Masonry and Mining Bees

Friday, May 18th, 2012

In spring and early summer, you may notice bees coming and going from holes in walls or the ground. These are probably masonry bees (also called mortar bees) or mining bees. They resemble honeybees, but they don’t produce honey or beeswax. They are solitary bees, but don’t be confused by that term. “Solitary” in this context means each female is fertile and will build her own nest, collect her own food, and lay her own eggs. Many of these types of bees may live near each other, but the difference is that these bees do not live in a hive, they don’t swarm, and they generally don’t sting. They are non-agressive. Males have no stinger, and females will usually only sting if handled roughly. These bees, being very good pollinators, are helpful to have around.

The general life cycle of these bees is that larvae from the previous year, which have overwintered in the nest, will pupate and emerge as adults, usually in the spring. The males generally emerge first and wait for the females so they can mate as soon as the females emerge. The males die after mating, and the females begin building their nest and preparing a food source for the eggs they will lay. Some of the eggs will be fertile, and will develop into female bees; the others will be infertile and will develop into male bees. In preparation for egg-laying, females will make several pollen-gathering trips, and this is when you are likely to see them. They’re generally only active for a few weeks every year while they’re gathering pollen and nectar. After laying their eggs, the females die. The eggs hatch into larvae and the cycle begins anew.

Masonry bees will nest in holes in the ground as well as in existing holes in soft stones or bricks and loose mortar, with a preference for south-facing locations. They may enlarge these holes slightly, which can sometimes cause structural damage to buildings, but normally the holes aren’t very deep.

Female masonry bees fill the holes with nectar and pollen before laying an egg in it and sealing it. These bees nest in spring and summer, laying anywhere from 2 up to as many as 12 eggs in sealed cells, depending on space available in the hole. When the eggs hatch, the larvae will feed on the stored pollen and nectar and remain in the cell over the winter. They pupate in spring and emerge as adult bees in the summer.

There are approximately 20 species of masonry bees in UK, with the Red Mason bee being the most common.

Mining bees nest in the ground in loose soil and are commonly seen in lawns. There are many different species in the UK. One of the most frequently-noticed is the Tawny mining bee, which stands out thanks to its furry, reddish-brown body.

Mining bee nests usually look like a volcano-shaped mound with a hole in the centre about the size of a pencil. Sometimes these are built in lawns, and sometimes under stones and pathways. Some mining bees prefer to nest in sandy, south-facing ground, while others like clay more than sand. The bees build tunnels under the mound, and depending on the bees, tunnels can be as deep as half a meter. Eggs are laid in compartments off the main tunnels.

There may be several mounds in an area, or sometimes mining bees will even share an entrance, but this is not indicative of a colony, as each female has her own tunnel. Like masonry bees, the females collect nectar and pollen to provide a food source for the eggs they will lay inside their nest.

Mining bee nests won’t harm gardens and the mounds soon disappear, as most species of mining bees are only active for a month or so in the Spring. Their larvae remain underground for the rest of the year and will emerge as adults the following spring,

Control of masonry and mining bees is usually not necessary. However, if masonry bees are causing structural problems, the best time to carry out control is in late autumn, when the females are no longer around. Then the holes can be filled so they won’t be reused the following spring.

Beetle Pest Identification

Tuesday, November 30th, 2010

carpet beetleWhen we mention the word Beetles we automatically think of the Fab Four from Liverpool or the iconic Volkswagen car. However, if you are a keen gardener or a farmer, then the mention of this word can spell disaster. There are over 4,000 different types of Beetles that are common to living in Britain. Although some of these Beetle species have not been seen in over 30 years and others are fast becoming instinct. Of the Beetles that are left, they are a busy bunch and can be found doing everything from burying the bodies of animals to pollinating flowers, as well as destroying crops and turning your ornamental garden into a pile of dead plants.

One of the Beetles that gardeners have to watch out for is the Lily Beetle. These were once only found in a handful of places in the warmer South East, now, due to the warmer winters they have been found as far up as Cumbria. These beetles are Scarlet in colour and can measure between 6 and 8mm long and have black heads. Between April and September the Beetles lay eggs on the undersides of leaves then after one week they hatch into reddish-brown maggot-like grubs. A colony of beetles and grubs can strip the plant of its flowers and leaves, weakening the plant and possibly killing it.

Yes, Pigeons Are Pests Too!

Wednesday, November 10th, 2010

pigeons are pestsAs our towns and cities grow to cope with the demand for housing, shopping centres and business parks the wooded and green areas that they are built on is often the home to numerous wild animals. One of these which is now thriving in nearly every one of our major towns and cities is the feral pigeon. These birds have now adapted so well to our tows and cities that they are now considered pests by many councils. Pigeons can now be found nesting on balconies, rafters of old buildings, chimney pots and even on the roofs of shops and market stalls.

These pigeon pests can often been seen looking for scraps of food that people fling down. They’ll tear open bin bags that contain food and even steal out of your hands if you’re not careful. Apart from the birds scavenging for their food one of the worst sights has to be the pigeon dung, which is not only unsightly but can cause several serious health effects, since they carry more than 60 associated diseases such as salmonella, toxicosis, and inflammation of the alveoli in the lungs. Pigeons are also known to carry parasites such as ticks, fleas, and lice.

Cockroaches The Restaurants Nemesis

Wednesday, November 3rd, 2010

cockroach pest controlAs an owner of a restaurant, bistro, cafĂ© or even the local fish and chip shop, one of the worst and most disturbing sights has to be that of the cockroach scurrying under your cooker, fridge or units. These pests epitomise dirt, filth and rubbish and anyone that sees them will automatically think that your premises has poor hygiene, and, in today’s health and safety culture that could be enough to lose customers and inevitably cause your business to close down.

Cockroaches are known to be among the hardiest insects on the planet, with some species being capable of remaining active for a month without food. Cockroaches can survive in extreme conditions such as heat and cold and some have been know to survive after being submerged in water for over thirty minutes. There are known to be over 4000 different species although in Britain only about four are known as pests.

Fleas The Invisible Family Pet

Friday, October 29th, 2010

cat fleaWe are known as a nation of pet lovers with many households having either a cat, a dog or some other pet sharing their home. One of the problems that many pets have is fleas! These wingless, parasitic animals often survive by sucking the blood of their host, in many instances your pet will suffer in silence. Fleas have mouth parts which are adapted to suck blood. However, one of the most distinct characteristic of an adult flea is the adaptation of their back legs into very muscular organs, which are now capable of projecting these parasites considerable distances.

There are three main types of fleas which are common to our homes: the cat flea; the dog flea; and the human flea. The cat flea is by far the most common to be found in our homes and although they require the blood of the cat to lay it’s eggs, it is not adverse to feeding off human blood. Cat Flea bites will cause a characteristic dark red spots around the area which remain irritated for one or two days. More worrying is that unfed fleas can survive for up to four months lying dormant in your home until the vibrations of the host make them active.

Living With ‘Roland’ The Rat

Wednesday, October 27th, 2010

rats the non-friendly typeDuring the 1980′s we were introduced to Roland the Rat, this puppet was loveable, cuddly and very cheeky… Roland also had several records in the pop charts and, most notably, this puppet single handedly saved the sinking morning television program TV-AM. By the end of the 80′s, nearly every household in the UK owned a piece of ‘Roland The Rat’ merchandise.

Decades later, Roland might be a distant memory but we humans are still never that far away from a living version of which ‘Roland the Rat’ was styled on. This is a disturbing fact and one which can cause many people to shudder with fear.
