Winter Pests and Their Adaptations in Riverside and Moreno Valley

The winter season in Riverside and Moreno Valley is typically warm and arid, with average temperatures between 43°F and 68°F. However, some winter events can cause snow and ice to fall in the area. As humans dress warmly and stay inside, the insects in the region have evolved amazing biological adaptations to cope with the cold. So, some pests that do not go dormant in winter are termites, carpenter ants, bed bugs, fleas, and mosquitoes. In the next sections, you will learn how these creatures adapt to the cold season.

Freeze Tolerant and Freeze Avoidant in Winter Pests

Some pests can withstand internal ice formation, while others have the ability to prevent it and supercool their bodies. Below are some pests that exhibit each adaptation:

  • Freeze-Tolerant Pests: Woolly bear caterpillars, gall flies, and some beetles can make proteins, boost water channels, and gather substances to survive freezing.
  • Freeze Avoidant Pests: Cockroaches, spiders, rodents, ants, ladybugs, boxelder bugs, and cluster flies can produce antifreeze, reduce water, and supercool to avoid freezing.
  • Nature’s Antifreeze pests: These pests can make their body fluids antifreeze, lose water, and supercool to prevent freezing in winter. Cockroaches, spiders, rodents, ants, ladybugs, boxelder bugs, and cluster flies are some of them.

Dehydration in Winter Pests

Some pests can avoid freezing by reducing their body water content. This lowers the temperature at which their body fluids freeze, and also decreases the ice formation and damage in their body. Cockroaches, spiders, rodents, ants, ladybugs, boxelder bugs, and cluster flies are some pests that use dehydration as a winter defense.

Migration of Winter Pests

Some pests escape the cold by migrating to warmer areas or entering human structures. For instance, mosquitoes can fly to warmer regions or overwinter in places like basements, sewers, or drains. They migrate to human dwellings to find warmth and shelter, sneaking into cracks, gaps, and even our living spaces. It highlights the need for winter-proofing homes to keep these unwanted invaders out.

Insulation or Insulated Areas of Winter Pests: 

Termites can construct mud tubes that keep their colonies at a constant temperature and humidity level which is a kind of insulation technique. Many pests also look for insulated areas in their environment, such as piles of leaves, stacked wood, or under the snow. These areas provide them with warmth and shelter until the weather becomes warmer.

Continuous Reproduction in Winter Pests

Some pests can continue to reproduce and increase their numbers in winter if they have access to food and shelter. For instance, bed bugs and fleas can lay thousands of eggs in their lifetime, and survive the cold by hiding in mattresses, furniture, clothing, carpets, bedding, or on pets or wildlife. Unfortunately, these pests can cause damage and spread diseases and allergens.

Dormancy, Hibernation, and Overwintering in Pests

There are some words to explain how some pests deal with the cold and lack of food in winter: Dormancy, hibernating, and overwintering. Here is how they differ:

  • Dormancy is a broad term for a resting or inactive state in which metabolism is low and development is stopped. It can vary depending on how severe and long the condition is. 
  • Hibernating is a specific kind of dormancy in which the body temperature and metabolic rate fall a lot, and the activity and responsiveness are very low. It often involves entering diapause, a dormant state caused by environmental cues.
  • Overwintering is the way pests get through or wait out the winter. It can involve hibernation, migration, or other ways to survive the cold. 

Some examples of pests which are not active during winter are: 

  • Male mosquitoes, which die in winter
  • Some female mosquitoes which hibernate in hollow logs or other hidden places
  • Ladybugs that hibernate in big groups, often inside houses, under siding, or in wall spaces.
  • Boxelder bugs, that hibernate in dark places, such as attics, basements, or cracks in walls.
  • Cluster flies, which hibernate in attics, wall spaces, or other isolated areas.

How to Avoid Winter Pests Infestations?

To prevent pests from invading your home during the cold season, you need to take care of both the inside and outside of your house:

  • Start by sealing any cracks, holes, or gaps in your home exterior, especially where pipes or wires enter the house. This will prevent pests from finding entry points. 
  • Next, check your yard for anything that might attract pests, such as standing water, leaf piles, or wood piles. Remove them or keep them away from your house. Also, cut back any overgrown plants or bushes, and avoid having water, mulch, or other lures near your house. This will reduce the food and shelter sources for pests. 
  • Then go inside your house and thoroughly clean and disinfect it. This includes every room. Make sure you vacuum the carpets, mop the floors with hot water, wipe the counters, wash the bedding and clothes with hot water, and store the food in sealed containers. This will eliminate any crumbs, spills, or odors that might attract pests. 
  • Also, keep your basement, crawlspace, and attic well-ventilated and dry, and fix any leaks or drips. This will prevent moisture and mold problems that might attract pests. 
  • Finally, check your vents and chimneys, and inspect your roof and siding for any damage. This will prevent pests from nesting or hiding in your house.

Pest Control Methods for Controlling Winter Pests

There are four types of pest control methods in winter: biological, chemical, physical, and cultural. Each type has its pros and cons, depending on what kind of pest, how many pests, how much money, and how much effect on the environment. Check the summary of each type below:

Biological Pest Control

Biological pest control uses pests’ exterminators, like hunters, parasites, or germs, to reduce or stop their reproduction. For example, ladybugs fight aphids, and nematodes kill grubs. The pros of biological pest control are that it is safe, effective, and sustainable, as it spares other organisms and prevents resistance. The cons are that it is slow, unsure, and hard to monitor, as it depends on weather, availability, and compatibility.

Chemical Pest Control

Chemical pest control uses substances, like pesticides, to kill or repel pests. For example, pyrethroids kill mosquitoes, and neem oil deters mites. The pros of chemical pest control are that it is fast, reliable, and easy, as it can target many or a few pests. The cons are that it can be harmful, expensive, and unsustainable, as it can affect humans, animals, soil, water, and air, or cause pest problems.

Physical Pest Control

Physical pest control uses barriers, traps, or devices to keep out, remove, or kill pests. For example, screens stop flies, or sticky traps catch rodents. The pros of physical pest control are that it is safe, cheap, and simple, as it does not use chemicals or biological agents. The cons are that it is hard work, time-consuming, and ineffective, as it only handles existing or a few pests, and may not stop future infestations.

Cultural Pest Control

Cultural pest control uses practices or behaviors to make the environment or the host less appealing for pests. For example, sanitation removes food and water for pests, or crop rotation disrupts pest life cycles. The pros of cultural pest control are that it is preventive, holistic, and long-term, as it reduces other pest control needs or improves them. The cons are that it is complex, hard, and costly, as it may require habit, attitude, or policy changes, or have trade-offs or conflicts with other goals or interests.

To sum up, different pest control methods in winter have their pros and cons, and the best method varies depending on the case and the objectives of the pest manager. A mix of methods, also called integrated pest management (IPM), can be the most powerful and eco-friendly way to deal with pests in winter.
