Do Spiders Feed On Bed Bugs?: The Alternative Bed Bug Exterminator

Bed bug control may be costly and has moved most people to employ or rely on the services of spiders, but do spiders feed on bed bugs?

If you are one of the people with these thoughts, you will find out in the article below that there are certain factors to be considered if you want to alternate spiders for pest control services.

What are these factors? What are the risks involved? Do spiders feed on bed bugs? Let’s now answer this question together!


Do Spiders Feed on Bed Bugs?

Yes, spiders do feed on bed bugs. However, this depends on 2 factors, which are:

  1. The size of the spider
  2. The hunting method of the spider

The big spiders may ignore the bed bugs to hunt for rather larger prey, while the smaller spiders, on the other hand, may not be able to feed on bed bugs because of their size differences.

Most people are after the idea of getting rid of bed bugs with natural enemies such as spiders, but most of these spider species may do you more harm than good, as they may even bite you in the process.

As a matter of fact, almost every spider species will bite you, so it is best to avoid them, as there are other safer ways to get rid of bed bugs.

The running crab spider is another spider that feeds on bed bugs. These spiders are yellow-brown in color and small, but do not let their small size deceive you.

Their hunting method is quite different from that of the 2 previously mentioned spiders, as they wait for their prey to come to them.

They will usually lurk behind trees and plants and pounce on unsuspecting insects that pass by.  Their speed is their ultimate advantage.

  • Yellow Sac Spiders:

You will often find them hiding under the furniture or under leaves or stones, awaiting unsuspecting prey.

  • Cobweb Spiders:

Even though these spiders will help eliminate your bed bug problem, they are poisonous, and you may have to deal with them later on.
