As around 400,000 species of beetles have been identified, it is clear that they come in many shapes and sizes. Some can be beneficial and others can cause some problems for crops and even homes. Depending on their species, beetles feed on plants, animal fibres, decaying materials, and so on. Some kill harmful insects while others are destructive pests themselves.
As for the last ones, in case of an infestation of your crops, or of your home, you will need to know how to manage them and which method to apply, to keep them away. Some beetle larvae, for example, the carpet beetle, can attack natural fibres and feathers, damage the wool and other materials you have in your home. Others feed on hardwood or bamboo or any other type of wooden furniture. In the kitchen, flour and wheat beetle can affect your food. They can also cause great damage if they manage to infest production plants or shops. Your yard can also be attacked by beetle larvae. They can damage lawns and landscapes by attacking roots and grass, and leaves can also be attacked by elm beetles.
Beneficial ones, such as the ladybug, will feed on plant pests such as aphids and mealybugs, their presence is highly valued in the garden. However, even if they can be annoying in summer and autumn, hundreds of these creatures can be found crowded in the vicinity of the houses as they seek shelter given the arrival of winter.
Types of beetles and methods of eradication
The carpet beetles
When dealing with an infestation of any type, the first step is to identify the type of parasite to set the correct eradication method.
As for carpet beetle infestation, you must be very careful with the control measures you will apply, as they must be carried out completely due to the persistence of this parasite. They can cause significant damage to carpets, clothing and any other type of fabric they come into contact with. You can identify carpet beetle infestation by the traces they leave behind, such as pellets of feces and flaky skin. You can expect to find both larvae and adults around and they can be easily recognized by the brown stripes around the body of the larvae along with skin-like terminations on one or both ends, and the oval shape of the adult’s body. . They can come in a range of colours,
Once you have identified the type of beetle, you will need to find the source of the infestation which is indicated by a high concentration of peeling skin and pellets of feces. They normally appear in bathroom rugs or dark places like air ducts, basements and attics, but they can also be attracted to food pantries, dog food, fresh flowers, and paintbrushes.
Once you have found the source of the infestation, you will need to thoroughly clean the entire area. Vacuum all rugs in the house to make sure the beetles have not spread to other rooms. Try to vacuum all upholstery that cannot be washed in the washing machine and try to maintain an adequate level of hygiene throughout the house, to avoid the development of future generations of carpet beetles. Depending on how severe the infestation is, it may be necessary to vacuum several times a day, but remember to throw away the infested clothing and the vacuum cleaner bag to prevent the beetles from escaping and causing other damage.
If your clothes have not been heavily infested, then you do not have to throw them away, the best solution to keep them out of the infestation is to wash them in boiling soapy water to remove all traces of the infestation and then store them in closed containers. hermetic. You can also steam clean carpets and upholstered furniture to make sure eggs and larvae are also eliminated.
If just vacuuming and washing carpets doesn’t give you enough safety, you can use insecticides in the form of aerosols or dust. There are specific solutions on the market against carpet beetles that you can apply in the cracks and crevices where they might hide. In general, carpet remedies with insecticides including chlorpyriphos, bendiocarb and allethrin are the most useful against carpet beetles. You can also try sprinkling the affected area with boric acid, as this solution is non-toxic to humans and will kill almost any insects that come into contact with it. However, pay attention to the whitening effect, so don’t use it on coloured materials.
Traps with pheromones can also be used against carpet beetles. They come in the form of glue traps that can be placed near cracks and crevices or any other area where you see beetles coming out. The traps will attract the beetles and kill them and based on the number of trapped beetles you can get an idea of how big the infestation is.
To prevent them from entering the house, you can also use outdoor treatments, using liquid insecticides along with the soil areas near the house and around the lower portions of the foundation. You can apply them using a low-pressure sprayer. This is an important step, especially if you suspect that the infestation originates in a place that is connected to the outside of the home, such as ventilation or air ducts. You can also consider other potential routes of entry such as windows, door frames and pipes. An extra measure is to remove bird nests around your home as carpet beetles are used to lay their eggs there.
Once you’ve successfully rid yourself of carpet beetles, be sure to apply preventative measures, such as protecting endangered items, inspecting flowers before bringing them indoors, and keeping doors and windows closed. Carpet beetles don’t like plastic bags so storing your off-season clothing in plastic bags will protect them from these pests. Also opening your closets several times a day and exposing your clothing to fresh air and sun can keep beetles away. Place slices of cedar or mothballs in storage areas to keep the beetles away and clean your carpets regularly to avoid re-infestation.
The wheat and flour beetles
When it comes to an infestation due to wheat and flour beetles, the steps you need to take to eliminate them are different. Flour beetles are common in homes and food shops and attack flour and grain stores. They deposit their eggs directly in flour, grains, or dry pet foods, where they can remain for several months before hatching. After brooding, the larvae begin to eat the flour around them, altering its quality and causing an unpleasant odour. Adults can also crawl into packaging and easily propagate from one product to another.
When you discover an infected product, not only will you need to get rid of beetles, but you will also need to find the source that caused the problem. The product was likely contaminated before taking it home. After finding the source and getting rid of the contaminated product, you will need to disinfect the whole area and apply preventive measures to prevent it from happening again.
Check carefully all food products that are not stored in airtight containers. Bear in mind that these parasites can easily move from one product to another, especially if stored in paper bags or cardboard boxes. The best way to store and protect food is with plastic bags that close properly or glass jars. Other foods such as pasta, biscuits, rice, canned food and bread can be contaminated with the infected flour. Since you are unable to see the beetle eggs with your naked eye, if you suspect a container infestation it is best to simply throw it away.
After removing all affected products, cleaning the area is the next step. Vacuum up any food residue left on the shelving and crevices and clean cupboards and pantries with a mix of soapy water or even a little bleach, as this will kill the remaining eggs. After they have been cleaned and dried, you can cover the shelves with sheets of paper, just to add some extra protection against any future invaders. It is also possible to use eucalyptus oil or tea tree oil to discourage the appearance of future beetles, as these oils have a powerful smell that the beetles do not like. Be sure not to offer these pests a thriving environment, as they prefer a humid and warm area to develop.
Applying insecticides is the last decision you need to make. If you feel that you have not removed all possible sources of infestation by removing the affected packages and cleaning the whole house, you can apply the insecticide, which should get into cracks and crevices, to eliminate any flour beetles that are hiding there. Considering that you will need to apply it next to food, the best type of insecticide is diatomaceous earth. Being a food-based insecticide, it will be harmless to humans but will be effective in targeting and killing beetles, through their exoskeleton and causing them to die from dehydration. Prevention is the key to stopping future infestations, so be careful when buying new corn or wheat products. Always buy small quantities to be able to use them quickly, as larger quantities that are not used for a long period will be more likely to develop beetles. This also applies to cereal boxes, dry dog foods and spices. Just to be on the safe side, after purchasing the products, you can freeze them for 10-25 days to kill any traces of eggs or larvae and then store them in an airtight container. Always clean up crumbs and spills and always keep the entire surface of the house and yard clean. dry dog food and spices.

As noted above, the ladybug is not considered a destructive pest. It is very advantageous, as its preys are herbivorous homopterans such as aphids or phytophagous insects, which are agricultural parasites. Multiple ladybirds lay eggs instantly in aphid and phytophagous insect settlements to provide their larvae have a direct food source. However, even these popular insects can sometimes become harmful. Typically, when temperatures drop to 60 ° F (18 ° C) in the late afternoon, after a colder period, they will move to or into sunlit buildings.
Swarms of ladybugs fly to buildings between September and November depending on the weather and atmospheric conditions. Houses or other buildings near fields or woods are particularly suitable for infestation. First, they will go into hibernation gradually by exposing themselves to the sun on the walls before entering their seats at night or in cold periods. The same is true in reverse when they emerge from hibernation in the spring. Entering the buildings through the cracks, coming inside the rooms, as they are guided by the heat coming from the rooms, so you can also find dead ladybugs around the windows, as they try to find their way out.
To eliminate these parasites, it is necessary to use a residual insecticide, placed inside and outside the windows, on walls, ceilings or mezzanines. You can also use the insecticidal mist to make sure it reaches all the cracks and crevices in the walls. These eradication methods will eliminate most of the problem, but not the entire infestation, because large numbers of insects will be hibernating in areas that do not come into contact with the applied insecticide, such as niches, boxed areas in roofs or between felt tiles or shingles. Aerosol insecticides can last 1-2 months after application, but the more time passes, the less effective they will be. Insects will only be affected if they come into contact with the treated areas. Another type of solution that can be used is boric acid, but as with other insecticides, ladybugs will have to come into contact with it. For a smaller infestation, solutions with strong vapours, such as camphor or menthol, can be used. Apply some citrus or lemongrass perfume in places where ladybugs were first seen; not only does this erase any scent they have left behind, limiting the chances of any new ladybug feeling it and being drawn to it, but it is also believed to repel ladybugs, as they don’t like the strong scent.

Traps made of soap and water have also been shown to be effective. Just fill the bowls with the mixture and place them in strategic places, such as on windows or near lamps; the reflected light will attract the ladybugs, and the soap will cut the tension of the water so that when they fall inside, they will not be able to rise again and take flight and thus drown. During the summer, many can be prevented if these problems are caused by the ladybug, checking the outside of your home and plugging the cracks around the windows and doors. Check the attic, roof and vents, repair broken window panes and check the seals on all exterior doors. Be sure to plug any holes leading into the attic from inside your home. These measures of prevention z I on and should keep the ladybugs out and keep your home free from any infestation.
