A ladybug
There are 150 species of ladybugs in the United States. However, it is the Asian ladybug or Harmonia axyridis that causes allergies in people. These bugs were first seen in the United States in 1916. Scientists continued to release them at various locations throughout the country to control the aphid population, according to the United States Department of Agriculture. However, the propagation of Asian ladybugs has become a problem, and because of their abundance, some people develop allergies to the Asian ladybug.
Significance
Ladybugs primarily become a problem for allergy sufferers in the fall, when they move indoors for hibernation. According to a Louisville School of Medicine survey, up to 50 percent of the people in some areas of the eastern half of the United States believe they are allergic to ladybugs.
Cause and Effect
Asian ladybugs emit a smelly, orange-colored fluid as a defense mechanism. The fluid contains certain proteins to which some people are allergic. Symptoms of ladybug allergies can include rashes, itchy eyes, runny nose and sneezing.
Identification
An allergist can detect a ladybug allergy by conducting skin tests that are similar to the ones they use for pollen, grass, and other common allergens. The test's prick will usually cause a red lump or wheal if a person is allergic to ladybugs.
Types of Treatments
A person may get temporary relief from ladybug allergies by taking antihistamines or using over-the-counter nasal sprays for congestion. A doctor may prescribe corticosteroids for more severe reactions.
Prevention/Solution
A person with ladybug allergies should look for cracks in window sills, weather stripping and doors, especially as fall approaches. Allergy sufferers can also use pesticides around the perimeter of the home to keep ladybugs out.
