Clover Mites: Identification, Prevention, and Control

Identifying Clover Mites

Clover mites are tiny, arachnid pests that resemble red spider mites. However, they have distinct characteristics that differentiate them from their counterparts.

  • Size and Appearance: Clover mites are approximately 1/30 of an inch long, with a reddish-brown coloration. Adult clover mites are typically darker than younger mites and eggs, which are bright red.
  • Feeding Habits: Clover mites feed on over 200 plant species, primarily clover, which gives them their name. They suck the sap from plants, causing silvery discoloration.
  • Identification Test: To confirm the presence of clover mites, crush a few individuals. If they leave a bright red stain, they are likely clover mites.

Preventing Clover Mite Infestations

The best defense against clover mites is prevention. Implementing the following measures can minimize the risk of an infestation:

  • Maintain a Healthy Lawn: Avoid excessive nitrogen fertilization, as it attracts clover mites. Mow your grass at a height of three to four inches to promote root growth.
  • Plant Strategically: Keep trees and shrubs away from your home’s foundation. Plant shrubs at least half their mature size from the foundation, and prune branches to prevent contact with the house.
  • Create a Barrier: Establish a plant-free, grass-free strip around your home’s foundation, covering it with mulch or gravel. Remove leaf litter and vegetation from around your house, as they provide pathways for clover mites.
  • Choose Resistant Plants: Select plants that clover mites dislike, such as marigolds, petunias, zinnias, salvia, roses, barberry, juniper, spruce, arborvitae, and yew.

Controlling Clover Mite Infestations

If clover mites have already invaded your home, several effective control methods are available:

  • Insecticides: Apply insecticides labeled specifically for mite control outdoors. Follow the instructions on the label carefully, spraying in areas where clover mites are present. To prevent indoor infestations, spray around the perimeter of your home, including doors, windows, the foundation, and two feet up on all exterior walls.
  • Sealing Entry Points: Inspect your home for any cracks or holes along windows, doors, or foundations, and seal them to prevent clover mite entry.

Clover Mites vs. Red Spider Mites

Red spider mites also appear as tiny red bugs, but they are distinct from clover mites.

  • Hosts: Red spider mites infest a wide range of plants, including fruit trees, ornamentals, and edibles. Clover mites primarily feed on clover and other plants in your yard.
  • Damage: Red spider mites cause more severe and permanent damage to plants than clover mites. They pierce leaves and suck out fluids, leading to discoloration, distorted leaves, leaf drop, and dieback.
  • Lifecycle: Red spider mites have overlapping generations and a rapid reproduction rate, especially in hot, dry weather.

Frequently Asked Questions

Do clover mites bite or carry diseases?

No, clover mites do not bite or carry diseases, so they do not pose a health risk to humans.

How long do clover mites live?

Clover mites have a lifespan of about one month, with five to six generations per year. They lay eggs in protected locations during the fall, which hatch the following spring.

Will clover mites go away on their own?

Clover mites are seasonal and may disappear on their own. However, a small infestation can quickly escalate into a larger one, so it is recommended to take preventative measures to keep them under control.

How to Keep Crickets Out of Your Home: A Comprehensive Guide

Types of Crickets

In North America, two common types of crickets may invade your home:

  • House cricket (Acheta domesticus): About an inch long, with a yellowish-brown body and dark bands on its head. They feed on various materials, including fabrics, paper, and food.
  • Field cricket (Gryllus): Smaller and darker than house crickets, often found in tall grass or shrubbery. They leap when startled.

Why Crickets Come Inside

Crickets prefer to live outdoors but may enter homes for shelter during inclement weather or through accidental entry. They are attracted to warmth and moisture and often seek these conditions in kitchens, near heat sources, or in cracks and behind baseboards.

Signs of a Cricket Infestation

  • Chirping: Crickets communicate by rubbing their wings together, creating a characteristic chirping sound.
  • Damage: High populations of crickets can chew on fabrics, paper, and other materials.
  • Sightings: You may spot crickets hopping around your home or hiding in dark corners.

Eliminating Crickets

  • Glue boards: Place glue boards in areas where you hear chirping. Add cornmeal as bait to attract crickets.
  • Vacuuming: Use a vacuum hose with an attachment to trap crickets. Empty the canister outdoors.
  • Sprays and baits: For heavy infestations, consider using sprays or baits labeled for cricket control. Follow all label directions carefully.

Preventing Future Infestations

To keep crickets out of your home for good, take the following steps:

  • Seal entry points: Caulk or seal cracks in the foundation, around doors and windows, and any other potential entry points.
  • Remove attractants: Keep the perimeter of your home free of tall grass, weeds, and mulch. Avoid storing firewood or organic materials near the house.
  • Control lighting: Use yellow sodium-vapor lighting outdoors to avoid attracting crickets to your home. Place lights on poles with the lighting directed away from open doors.
  • Maintain cleanliness: Vacuum and sweep regularly to remove cricket feces and other debris that may attract them.
  • Inspect regularly: Check for crickets periodically, especially during warm and moist weather. Take immediate action if you notice any signs of infestation.

Additional Tips

  • Diatomaceous earth: Sprinkle diatomaceous earth around entry points and areas where crickets are likely to hide. It dehydrates and kills insects on contact.
  • Essential oils: Some essential oils, such as peppermint and tea tree oil, have repellent properties against crickets. Dilute a few drops in water and spray around areas where crickets enter.
  • Professional pest control: If you are unable to control the cricket infestation on your own, contact a professional pest control company for assistance.

Fall Armyworms: An Unprecedented Invasion

Introduction

Fall armyworms, an invasive species of caterpillar, are wreaking havoc on lawns and crops across the United States at an unprecedented scale. These voracious pests can turn lush green grass brown in a matter of hours, leaving behind a trail of devastation.

Biology and Behavior

Fall armyworms are the larvae of moths that can travel hundreds of miles in a single day. They lay their eggs on leaves, grass, and other vegetation, and the eggs hatch into caterpillars within a week. The caterpillars have a distinctive Y-shaped head and three stripes running down their bodies.

Impact on Lawns and Crops

Once hatched, fall armyworms feed on the roots and leaves of plants, causing rapid damage and nutrient depletion. Lawns can be turned brown in less than 48 hours, while crops can suffer severe yield losses.

Factors Contributing to the Infestation

This year’s fall armyworm infestation is particularly severe due to several factors, including:

  • Favorable weather patterns that have allowed moths to disperse widely and lay eggs in new areas
  • Large populations of fall armyworms in previous years
  • Reduced natural predators due to pesticide use
  • Susceptibility of certain grass species to fall armyworm damage

Management and Control

Insecticides are the most effective method for controlling fall armyworms. However, they must be applied quickly to prevent significant damage. Reseed only after the threat of a second wave of hatchlings has passed.

Managing Expectations

Even with proper management, it is important to note that fall armyworms can be difficult to control completely. Focus on managing populations and minimizing damage rather than eliminating them entirely.

Long-Term Strategies

To reduce the impact of fall armyworms in the long term, consider the following strategies:

  • Plant resistant grass species
  • Encourage natural predators, such as birds and parasitic wasps
  • Use cultural practices, such as crop rotation and proper irrigation, to make the environment less favorable for fall armyworms

Additional Information

  • Fall armyworms are native to the Americas but have spread to other parts of the world, including Africa and Asia.
  • The caterpillars can feed on over 80 different plant species, including corn, soybeans, and cotton.
  • In severe infestations, fall armyworms can cause millions of dollars in damage to crops.

Call to Action

If you suspect that your lawn or crops are being affected by fall armyworms, contact your local agricultural extension office for assistance. Early detection and management are crucial to minimize damage and protect your valuable plants.
