How fast do bed bugs spread from room to room?

Bed bugs are a real nuisance when they invade your home and may become a pest control nightmare. They give you no let up as with a full-on infestation, you will struggle to sleep in peace. They feed on human blood by sucking through your skin when you are asleep. This can irritate you to a level that you might even think of abandoning your home. They can travel quite quickly and even breed at a very high rate.

To find peace and comfort when sleeping, you have to employ some way of getting rid of them before the problem becomes a disaster. Before you implement any pest control measures, you have to understand every detail concerning these pests, but we need to find out how quickly do they move around a house, from one room to another room, from apartment to apartment and from person to person

Check out the SayByeBugs Spray. Many people report it to be very effective.

Bed bug life cycle

They go through a three-stage lifecycle which is the egg, nymph, and adult. They mature fast, and the females are responsible for laying the eggs at a rate of four to seven eggs a day and usually after a blood meal. The eggs are laid in dark places at the edges of the mattress, mattresses box springs, crevices, bed cracks and a stick on any hard surfaces especially the wood. This makes them multiply fast if this furniture is moved to a different place.

The females can lay a total of 200 eggs in these isolated areas and shelters especially in dark places. The eggs will hatch within a couple of weeks and the newly formed nymphs start feeding on the spot. If the place provides a warm room temperature, the baby bugs (nymphs) mature within 14 days if they get enough food supply and up to 30 days if they don’t get the desired environment.

The nymph then shed the skin up to five times before maturing into an adult. The adults start mating immediately where the females can start laying eggs within 4 to 9 weeks if the conditions and the environment favor their growth. These annoying bugs have a lifespan of 6 to 12 months and can feed every ten days on average.

These pests can survive without a meal for a long time, and their rate of reproduction is very high thus spreading quickly through a house as they keep on searching for migration if they congest in a place.

bugs move fast across surfaces

Movement of infested furniture

Bed bugs live in beds, mattresses, furniture, clothing or spreading. If one of these infested pieces of furniture is moved, then it will carry the bugs from one room to another room, and they will continue breeding at the place where the furniture was moved if the conditions are favorable. Be extra careful when bringing any new furniture or mattresses into your house.

They can crawl

These pests are very good at crawling. Bed bugs can crawl very fast when there is dark. If you happen to feel some bites and decide to put on the light, you can’t even find one as they travel very fast at about 3 to 4 feet per minute to their hiding places. If your neighborhood is an apartment, they can spread to every home at through the cracks. If you decide to spray the infested home, it’s still possible they could move to the next room or home as they are resilient to many pesticides. This movement happens fast to the neighborhood where you may start hearing complaints of an infestation and pest control problems.

Movement of people

When people put on infested clothes, they move the bed bugs to other areas where they land. You can collect them from infested friends home and bring them home. They can also spread through traveling with infested suitcases, clothing, packaging boxes when one is moving from residence to residence. From hotel rooms to home or from schools where the cases of infestation are prevalent.

Resilience and resistance

Bed bugs are so resilient and adaptive in that they can survive for days without feeding, up to seventy days. They can live for several months if well fed. These insects are very sensitive and search their prey by following the heat from the human body and also sense the carbon dioxide from the mouth as they have a good sense of that.

When feeding, they usually pierce the human body and spit some saliva that has some chemical that reacts thus making you insensitive. The chemical is composed of anticoagulant and anesthetic that makes the victim feel nothing until the time the bugs have finished. This adds to their ability to spread fast as they may survive for long till they get another meal.

Survival and adaptation

The dark places where these insects hide during the day makes them unreachable. They can hide in the most protected areas of covered room furniture where the pesticide does not reach. When the effect of the pesticide reduces, they come out and breed again. They are clever creatures who have a good sense and may sense danger whenever they detect an anticipated move of a human and run away. It is very rare to see one, and therefore it takes a lot of time to realize your apartment building is infested especially if you are not familiar with the pest.


These pests can spread very fast because of the high rate of reproduction. They can infest a whole neighborhood and the worst things are that they may become resistant to the common pesticides. Therefore, the best thing to do if you detect a problem is to call a pest control company who can get rid of them and make them go away for good.


As you have observed, the rate at which bed bugs can move from a certain room to another room, is very high, the ability to hide in any simple object that offers some dark shelter encourages the spread. A single infestation can make your home a breeding place if don’t realize early enough. It is, therefore, necessary to take proper precautions whenever you suspect they are present. Their bite results in itching, but you only feel it when it has already attacked and left.

It leaves some stretch marks on your body which are not pleasant. To spread and fill out the entire home, it may only take some few weeks, and you will not have peace anymore. It is better if you keep your home clean and keep your staff organized making sure there is no clutter left in the rooms which can provide breeding places for infestations. If all else fails, best to call a national bug control and removal service. Discover the best bug treatment here.
