These insects are additionally known as flower beetles or flower flies. Despite their menacing appearance, hoverflies are essential pollinators that provide advantages to crops, plants, and blossoms.Syrphidae, the scientific nomenclature for hover flies, are aphid-shaped insects that vary in size from 1/16 to 1/2 inch. They possess short antennae, large eyes that occupy a significant portion of their cranium space, and extended wings when at rest. However, they can become bothersome parasites if they manage to enter residences. Because of their tenacity and bee-like appearance, hover flies frequently elicit inquiries from householders regarding effective methods of extermination. This comprehensive guide will examine the behavior of hoverflies, the reasons they enter residences, and the most efficacious chemical and natural remedies for eliminating an infestation.
What are Hover Flies?
Hover flies are classified as Syrphidae, which are aphid-shaped insects that differ in length from 1/16 to 1/2 inch. These organisms have short antennae, prominent eyes that occupy a considerable amount of cranial space, and at rest, extended wings.Typically black and yellow or black and white in color, they resemble wasps or bees. This mimicry affords protection against predators that avoid venomous insects.
Owing to their coloration with venomous insects, hover flies are non-venomous and do not bite. Their oral structures have evolved to extract pollen and nectar from blossoms. Adult hover flies and their larvae both consume scale insects, aphids, and other plant pests that cause injury to gardens and crops. As a result, they serve as natural nuisance controllers and highly advantageous pollinators in agricultural and outdoor environments.
In North America alone, over 1,000 of the over 6,000 known species of hover insects reside. Preferred species of domestic hoverflies in the United States and Canada include Eristalis tenax, Toxomerus marginatus, and Helophilus pendulus.
Why Do Hover Flies Enter Homes?
Since flowers attract hover flies, they feed outdoors for the majority of the day on pollen and nectar. However, under specific circumstances, they may be compelled to enter the home and become unwelcome guests. These are some potential entry points for hover insects into homes:
In order to find refuge during periods of precipitation or strong winds, hover flies will seek out covered areas.. An open door or window provides easy access inside.
Hover flies may enter a dwelling through the presence of houseplants, potted flowers, or entryways in order to consume the flowers or aphid parasites that are present.
Attracted to Lights at Night –
Attracted to Lights at Night – Hover flies may be enticed indoors by the glow of outdoor lights at twilight, persisting in their flight while attracted to the lights.
Following Warmth in Fall – As autumn temperatures begin to decline, hover flies may perceive dwellings as warmer environments to spend their time prior to the onset of winter.
Capunable of Escaping—Occasional instances arise where hover flies inadvertently enter enclosed spaces and encounter difficulties navigating back outdoors via screened or closed windows.
Understanding the factors that cause hover fly infestations inside residences enables property owners to prevent fly entry or eliminate attractants that draw them inside. Once in, they can flutter around rooms in search of exits, food or dark hiding places to roost.
Natural Techniques of How To Get Rid of Hover Flies
There are natural alternatives to chemical pesticides for repelling and eliminating hover flies from the residence without causing damage to these beneficial pollinators. Here are some effective natural techniques:
Block Entry Points
In areas susceptible to hover fly ingress, such as around windows, vents, attic hatches, or doors, caulk any crevices or gaps. Use caulk or weatherstripping.
Install screens that fit snugly over windows and entrances that are left ajar to allow for ventilation and airflow. Patch any holes or rips in the existing screens.
Remove Attractants & Shelter
Move houseplants located near entryways further inside or outdoors to discourage hover flies from flying in.
Remove any accumulated grime, dust, or debris that could potentially serve as a cover for hover flies to roost. Clean window sills, shelves, attics and basements.
Insect infestations on indoor or outdoor plants that attract hover flies in search of sustenance should be identified and eliminated.
Use Repellent Scents
Apply essential oils such as lemon, eucalyptus, mint, or orange through an oil diffuser around entryways. The fragrances naturally deter hover flies.
For insect repellency, position cotton balls dipped in oil or freshly sliced lemon or orange slices around entrances and windows. Refresh weekly.
Set Traps Outdoors
Use a large bowl or bucket filled partway with vinegary water or beer outside. Smells attract flies, but they will perish if they come into contact with liquid.
Hang sticky fly traps near external entryways to intercept hover flies before indoors. Change traps frequently when full.
Catch and Release
Gently catch individual hover flies indoors using a clear cup and slip of paper.
Reintroduce them outside unharmed as an alternative to striking.
Although perseverance is necessary, natural methods of removal prevent the destruction of beneficial hover flies and the creation of toxic indoor environments. Tailor solutions in accordance with the primary entry points into the residence.
Be diligent and it becomes easier to prevent future incursions.
Chemical Hover Fly Control Methods
When natural remedies for persistent or severe hover fly infestations within residences appear to be ineffective, restricted insecticide use may offer some solace. However, products must be utilized with care to prevent potential health dangers to the family. Some chemical control options include:
Indoor Insect Foggers or Bombs
Utilizing insecticide fumigation as a final resort can effectively eradicate hover flies from indoor environments. However, these chemicals spread throughout a home and linger, posing risks to pets and children. Ventilate thoroughly after using.
Space & Surface Sprays
Direct application of insecticidal aerosols containing pyrethrins, DEET, or other approved active ingredients is recommended for areas inhabited by clusters of hover flies. Safety data documents ought to be thoroughly examined prior to employing any chemical indoors.
Outdoor Barrier Treatments
Insectarily barrier sprays containing synthetic pyrethroids should be applied along exterior foundations, screens, and entrance points where hover flies are infiltrating the structure. Use in moderation to avoid potential runoff issues.
Insect Growth Regulators (IGRs)
IGRs disrupt an insect’s molting process and development. Around the exterior perimeter, apply liquid or granular formulations containing methoprene, pyriproxyfen, or other IGRs to prevent the maturation of hover fly larvae.
While some fast-acting chemical controls exist, natural methods are favored for their lack of toxic effects on people, pets and the environment. Consider implementing a combination of techniques, such as exclusion and targeted applications, for integrated insect management. With patience, an infestation can often be resolved without poisons.
Ongoing Hover Fly Prevention
Implementing preventive measures to avert hover fly infestations is preferable to responding to infestations seasonally. The presence of hoverflies inside a residence can be reduced by installing exclusion barriers and eliminating attractants near entryways.
Gaps and crevices surrounding windows, vents, utility pipes, and hatches in the cellar
Install weatherstripping and door sweeps that fit snugly on exterior doors
Install and maintain screens in good condition on windows
Ensure trees and vegetation are properly pruned away from structures
Inspect siding, roof material and trim for openings and make repairs
Sweep cobwebs, debris and accumulated dirt from under porches, decks and eve areas
Remove any piled wood, trash, unused equipment offering shelter near foundations
Control weeds, landscape plants or gardens attracting pest insects that lure in hover flies
Monitor for aphid infestations on houseplants or garden plants near entry areas
With a few preventive maintenance practices, homes can be made far less inviting to hover flies seeking access inside. An ounce of exclusion is worth far more than yearly reactive treatments. By cutting off their entry routes, these common yet beneficial insects can easily be kept outdoors where they belong.
