Pests for Every Season

Every season has its own distinguishable characteristics. These conditions determine which kind of flora and fauna thrive at different times of the year. Some creatures do so well during a particular season that their population increases are regarded as “pest levels.” Identifying seasonal pests is a handy skill to prevent infestation.


Spring sees the reawakening of plant life after winter hibernation. Flowers, trees, and shrubs aren’t the only living things that regenerate in the warming months. With a moderate and moist environment (and renewed food supplies), spring is an ideal season for pests like:

Pests for Every Season

  • Ticks
  • Flies
  • Cankerworms
  • Mosquitoes
  • Ants


Insects love the heat of summer. They can also move faster during this season and evade predators. They can eat and breed — and multiply. Common summer insects include:

  • Cockroaches
  • Spiders
  • Yellow Jackets
  • Bed bugs
  • Wasps, bees, and hornets

Pests for Every Season


In the autumn months, most animals are preparing reserves and establishing nesting grounds for the winter. Small animals, however, are more vulnerable during this time and would likely choose a permanent fixture (e.g. gardens, homes, and other buildings) as their winter retreat. Pests that can become problems at this time are:

  • Rodents
  • Bats
  • Slugs and Snails
  • Stink Bugs
  • Birds


During the winter, most plants and animals slow down. Potential pests (or insect eggs) hide to survive until spring. With your home providing warmth and food, more potential pests would try to build their nesting ground indoors. The most common winter pests are:

  • Mice and rats
  • Raccoons
  • Firewood bugs
  • Termites
  • Cockroaches

Pests for Every Season

How to prevent possible infestation

1. Remove food sources. Clean food spills and crumbs, seal food containers, and properly dispose of food waste. With no food source, hungry pests are less likely to raid your pantry.

2. Dry out moist areas in your home. Moisture attracts pests like ants and flies.

3. Seal all openings. These include cracks in your walls, attic windows, and chimneys. Repair window screens and replace door seals. Pests (like rats and mice) can sneak into places with very small gaps.

4. Hire pest control and removal service experts. Some pests can’t be managed by simple home remedies, and you might end up worsening your pest problem. Professional pest controllers know how pests behave and know how to eliminate the problem.

Do Rodents Carry Germs

Rodents are survivors, making them top transmitters of human disease. They also reproduce quickly. One pair of rats can produce almost half a billion offspring in three years. They can swim for three days and pass through holes smaller than their bodies a handy ability for evasion and escape. They will eat almost anything (even their own waste) and carry germs responsible for several human illnesses. Managing rodent populations with a professional extermination/removal services helps control disease.

Germs carried by rodents:

Do Rodents Carry Germs

1. Hantavirus. Hantavirus is a life-threatening virus spread by rodents through urine and fecal droppings. While Hantavirus does not make rodents sick, it causes Hantavirus Pulmonary Syndrome (HPS), a severe and sometimes fatal respiratory disease. Without immediate treatment, HPS deaths can occur between 1-2 days after severe breathing problems begin.

2. Lymphocytic choriomeningitis virus (LCMV). LCMV causes a neurological disease called Lymphocytic choriomeningitis (LCM). Humans contract LCM through exposure to fresh urine, fecal droppings, saliva, or nesting materials from infected rodents. Fever, pain, and nausea are the first signs of LCM, followed by confusion, mobility problems, and hallucinations.

3. Streptobacillus moniliformis. This pathogen is known for causing “rat bite fever,” a rare illness with symptoms including chills, fever, joint pain, and rashes. Although it can be treated with antibiotics, more severe complications may include abscesses in the brain or soft tissue; infection of heart valves; and inflammation of salivary glands, tendons, and the heart lining.

4. Leptospira. A virus responsible for Leptospirosis, this can be transmitted to humans and pets through rodent urine and waste. Signs and symptoms of Leptospirosis include high fever, chills, headache, abdominal pain, diarrhea, and rashes. Without antibiotic treatment, Leptospirosis can lead to kidney damage, meningitis, liver failure, respiratory distress, and death.

5. Salmonella. Rodents carry Salmonella as a normal component in their bodies and can spread this bacteria through fecal droppings. Salmonella causes food poisoning, with frequent diarrhea and fever and painful stomach cramps.Do Rodents Carry Germs

Germs indirectly carried by rodents:

1. Borrelia burgdorferi. This is found on ticks that feed on rats. It causes Lyme disease, which begins with a “bulls-eye” type rash and progresses into severe headache, neck stiffness, additional rashes on other areas of the body, heart palpitations, and inflammation of the brain and spinal cord. It is a very serious disease requiring lifelong medical treatment.

2. Rickettsial pathogens. This group of bacteria (found in fleas, lice, mites, and ticks that reside on rodents), is responsible for spreading typhus. There are two types of typhus: epidemic typhus, (spread by lice) and endemic typhus (transmitted by fleas). Epidemic typhus causes symptoms including: rashes on the body trunk, high fever, nausea, malaise, diarrhea, and vomiting. Epidemic typhus has similar but more severe symptoms, including bleeding into the skin, delirium, hypotension, and death.

3. Yersinia pestis. This is found in rat fleas and is the main cause for spreading plague, a deadly disease responsible for killing more than 200 million people around the world. Plague has flu-like symptoms including fever, chills, muscle pain, weakness and headache. It can progress to nausea, diarrhea and abdominal pain.

Do Rodents Carry Germs

While medical advances made these illnesses easier to diagnose and treat, rodents continue to threaten humans and animals with spread of infection. Do not attempt to remove rodents from your property without help from professional pest control experts. Until then, control the rodents’ access to food and shelter to discourage them from nesting and spreading germs and disease.
