If you’ve noticed bee mites around your hives, you might be wondering how to get rid of them. One way is to use a salt solution. Alternatively, you can use formic acid or other alkali metal salts. Using essential oils or screening the bottom board of your hives can also help.

Formic acid kills bee mites

The use of formic acid kills bee mites and prevents them from breeding in beehives. Beekeepers use the chemical to reduce mite numbers and a variety of treatment options exist. Most treatments work by delivering active ingredients over a prolonged period. One study found that a 17-hour application of 50% formic acid killed mites in adult bees and worker brood. The results were similar for acetic acid but not as effective.

Formic acid is a colorless liquid with a penetrating odor. It is miscible with water and is partly soluble in other solvents. At high concentrations, it is corrosive. The acid is found naturally in the atmosphere and is used for many different purposes by humans. It is used by beekeepers to kill Varroa mites and tracheal mites. Due to its low toxicity, it can also be used as a food additive.

There are two common methods for using formic acid to kill mites in honey bee colonies. One method involves using a single formic acid pad and the other involves using more than one. The second method is ideal for smaller colonies or if the temperature treatment window is close to the limit. However, this method may not be effective for mites that are in brood cells.

While beekeepers use Formic Pro to treat their colonies, they should be aware that this method is not without risks. Using the chemical may result in the death of some bees and the destruction of their brood. This is especially dangerous in colder climates.

Alkali metal salts

In an experiment with caged honeybees, alkali metal salts, such as LiCl, were fed to the bees for several days. However, shorter periods would be preferred for practical beekeeping. In this study, 25 mM LiCl was the most effective concentration. The treatment was followed by a sugar solution for six days. The results showed that 25 mM LiCl killed 92.9% of mites and was effective in treating Varroa mites.

Oxalic acid is an organic compound that is present in many foods and is a natural mite control agent. It is a crystalline solid that dissolves in water. It is commonly used in cleaning solutions and bleaches. In beekeeping, oxalic acid should be used with caution because it can harm bees if used too much.

Alkali metal salts have been proven to be effective in treating bee mites. It works by disrupting the engorgement of parasitic fungi. The alkali metal salts can also kill bee mites in a safe manner. Alkali metal salts are available commercially, and the use of these products is becoming more common in beekeeping. The effectiveness of these products is being tested in trials across the country.

These compositions inhibit the growth of mites in honeybee hives by disrupting their biological functions, including respiration and neural activity. Once they reach a critical concentration, the mites die.

Essential oils

Essential oils are known to have an acaricidal effect on mites. Some oils, such as wintergreen oil and tea tree oil, can kill mites or disrupt their life cycle. However, the exact effect of these oils on mite populations is unknown. In order to find out whether essential oils are effective against mites, scientists tested 30 essential oils. They performed a glass-vial residual bioassay to determine their varroacidal efficacy. The oils that showed the highest varroacidal efficacy were then tested in a complete exposure assay. The tests were conducted on five bees and five mites in a Petri dish. Each treatment was repeated five times to confirm a certain essential oil’s efficacy.

Essential oils are known to disrupt mites’ molting and cuticle processes, which inhibit their growth and fecundity. Eucalyptus and lemon oils contain fumigants that can kill mites. Eucalyptus oil contains 1, 8-cineole, which is the main component responsible for its pesticidal action. Neem oil contains salannin, which provides both repellant and anti-hormonal properties.

Essential oils applied as grease patties on bees’ hives are effective in keeping mite populations low in winter. However, this treatment is not effective if the hive is already heavily infested. Therefore, it is not recommended for use in severely infested hives.

Screened bottom boards

A screen-topped bottom board will provide ventilation for your colony without allowing too much heat to escape. A screen-top board will not allow bees to walk on it, but it will provide the necessary ventilation. Ideally, the screen will allow you to see the hive easily, allowing you to treat the mites without having to open the hive’s entrance.

When selecting treatment methods, it’s important to determine the mite load before applying any products. A sugar roll test can help you determine the most effective treatments for your particular mite problem. For example, a screened bottom board will allow you to reduce the mite load of your bees by trapping them in the screened board. If used correctly, a screened board will eliminate 10-20% of the mites in the colony. A screened board will also help chill the brood during cool weather.

A solid board will also help prevent fire ants from invading the hive. Since ants are attracted to loose debris, screened bottom boards will prevent them from getting into the hive. A screen bottom board will also help control excess moisture. Screened boards are inexpensive and easy to build.

A screened bottom board will help keep out Varroa mites, which are an essential part of the management process for bee colonies. A screened bottom board is one of the most effective ways of treating bee mites. These boards are commonly used in foreign countries to control the pests.


Thymol is a monoterpene derived from garden thyme and used to treat mite infestations. It is relatively safe for human use, though it should be handled with nitrile gloves and under proper ventilation. The standard dosage of thymol is eight to 12 grams, which will kill one to three mites. It should be noted that thymol crystals evaporate rapidly, so use caution when handling.

If you are using Thymol to treat bee mite infestations, you need to follow the instructions for using the product. You must also make sure to follow the instructions carefully so that you do not cause damage to bees or create resistant mite populations. You should also remove the treated frames as soon as possible, preferably after 42 days or 56 days. This will help prevent the development of resistant Varroa populations, which are common in beekeeping.

Thymol is effective when mixed with other ingredients. For example, ApilifeVar contains thymol mixed with menthol, camphor, and eucalyptol. It acts most effectively when temperatures are between 15 and 30 degrees. If you want to use Thymol as a topical treatment, you can use a gel or a strip containing it. Just make sure to stir the gel first.

It should be noted that there are many risks of using Thymol to treat bee mite infestations. The main dangers are associated with incorrect application and DIY techniques. You should use registered products that are safe to use on your honey hives. You should follow the instructions on the label for proper use.


The Apiguard for treating bee mite problems with salt is a natural treatment that is effective and safe for bees and their workers. This treatment can be used on adult and brood bees. It works best when applied at intervals of seven days. It should be applied with a non-absorbent pad. In hot weather, the product may dry out and become ineffective.

After the treatment, the percentage of adult bees showing Varroa was not significantly different from the predicted percentage of adults. The control colonies showed a slight seasonal decline in Varroa numbers. The results of this study showed that Apiguard and Apistan (r) were effective in reducing mites in the bees.

The Apiguard product was tested on varroa mites as well as acarine, chalkbrood, and tracheal mites. In most cases, it killed Varroa mites within six hours of exposure, but residual activity quickly disappeared afterward. In contrast, Apiguard and HopGuard showed a higher percentage of persistent acaricidal activity than the other treatments.

The use of Apiguard for treating bee mite problems with salt is a safe and effective method of controlling mites in bee colonies. However, it is not recommended to use this product on honey bee colonies during the making of honey and while the supers are still in place. In addition, the pesticides do not kill the mites in the capped cells. The store-bought pesticides have cornstarch, which irritates the bees’ stomachs. Homemade pesticides are safe and are made from natural ingredients.
