Tree pollen, which is common in early spring
Grass pollen, which is common in late spring and summer
Ragweed pollen, which is common in fall
Dust mites and cockroach droppings, which are present year-round
Dander from pets, which can be bothersome year-round but might cause worse symptoms in winter, when houses are closed up
