How Cockroaches Travel and Spread from One Home to Another
Cockroaches are notorious pests that can quickly infest a home. Understanding how cockroaches travel and spread can help you prevent and control an infestation. A study in the Journal of Economic Entomology found that up to 40% of roach infestations in new apartments originated from infested buildings nearby.
Cockroaches are adept at moving from home to home and spreading throughout living spaces. Their ability to squeeze into tight spaces and survive without food or water allows them to hide in belongings and popup in new homes.
This article covers the key things regarding this commonly asked question “Can Cockroaches Travel From House to House?” which you need to know about cockroaches spread, including signs of an infestation, how they travel between homes, and steps to prevent bringing roaches home. Read on to protect your house from these persistent pests!
What are the Signs of a Cockroach Infestation?
Noticing signs of cockroaches early is key to controlling an infestation before it gets out of hand. Be on the lookout for:
Roach droppings: Small, dark brown or black pellet-like droppings indicate roaches. Droppings mean they have been there a while.
Empty egg cases: Spotting empty tan-colored egg cases means roaches have hatched in the area. Each case held up to 50 baby roaches.
Cockroach bodies: Seeing live or dead roaches is an obvious red flag. Just one roach likely means many more hiding.
Odd odor: Roaches emit a musty odor caused by the secretion they use to communicate. Where there’s a smell, there’s bugs.
If you spot any of these signs, you likely have cockroaches and should take action. Ignoring early warnings allows the population to multiply rapidly.
Can Cockroaches Travel From House to House?
Cockroaches such as Germán cockroach and Americans cockroach both can easily travel between homes. Studies by the University of Florida have shown that German cockroaches can cover over 15 meters in a single night, allowing them to readily explore multiple houses in search of resources in a variety of ways:
Through drains & pipes
Roaches use linked drain/plumbing systems to move between units in an apartment building or duplex homes. Studies by the National Center for Biotechnology Information have shown that German cockroaches can survive submerged for over 30 minutes, making them adept at navigating through wet environments like drains.
Along wires & pipes
Roaches crawl along wires and pipes running between walls or ceilings of adjoining buildings.
Hitchhiking in boxes or bags
Roaches hide in cardboard boxes, grocery bags, purses, backpacks or other belongings when transported. Cockroaches can unintentionally be transported on clothing, shoes, or even grocery bags. Research by the International Journal of Pest Control has shown that cockroach eggs can be easily transferred on human clothing, potentially establishing new infestations in new locations.
On Used Appliances or Furniture
Buying or inheriting an infested item introduces roaches. Inspect carefully and treat used items.
Understanding how cockroaches infiltrate homes helps you prevent bringing roaches home when moving.
How can Roaches Come into My House or Apartment?
Cockroaches easily find ways to enter any house or apartment. Possible entry points include:
- Cracks around doors, windows or foundations
- Gaps around pipes, wires or vents
- Open windows or doors
- Hitched a ride in boxes, grocery bags or other items
- Moved in on used furniture or appliances
Once inside, roaches make themselves at home in dark, warm and moist areas with available food and water. Kitchens and bathrooms suit them perfectly. A study in the journal Urban Ecosystems revealed that American cockroaches can fit through gaps as small as 1.5 millimeters, making it easy for them to enter new houses through even seemingly insignificant cracks.
Where do Cockroaches Spread and Hide in a Home?
Cockroaches multiply and spread rapidly once established in your home. Possible hiding and breeding spots include:
- Kitchen cabinets & pantries
- Behind or under appliances
- Inside walls or ceiling voids
- Furniture cracks & crevices
- Microwaves & small appliances
- Bathroom vanities & plumbing
- Attics, basements & crawl spaces
Female roaches produce 20-50 eggs per egg case and may drop several over their lifetime. Numbers multiply exponentially in just months.
How Can I Prevent Bringing Roaches Into My Home?
You can prevent hitchhiking roaches by taking precautions when moving:
Inspect & treat furniture before moving it: Check for signs of roaches and thoroughly treat any infested items with insecticide before loading.
Pack belongings in plastic bins: Use clear plastic bins rather than cardboard boxes, so roaches have nowhere to hide.
Carefully unpack & inspect items: Unpack slowly and thoroughly inspect each item for roaches before bringing inside.
Inspect appliances before use: Major hiding spots for roaches. Carefully inspect the interior and exterior before plugging them in.
Call pest control about previous issues: If the old place had roaches, call pest control to treat before moving items.
Following these tips stops roaches from thumbing a ride along with your stuff to your nice, new home. Additionally you can explore more detailed article regarding prevention tips that will prevent roaches from visiting a house.
What Makes Cockroaches so Good at Spreading?
Cockroaches are perfectly designed to infiltrate our homes and multiply by the thousands:
Flat bodies: Allows them to squeeze through incredibly small cracks and crevices.
No need for food/water for weeks: Enables them to survive while traveling or hiding.
Rapid reproduction: Females produce up to 50 offspring every couple months.
Nocturnal: They come out at night to feed, rarely seen.
Vast mobility: Crawl up walls, under doors, through drains – you name it.
These physical traits equip roaches to spread widely and be extremely effective home invaders.
How Can I Stop Roaches Moving In from a Neighbor?
Since roaches easily spread between adjoining buildings, an infested neighbor can introduce roaches. Here is how to protect your home:
Inspect for entry points: Seal any cracks or gaps where pipes, wires or vents enter from problem units.
Install door sweeps: Door sweeps or draft blockers prevent roaches entering under doors.
Set traps: Place sticky traps or roach bait stations around entry points and susceptible areas to catch scout roaches.
Speak to building manager: Discuss the issue with neighbors and building management. Coordinate pest control treatment if necessary.
With diligence, you can keep neighborly roaches from becoming permanent, unwanted housemates.
