have a nest inside?

A. No nest, you just have some temporary winter guests. At least you’re entertaining royalty! These are no doubt future paper wasp queens. Other wasps sometimes spend the winter indoors, but paper wasps are notorious for ending up inside. They’re the wasps that make those open-comb nests outside that look like an upside-down umbrella. In fact, they’re sometimes called umbrella wasps.

In late summer or early fall, the paper wasps in a nest begin to die except for newly mated females who are destined to be next year’s queens. When the weather cools, their internal clock tells these future queens that it’s time to find a protected place to wait out the winter. Usually that’s outside under bark, or logs, or even under siding or shingles. But if they can find an opening into a nice, warm attic, they’ll take it!

Most people don’t even notice the gradual migration of the wasps inside (although sometimes you see them hanging around outside looking longingly at your doors and windows!). Because paper wasps fly, they are able to enter through openings near the roof line and often end up in attics. They also hide in wall voids, behind baseboards, behind draperies, under carpet edges, and in various cracks and crevices.

Paper wasps don’t move around much once they’ve settled in and you usually won’t even know they’re there – until the first warm days of spring or (as you’ve discovered!), sometimes during a warm spell in the winter. Then the wasps become active again and start looking for a way to get back outside. They’re attracted to light at windows. They are usually sluggish as they crawl and fly about inside and can be easily caught, or squashed, or vacuumed. They’re not aggressive but remember that they are still capable of stinging if handled!

If you have a large population of overwintering wasps in an attic or in wall or ceiling voids, you may need to have a professional treat those areas. Next year, consider an outside preventive treatment in early fall to help keep them from moving in. Also caulk or seal openings around roof eaves, utility line entrances, or other sites where wasps may be entering your home.

When do wasps die at the end of summer and what do they do over winter?

Share this with

Wasps, like many of us, much prefer the summer months to the winter, but unfortunately for them, winter doesn’t just mean putting on an extra jumper, it means almost certain death!

As we move into autumn, the UK’s wasp population starts to reduce dramatically with the vast majority of them perishing during the coldest weeks of the year.

There is not a set date that wasps meet their maker, but it happens when the weather turns cold and they simply die from a lack of food.

Wasps feed on nectar, but also on other insects and fallen fruit, none of which is plentiful over the winter in the UK, so they die as a result.

With temperatures higher than usual over summer this year, it could be a bit later that wasps suffer their demise, but it tends to be around late September that people are starting to get sick of them.

Whenever we hit our next spell of cold weather we will see a sharp drop in wasp numbers, but it can be well into winter before they really disappear as temperatures can need to reach zero for them to fully run out of food.

The males die over winter whilst queen wasps hibernate, but a large percentage of them die as well as they are eaten by other insects, mainly spiders.

The queens can also struggle if it is a mild winter as they can emerge from hibernation too early and not have enough food available.

It’s tough being a wasp!

They are also more important than many realise. Unlike bees, wasps are carnivorous, meaning that they not only work as excellent plant pollinators but they also eat aphids – giving plants a decent chance at flourishing.

Wasps start life in spring when a lone queen lays a few eggs and then looks after them until they hatch into sterile females or workers.

These will then help the queen tend to the next batch of eggs, feeding and increasing the size of the nest.

By July, the queen will have produced enough workers to take over all maintenance of the nest and feeding responsibilities.

At this point some of the last eggs to hatch will become male drones and fertile females – or new queens. These will leave the nest and mate with other male and female wasps around autumn time.

While all the other wasps die off as winter approaches (as well as the old queen), the new queens will hibernate over the winter until the following spring. The original nest will become deserted at this point.

How to Get Rid of Wasps in Roof Vents

Things You’ll Need

Wasps cause problems when they build nests in or around your home. They will defend their territory and get aggressive if you get too close to a nest or try to disturb them. Roof vents are attractive to wasps because the vents are covered and therefore offer protection. If wasps aren’t dealt with as soon as they start nesting, an infestation becomes a greater risk. Getting rid of wasps in roof vents requires diligence to make sure they don’t return.

Step 1

Spray an insecticide into the vent to kill any wasps that are currently in the vent. Wear a breathing mask and follow all instructions on the package to prevent inhalation. Spray at dusk when the wasps are more likely to be dormant inside the nest.

Step 2

Cover the vents with plastic bags for several days to prevent more wasps from going into the system.

Step 3

Check your attic for openings that the wasps could be using to get into the vents. Breaks in the insulation or small holes in the wood are common sources for wasp entry. Any breaches require sealing to prevent more wasps from entering. Wear long-sleeved shirts and long pants to help protect against stings.

Step 4

Call a professional if the wasp problems continue because stings could be dangerous, especially if you’re allergic to them.
