Spring in Iowa brings a welcome change in weather, but it also signals the return of some unwelcome pests. As temperatures rise and flowers bloom, many pests become more active, seeking food, shelter, and mates.

While some springtime pests are merely a nuisance, others can cause significant damage to your home or pose health risks. By understanding the most common pests in Iowa during this season, you can take proactive steps to protect your home and family. Janssen Pest Solutions is here to teach you about 10 of the most common spring pests in Iowa!


Key Takeaways

  • Common Springtime Activity: As temperatures rise in Iowa, many pests become more active, making spring an important time to be vigilant against potential infestations. Pest control and prevention in Des Moines becomes very crucial.
  • Ants on the Move: Ants, including odorous house ants, carpenter ants, sugar ants, and pavement ants, become particularly active in spring. These pests often search for food and moisture, making them more likely to invade homes.
  • Mosquitoes and Ticks: Warmer weather and standing water create ideal conditions for mosquitoes, which can transmit serious diseases. Ticks, on the other hand, become more active and pose a risk of Lyme disease and other illnesses.
  • Nuisance and Damage: Some pests, like boxelder bugs and ladybugs, are simply a nuisance, while others, like termites and carpenter ants, can cause significant structural damage.
  • Prevention is Key: Sealing cracks, eliminating food sources, and maintaining cleanliness are crucial steps to preventing pest infestations. Professional Des Moines pest control services should be used for significant or persistent problems.

1. Ants

  • Why They’re Common: As temperatures rise, ants begin foraging for food after the long winter hibernation. Spring warmth awakens their colonies, and they move out in search of food and water.
  • Types in Iowa: Odorous house ants, carpenter ants, and pavement ants are the most common species in Iowa.
  • Impact: While some ants, like odorous house ants, are harmless, others, such as carpenter ants, can cause structural damage by nesting in wood.
  • Prevention Tips: Seal cracks around doors and windows, store food in airtight containers, and regularly clean up crumbs and spills.

2. Mosquitoes

  • Why They’re Common: Standing water is a breeding ground for mosquitoes. The warm temperatures of spring create ideal conditions for these pests to multiply.
  • Impact: Mosquitoes can transmit serious diseases, such as West Nile virus and Zika virus. They’re particularly bothersome during warm evenings.
  • Prevention Tips: Eliminate any standing water around your property, wear mosquito repellent, and consider installing screens on windows.

3. Fleas

  • Why They’re Common: As pets spend more time outdoors, fleas become more active in the spring. They are most commonly spread by pets, but they can also infest your home.
  • Impact: Fleas can cause itching and irritation in pets and humans. If left unchecked, fleas can lead to allergies and even bacterial infections.
  • Prevention Tips: Treat pets with flea preventatives, vacuum regularly, and wash pet bedding to remove any flea eggs or larvae.

4. Ticks

  • Why They’re Common: Spring is the peak season for tick activity. As the weather warms, ticks become more active in search of hosts to latch onto for feeding.
  • Types in Iowa: Deer ticks and wood ticks are the most common.
  • Impact: Ticks are vectors for Lyme disease, Rocky Mountain spotted fever, and other illnesses. They can latch onto both pets and humans.
  • Prevention Tips: Use tick repellent, wear long sleeves and pants when outdoors, and check for ticks after being in grassy or wooded areas.

5. Boxelder Bugs

  • Why They’re Common: As the weather warms, boxelder bugs leave their winter hibernation sites in search of warmth and food. They tend to invade homes during spring and fall.
  • Impact: While they don’t cause damage or pose health risks, boxelder bugs are a major nuisance when they invade your home in large numbers.
  • Prevention Tips: Seal cracks around windows and doors, and remove any boxelder bugs you find indoors by vacuuming or using a mild insecticide.

6. Ladybugs

  • Why They’re Common: Ladybugs emerge from their winter hibernation in the spring, often entering homes in search of warmth.
  • Impact: While ladybugs are beneficial in the garden (they eat aphids), their presence indoors can be bothersome. They can leave stains if crushed.
  • Prevention Tips: Seal cracks and openings around windows and doors to prevent ladybugs from entering.

7. Spiders

  • Why They’re Common: Spiders become more active in spring, seeking food and mates. They often move indoors, where they find shelter and abundant food sources (such as insects).
  • Common Species: Common house spiders, cellar spiders, and garden spiders are commonly seen in homes.
  • Impact: While most spiders are harmless, their webs and presence can be unsettling, and some species may bite if provoked.
  • Prevention Tips: Regularly clean and remove spider webs, seal entry points, and reduce clutter where spiders may nest.

8. Wasps and Hornets

  • Why They’re Common: As temperatures warm, wasps and hornets start building nests and foraging for food. Early spring sees the emergence of queen wasps that begin establishing colonies.
  • Impact: Wasps and hornets are aggressive when threatened and can sting multiple times, causing painful reactions. In rare cases, stings can lead to allergic reactions.
  • Prevention Tips: Be cautious around nests and avoid disturbing them. If you spot a nest near your home, contact a professional pest control service for removal.

9. Termites

  • Why They’re Common: Termite swarming season begins in spring when mature colonies send out winged termites to establish new colonies. These termites are particularly active after rain.
  • Impact: Termites feed on wood, causing significant structural damage if left unchecked. They are one of the most destructive pests to homes.
  • Prevention Tips: Regularly inspect your home for signs of termite activity, such as mud tubes or hollow-sounding wood. Consider professional inspections and treatments if necessary.

10. Mice and Rodents

  • Why They’re Common: As temperatures warm, mice and other rodents leave their winter nests and begin searching for food. They may enter homes through small gaps or holes.
  • Impact: Rodents can chew through wires, insulation, and wood, causing damage. They also pose health risks by spreading diseases like hantavirus and salmonella.
  • Prevention Tips: Seal entry points around doors, windows, and foundations, and eliminate food sources by storing food in sealed containers.
