Pest control chemicals—ranging from insecticides and herbicides to rodenticides and fungicides—are widely used in agriculture, public health, and homes to protect crops, reduce disease vectors, and prevent property damage. While these products can deliver clear short-term benefits, they also carry environmental costs that are often diffuse and long-lasting. Understanding those costs requires looking beyond immediate…

As homeowners look for safer, low-chemical options to manage insects, ultraviolet (UV) light devices — from “bug zappers” and sticky glue traps that use blacklight to attract flying insects to UV-C sterilizers used for microbes — have become a familiar presence. But “UV pest control” is not a single technology: different wavelengths and device designs…

Choosing a herbicide isn’t just about what kills the weeds fastest — it’s about balancing effectiveness with long‑term safety for people, pets, pollinators, wildlife and water resources. “Safest” in this context means products and practices that minimize non‑target harm, break down quickly in the environment, have low mobility and bioaccumulation potential, and are formulated and…

Choosing a pest control provider when you share your home with pets requires more than a quick online search. Pets are curious by nature, often sniffing and licking surfaces or hunting insects and rodents, which increases their risk of accidental pesticide exposure. At the same time, pests themselves can threaten pet health—fleas, ticks, rodents, and…

Pesticides are chemical or biological agents designed to control unwanted insects, rodents, fungi and other pests. Around the home they’re used to protect gardens, lawns, and living spaces from damage and disease. Used judiciously, they can be a useful tool; overused, however, they create a range of interconnected problems that affect human health, pets, the…

Peppermint oil has become a popular, plant-based alternative for people looking to repel household pests without relying on synthetic pesticides. Extracted from Mentha x piperita, the oil is rich in aromatic compounds such as menthol and menthone that irritate insects’ and rodents’ chemosensory systems. That strong scent makes peppermint oil useful against a range of…

Pest problems in rental properties present a double challenge: they need to be resolved reliably and quickly, but treatments must also protect tenants, pets and the property’s reputation. Increasingly, landlords and property managers are turning away from broad-spectrum chemical spraying and toward non-toxic or low-toxicity strategies that prioritize exclusion, sanitation and targeted controls. These approaches…

Mosquitoes are more than an annoyance: they transmit diseases (dengue, Zika, malaria, West Nile, etc.) and make outdoor and indoor life uncomfortable. Because of that, consumers and public-health programs use a wide range of tools to reduce mosquito bites. Two broad categories of electronic repellents dominate the market: battery-powered (portable) devices and plug-in (mains-powered) units….

Gardening close to home brings the dual joys of fresh produce and time outdoors, but it also raises practical concerns about ticks — tiny parasites that can transmit serious illnesses. When choosing how to reduce tick populations near a vegetable garden, safety for people, pets, pollinators, and the edible crop itself must be the top…

Pest populations — from aphids chewing garden leaves to rodents gnawing stored grain — are a constant challenge for farmers, gardeners and public-health managers. Natural predators, however, provide a powerful and often underappreciated line of defense. These predators include insects (lady beetles, lacewings, predatory mites), parasitoids (many tiny wasps), birds, bats, amphibians, reptiles and small…
