Wasps vs Bees – How to Identify Them Before Arranging Pest Control in Pale Green

The small openings in a house, from airbricks to chimney pots, are where insects get in, and watching them tells you what has moved in.

Small openings, big colonies

Houses are full of small openings that were put there for good reasons: airbricks to ventilate floors, vents to let out steam, gaps around pipes, the chimney stack, the eaves. To a nesting insect, they are doorways to a dry, warm cavity.

A nest behind an airbrick or inside a chimney breast can reach a significant size before anyone notices. The first sign is often a stream of insects at one point.

Checking these openings from the outside is a simple, safe way of finding out what is happening.

Many of these openings were never designed with insects in mind, which is why they are so easy for nesting wasps to use. A little knowledge of where they are on your house helps you check them quickly.

A little patience pays off here. Spend ten minutes at each side of the house on a warm afternoon, standing well back with a cup of tea, and you will learn more than from any amount of poking around. Most openings turn out to be quiet. The one that is not stands out immediately.

Airbricks and wall vents

Airbricks sit low on the wall and lead to the space beneath the floor, or into cavities. Wasps sometimes use them. You may see slim, striped insects going in and out of the small holes, and a bare patch of brick around them.

Bumblebees occasionally use low entrances, and honeybees prefer higher ones. Check the shape of the insects, not just the position.

Do not block an airbrick, even temporarily. They exist to ventilate, and a blocked one traps insects in the cavity.

Be careful with cavity walls. A nest in the cavity can be large without any sign from outside except a small stream of insects at a single hole. By August it may hold from 2,000 to 10,000 wasps or more, so a modest entrance should not reassure you.

Water stains or damp patches near airbricks are not necessarily connected with insects, but a combination of damp and insect traffic is worth mentioning. Take a photograph of both.

Chimneys and flues

An unused chimney is a tempting site. A chimney pot, a stack or a cowl can hold a wasp nest, and a chimney breast can hide a honeybee colony. Insects may emerge in a stream from the top, or find their way down into the fireplace.

If insects appear in a room through a fireplace, close the room door and keep clear. Do not light a fire to drive them out.

Look at the stack from the ground, with a zoom if possible. A steady line of insects at the top is a good indicator.

Listen from the room below the chimney breast on a warm day, but do not press against the wall. A dry rustle or scratching suggests wasps, and a steady hum suggests honeybees. If you hear either, note it and mention it when you ring.

Birds sometimes nest in chimney pots and vents too, and nest material can be mistaken for insect activity. If you see twigs and grass rather than grey paper, and birds rather than insects, you have a different issue entirely. Watching the traffic for a few minutes quickly settles it.

Eaves, soffits and gaps

Soffits and fascias are favourite wasp entrances. A small gap beneath the roof edge opens into a void that runs along the whole house. Gaps around pipes, cables and extractor outlets are similar.

Bees favour fewer, larger cavities, and tend to settle in those that are quiet and enclosed.

Check at different times of day, and make a sketch of the busiest points. Do not climb a ladder to look closer, and never fill a hole.

Satellite dish brackets, cable entry points and extractor fan housings are further gaps worth a glance. Any hole big enough for a pencil is big enough for a wasp. A walk round the outside every few weeks in spring and summer catches most problems early.

Looking after yourself while you watch

Choose a spot well away from the openings, and avoid standing beneath them. Keep children and pets indoors or away. If insects are coming into the house, keep windows closed on that side.

After a sting, wash the skin, flick out a sting you can see and hold something cold on it; call 999 for swelling of the face, lips or throat, wheezing or difficulty breathing, dizziness or a widespread rash.

Do not poke or tap the vent, the airbrick or the chimney. Allergic households should check with their GP, and tell us at booking so that we can prioritise the appointment.

Resist the urge to look inside. Shining a torch into an airbrick or peering into a fireplace can bring a defensive response, and a dislodged nest in a chimney can bring insects into the room. Wait for the technician.

Booking

If your observations point to wasps, Get in touch on 01245 327274, or use the online booking form on the contact page. One nest is a flat £90 with one visit guaranteed, with £35 per nest for any more at the same address.

Visits run seven days a week; same-day service is offered for domestic and commercial jobs, all fully insured.

In Pale Green and the surrounding area, the technician can visit once the booking is made. If the insects are honeybees or bumblebees, contact a local beekeeper or bee organisation instead.

Mention any known routes into the house, such as a disused fireplace or a gap in a floor, when you book. It helps the technician anticipate where insects may emerge, and where to look.
