Spider Beetle NYC: Identifying These Pests In New York

New York City is a beautiful state and is famous for its bright lights and tourist attractions, but the spider beetle NYC has become an issue for its residents.

Although these bugs are not serious pests, their fast metabolism can allow them to spread in number, which is not really a good thing for homeowners.

Let us now find out more about these NYC pests and how to control them.


What Do Spider Beetle NYC Look Like?

The spider beetle NYC looks somewhat like a bed bug with spider legs. These bugs have 6 legs, just like any regular insect.

People often mistake these insects for spiders due to the 2 extensions that they have close to their heads. These extensions resemble legs and make them look like spiders.

Spider beetles NYC have a smooth shiny protective or defensive covering as their outer shells and also have round bodies which make them resemble spiders the more.

These bugs can reach average lengths between 1.5 mm and 3.5 mm. As we mentioned earlier, they usually resemble bed bugs and this is due to their similarity in size, body shape, and even coloration.

If your NYC apartment is being attacked by these pests, the good thing is that they are not considered serious pests.

Yes, spider beetles in NYC are not really much of a threat in the home. However, the problem with them is that they grow fast in population, and hence the scouting for food sources becomes more intense.

You will often find these bugs in places where food sources are available and easily accessible, such as:

  • Restaurants
  • Eateries
  • Hotels
  • Pantries
  • Cupboards
  • Kitchens, etc.

Allowing them to thrive in these locations will only cause them to increase in population and consume the food sources in these places.

Below are a few of the possible food sources that spider beetles will feed on:

They can also be found in leather shoes and even taxidermied animals (the craft of preparing the skins of dead animals and birds and filling them with a special material to make them look as if they are alive).


What is the Lifecycle of Spider Beetles in NYC?

Spider beetles go through 4 different life stages just like any regular insects. These stages include:

  • Egg: After mating, the spider beetles lay eggs which hatch within a month after being laid.
  • Larvae: The eggs hatch into larvae and this stage lasts for about 6 to 8 months.
  • Pupa: This stage lasts for only a month and is the shortest stage in the spider beetle’s lifecycle.
  • Adult: They finally become adults after a month of living as pupae and live for a year in this adult stage.

The environment and temperature conditions of the places in which they infest are a great determinant of their reproduction rate.

The spider beetle NYC is capable of laying about 130 eggs in just a month and is even capable of laying about 2 generations of spider beetle eggs in a single year, pending on if the climate condition is favorable or not.

A favorable climate means more reproduction and more infestation. These pests usually lay their eggs in late spring or summer.
