blacklegged ticks
The lifecycle of blacklegged ticks (Ixodes scapularis and Ixodes pacificus) generally lasts two years. During this time, they go through four life stages: egg, six-legged larva, eight-legged nymph, and adult. After the eggs hatch, the ticks must have a blood meal at every stage to survive.

Can spiders spread Lyme disease?
These small, spider-like arachnids feed off the blood of humans and animals. “Sometimes they pass along Borrelia burgdorferi, which is the bacteria that causes Lyme disease,” says Nathan Hofmann, FNP.
Do nymphs carry Lyme disease?
If already infected, nymphs can transmit Lyme disease to their new host, or nymphs may become infected with a tick-borne disease by feeding on an infected reservoir host, or even contract a second tick-borne disease making them co-infected with various pathogens.

What are the odds of getting Lyme disease from a tick?

How long does a tick have to be attached to transmit disease?
Even if a tick is attached, it must have taken a blood meal to transmit Lyme disease. At least 36 to 48 hours of feeding is typically required for a tick to have fed and then transmit the bacterium that causes Lyme disease. After this amount of time, the tick will be engorged (full of blood).
Do foxes carry Lyme disease?
The hedgehog tick and fox tick also carry and transmit Lyme disease so, wherever there are hedgehogs or foxes, there is a risk of Lyme disease: in overgrown urban gardens and town parks alike.
Can rabbits get Lyme disease?
We conclude that rabbits perpetuate the agent of Lyme disease in an enzootic cycle where rabbit-feeding Ixodes are abundant, that intensity of transmission is independent of the zoonotic cycle in mice, but that infection may occasionally be exchanged between these cycles.
Do Coyotes get Lyme disease?
Coyotes are incompetent reservoirs of Lyme Disease. Foxes are also incompetent reservoirs of Lyme Disease. Foxes provide a benefit when it comes to Lyme Disease because they are predators of white-footed mice reducing their numbers.
