…be found especially near flowers, but you can tell the difference between wasps and wasp beetles. Appearance A wasp beetle is also called a clytus arietis. They belong to the longhorn beetle family, which is also called cerambycidae. The wasp beetle can be recognized by its distinctive and sharp appearance. The wasp beetle can also be recognized by its black and yellow stripes that run across its elongated body. Similar to the animal it tries to…

…. There is a sting on the back of the body, and it is with this sting that wasps stick. Although wasps are considered to be very aggressive, they only sting as a last resort. Wasps are relatively small animals. The larger wasp vespa crabro grows to a maximum of 2.5 cm long, but the typical size for smaller species is 1.2 to 1.4 cm. The worker wasps are typically between 11-15 mm long. The queen is somewhat larger and can grow between 14-19 mm long…

…d wood preservatives as these agents have little effect on this species. You can however use heat treatment for control. The wood must be heated up to 75 degrees for minimum eight hours or dried, so the humidity drops below 14%. Treated wood will never be attacked by wood wasp larvae. Wood wasps does have a negative impact on forestry, which is why there are import restrictions of conifers in Australia, to avid infested wood. The export of conifer…

…males from the larger parasitic wasp species, choose to parasitize on wood wasp larvae or butterfly larvae. Damage There are no parasitic wasp species that can damage furniture or houses. In fact, a variety of the species are used for biological pest control on farms, in plantations, gardens and greenhouses. Some species can sting with the laying brood, but this rarely happens. If this happens, it is usually because you accidentally squeeze them….

…nd other dry goods, depending on where their eggs have been laid. Then the larvae begin to spin silk threads. The flour moth larvae have a sticky web. It is this web that creates difficulties for the industry. The larva’s sticky silk attracts flour, dust, and the larva’s own excrement. This can give small pockets of extremely unsightly odor and contaminated flour. Both adult flour moth and their larvae will try to create a dark habitat or search f…

…The larva of a fur beetle is unique in their appearance compared to other larvae. A typical larva is an elongated little creature that is white, yellowish, or beige. But a fur beetle larva has a brown color and is hairy. In the end, it has a hair-brush, which makes it easy to recognize, size wise they are up to 1 cm long. One can take the ordinary fur- or carpet beetle larvae as a brown carpet beetle larva, as they are related. The easiest way to…

…time, but in the short time it can be a great inconvenience to humans. The larva, also known as mealworm, can cause great trouble to humans, which is the reason why this beetle is considered a pest. Appearance The fully grown mealworm beetle is relatively large; between 12 and 18 mm long. Color wise they can vary from dark brown to completely black. Mealworm beetles have a flat shape, and they have a long and wrinkled hind body. Their front body i…

…it is a larva, it will be gray, brown, white and look like other butterfly larvae. Butterfly larvae have a main capsule, legs and what are called wart feet. Biology and behavior As mentioned, this larva is often found on or under different roofs, which gave it the name “roof worm”. It will typically be thatched roofs of straw. The reason why it is found here is that the “roof worm” lives on grass and hay and is therefore brought to the house with…

…nature of the wood, the type of wood, humidity, and temperature. Once the larva has undergone its development, it will begin to pupate. This often happens in the month of July or August. After a few weeks in this condition, the larva is transformed into an adult deathwatch beetle. However, it does not move from its nest immediately, but stays inside the tree until the following spring, after which it gnaws out of the tree. The tree bears visible…

…e the small, hatched larvae can feed on the surrounding material. Here the larvae have every opportunity to develop. The small larvae spin their own whitish cocoon in which they pupate. The cocoon has an almost tissue-paper-like appearance, and the webs of the larva can be seen as thin threads and spun cocoons in the infested area. The development from larva to fully adult thief beetle lasts about 3 to 4 months if the larva has good conditions e.g…

…o eat as well as a steady temperature around 25 degrees. Both clothes moth larvae an fur moth larvae spin sticky threads, which protect the individual larva from drying out. This sticky web also helps to create a ‘tail’ of excrement, remnants of food and dirt. The larvae of the cloth moth move around whit this web is glued to the surface. The fur larva drags its web behind it in a tubular shape. Damage You know if you have moths in your textiles i…

…rs long and has drawings as well as dark spots on its light gray skin. The great gray slug is larger with a body length of 15 centimeters. This species is also grayish, but it is often seen with a reddish tone. Here the hind body has dark longitudinal stripes, while the front body is marbled. Biology and behavior Both the cellar slug and the great grey slug can be found near or in houses, shacks, basements, and the like. They are primarily nocturn…

…ere is little doubt if you have had a visit from Dermestes haemorrhoidalis larvae in the woodwork. The passages that the larvae gnaw appear as about two centimeters deep and circular passages that have a diameter of three to four millimeters. They can therefore cause great damage and even weaken the woodwork. Prevention and pest control A single beetle now and then hardly poses the big problem, as it is most often a single beetle that has strayed…

…es or tunnels, which is otherwise the custom for most of the tree-drilling larvae. Their development from larva to adult wharf borer beetle lasts between 1 to 3 years, depending on the conditions in the tree. Damage There is no doubt that wharf borer beetles can do great damage if they attack in the wrong places. It can for instance be an extremely difficult task if the beetles attack basements in houses located on framed wooden poles (piloting)….

…les like temperature, humidity and the quality and nature of the wood. The larva will usually be fully grown after two or three years. Once the larva is fully developed, it will pupate, which happens in the fall, and within a few weeks, the pupa will have developed into an adult beetle. However, the beetle will remain inside the tree until May-June, and then it will emerge from the tree, through a characteristic fly hole of a diameter of 2-3 mm. T…

…ing dust, which consists of the undigested parts of bark and wood from the larvae’s excrement. The larval development normally takes about 2 years. The adult larva pupates in an L-shaped passage of 2-3 centimeters, which it gnaws itself. Once the larva has gone through the process from larva to adult tanbark borer, it goes back through the pupae. It then gnaws its way through the bark of the tree, leaving an oval fly hole with smooth edges of abou…

…40 micrometers and the internal channel is only 5-10 micrometers wide. The larva feeds on lymphatic and dissolved tissue through the stylostome. At the same time, the stylostome functions as an anchor to harvest mite larvae. The identification is ensured by placing the mites found on a microscope slide with a drop of Hoyer’s Medium for further examination in microscopes of high magnification. The animals can be easily be caught on a piece of adhes…

…for the first 2 to 10 days of its life. When it has finished its meal, the larva hides in hiding in a crack or crack no more than a few meters from the nest, where it moves to change skin. The larva goes through several stages – where it alternately seeks out its meals on the pigeon and seeks shelter to change skin – until it is finally fully developed as either a sexually mature male or female. If the larva ends up as a male, it only has to worry…

…alworm beetle, it is most likely a Destructive flour beetle. Likewise, the larva of the Destructive flour beetle can at times be mistaken with the larva of the mealworm beetle flour beetle, which is commonly called a mealworm. This is probably because the two species both belong to the same family, namely shadow beetles, also called Tenebrionidae. Biology and behavior Destructive flour beetle can become surprisingly old, in fact over three years….

…ized by its lively behavior. Since the flour beetle is an insect, it has a larval stage. The flour beetle larvae are somewhat larger than an adult flour beetle, it can be 6 mm long. It is not only the size that differs. A larva of a flour beetle has a yellowish brown or beige color. Both front and hind are slightly darker. A flour beetle larva can also be taken as a worm with its chubby shape. Biology and behavior The confused flour beetle belongs…

…e a consistent dark brown color on the body. However, the underside of the larvae is slightly lighter. The larvae are clearly articulated and have long bristles protruding from all its joints. The rear visible joint is equipped with two dark chitin hooks. The larva grows up to 13 mm long. Biology and behavior The Dermestes Lardarius belongs to a group of insects that specialize in cleaning up nature, feeding on the remains of animals and tissue. I…
