Health Risks of a Home Infestation: What You Need to Know 2026

Mosquito extermination becomes more necessary every year. With the arrival of the tiger mosquito, enjoying outdoor spaces—especially at sunset—has become increasingly difficult. While mosquito prevention is crucial, it's equally important to recognize when natural remedies are no longer effective.

If you're considering reclaiming your garden once and for all by hiring a professional extermination company, there are key things to know to handle the process safely. What should you do during extermination? And afterward? How can you tell if you've inhaled insecticide—or if your child or pet has?

What to Do During Mosquito Extermination

If you live in the countryside, local newspapers likely announce the same news every spring: mosquito extermination is underway in parks, ditches, and public areas. For several nights starting on a specific date, it's advised to keep doors and windows closed and pets indoors. Are these precautions excessive?

Perhaps. However, it's always wise to follow expert recommendations and listen carefully to the specialized company's instructions. This makes it much easier to avoid unexpected issues later.

There's no harm in protecting the health of people and animals by adopting some seemingly drastic behaviors for a few days.

Extermination involves using a nebulizer to release substances that are generally low in toxicity but best not inhaled. As a rule, it's good practice to close windows during treatment, allowing gases and products to settle and take effect without coming into contact with you.

During Extermination: Windows and Pets

Many extermination companies agree that closing windows is necessary during procedures. If the poison might also reach your home's walls, it's wise to close shutters as well, further reducing the chance of accidental inhalation.

Closing wooden shutters or roll-downs can also help if the nebulized poison might soil glass surfaces, which would then need thorough cleaning.

Another important factor involves air conditioner use. It's advisable to turn off the AC during treatment and for the hours afterward, as instructed by the extermination company.

What's toxic to humans may not be to pets, and vice versa. If you're unsure about an insecticide, ask the company for clarification and decide what to do with your pets—they may need to be kept indoors or even relocated for a few days.

Even goldfish in a pond are included in these precautions.

Health Risks from Household Infestations

Beyond mosquito treatments, a general pest infestation in your home poses direct health risks. Pests like rodents, cockroaches, and ants can carry diseases, trigger allergies, and contaminate food sources. For instance, if you're dealing with raccoons, you might consider the best poison for raccoons, but always prioritize safety for your family and pets.

Common Health Threats from Pests

• Allergies and Asthma: Cockroach droppings and shed skin can worsen respiratory conditions.
• Disease Transmission: Rodents spread hantavirus and salmonella through urine and droppings.
• Skin Irritations: Bed bugs and fleas cause itchy bites that may lead to secondary infections.
• Food Contamination: Ants and pantry moths spoil stored goods, risking foodborne illness.

Post-Treatment Safety Measures

After extermination, wait the recommended time before re-entering treated areas. Ventilate rooms by opening windows for at least 30 minutes. Wash any exposed surfaces, especially in kitchens and bathrooms. If you suspect inhalation of chemicals—symptoms include dizziness, nausea, or difficulty breathing—seek fresh air immediately and consult a doctor.

It's best to leave during treatment and for a few hours afterward, as advised by the company. If you must stay, close all windows and doors, and avoid the treated area.

Typically, keep windows closed for 1–2 hours after treatment, but follow the exterminator's specific instructions for your safety.
