If you’ve discovered bed bugs in your home, you may be worried about them infesting beloved stuffed animals. Understanding how long they can survive without a blood meal is key to protecting your possessions.

If you’re short on time, here’s a quick answer to your question: bed bugs can live over a year without feeding on stuffed animals due to their resilience and ability to enter a dormant state when necessary.

In this comprehensive guide, we will cover everything you need to know about the bed bug life cycle, how long they can live on various surfaces, and what temperature extremes or chemical treatments can kill them.

The Bed Bug Life Cycle and Habits

Eggs and Hatch Time

A female bed bug can lay up to 500 eggs over her lifetime. The eggs are tiny, about the size of a speck of dust, and are laid in cracks and crevices where they are hidden. The eggs hatch in around 10 days. The hatch time can be longer if temperatures are cooler.

Nymph Stages

After hatching, bed bugs go through 5 nymph stages, each one an immature form that must feed on blood before molting to the next stage. The whole nymph phase lasts around a month. Nymphs look much like small versions of the adult bed bug. They are often even harder to see with the naked eye.

Adults and Mating

Once bed bugs reach the adult stage, they are about the size of an apple seed. Adults can live over 12 months and will try to feed every 3-5 days if a host is available. Females give off a pheromone scent to attract males and mating usually happens quickly after the female’s first blood meal.

Feeding and Hosts

Bed bugs feed on blood, usually at night when hosts are sleeping. Their preferred hosts are humans, but they will also bite other mammals and warm-blooded animals. They use their long proboscis to pierce the skin and draw blood for about 5-10 minutes.

According to the CDC, around 80-90% of people will develop an itchy welt or rash from a bed bug bite.

Hiding Places

During the day, bed bugs like to hide in dark, narrow spaces close to where their hosts sleep or rest. Some common hiding spots include:

  • Cracks and crevices in bed frames and mattresses
  • Behind headboards, electrical outlets, and picture frames
  • Inside box springs, bedding, furniture, curtains, and clutter

Bed bugs are expert hitchhikers and can easily be transported between locations in luggage, purses, furniture, clothing and more. This allows them to infest new places rapidly. Careful inspection and prevention methods are vital to control bed bug spread.

Bed Bug Survival Without Feeding

Blood Meal Importance

Blood meals are extremely vital for bed bugs’ survival and development. Adult bed bugs can survive between 2 to 10 months without a blood meal, depending on environmental conditions like temperature and humidity. However, they need regular blood meals to reproduce and progress through growth stages.

Entering Dormancy

When bed bugs are starved of blood meals, they enter a dormant state known as diapause to conserve energy. In this state, the bed bugs reduce their metabolism and activity levels to a bare minimum. They can survive up to a year in diapause while waiting for a host to feed on before reactivating to seek blood meals again.

Living Without a Host

Bed bugs are nest parasites – they prefer living in close proximity to their hosts. However, when hosts are unavailable, bed bugs can still survive for extended periods by hiding in dark, secluded areas like:

  • Cracks and crevices in walls, floors, furniture etc.
  • Inside mattresses, bed frames, couches, and other upholstered furniture
  • Inside stuffed toys, shoes, purses, luggage, and backpacks

These areas provide shelter and regulate stable temperatures to support bed bug survival. Stuffed animals with fabric crevices make very suitable harborage sites when human hosts are absent.

Temperature and Humidity Tolerance

Bed bugs fare best in temperatures between 70-80°F and in higher humidity levels. However, they can tolerate a wider temperature range of 55-95°F at different life stages. Below or above this range can negatively impact their growth, reproduction and ability to survive without blood meals.

A summary of bed bugs’ temperature and humidity tolerance is outlined below:

Temperature Range Survival Period
41-46°F Up to 2 months
55°F 2-6 months
70-80°F (Ideal) 12+ months

At lower temperatures, bed bugs enter diapause. Higher temperatures above 95°F can kill bed bugs quicker without blood meals. Similarly, bugs survive longer in humidities >50% compared to dry conditions.

So in stuffed animals, bed bugs can potentially survive up to a year or longer depending on ambient temperatures and humidity levels.

Killing Bed Bugs on Stuffed Animals

Laundering and Drying

One of the most effective ways to kill bed bugs on stuffed animals is to wash and dry them. Stuffed animals can be laundered in hot water temperatures between 113-140°F and then dried on the highest heat setting for at least 30 minutes.

The combination of high heat in the washer followed by sustained heat in the dryer is lethal for all stages of bed bugs, including eggs.

According to entomology experts at the University of Minnesota, drying items at temperatures above 120°F is an extremely effective way to kill bed bugs because they cannot tolerate such high heat.1 Just be sure to check the care label on your stuffed animal first to verify that it can withstand hot washer and dryer temperatures.

Heating Treatment

If the stuffed animal is not washer/dryer safe, heat treatments are another good option. This involves using a heating unit or clothes steamer to raise the internal temperature of items to lethal levels for bed bugs.

Temperatures of 120°F for at least 20 minutes have been shown to kill all stages of bed bugs.

The benefit of using targeted heating methods like a clothes steamer is that they can kill bed bugs without having to wash the stuffed animal. Just be sure to carefully run the steamer over all outer surfaces, seams, and crevices.2 The direct contact with concentrated steam heat will take care of any bed bugs or eggs hiding out.

Freezing Temperatures

Exposing stuffed animals to freezing temperatures can also do the trick. Research shows that freezing items for 4-7 days at temperatures below 32°F will kill bed bugs and eggs.3 This prolonged exposure to freezing conditions is cold enough to cause injury to cells and internal structures.

Just check to make sure the stuffed animal can safely withstand the cold before tossing it in the freezer. And be sure it is sealed in bags so that condensation does not build up inside the freezing environment, leading to potential mold issues.

Chemical Sprays

There are also chemical sprays registered by the EPA specifically for killing bed bugs. These residual sprays contain ingredients like pyrethroids that are designed to kill bed bugs on contact. Some popular OTC brands are Bedlam Plus, Steri-Fab, and Harris Bed Bug Killer.

Be extremely careful when using chemical sprays on stuffed animals, as they could be toxic. It’s best to spot test a small inconspicuous area first before spraying the entire surface. And make sure to thoroughly ventilate the stuffed animal after application.

As much as possible, relying on non-chemical treatment methods is best for stuffed animals and plush toys where residues could transfer to human skin.


While bed bugs can live over a year dormant on stuffed animals, proactive laundering, heating, freezing, or chemical treatments can kill all stages. Understanding their resilience equips you to take control and protect beloved belongings.

With vigilance and preventative measures, you can rest assured snuggling up safely with your furry friends.
