What makes a bed bug happy?

Bed bugs need certain conditions to be able to get to each stage of their life cycle and reproduce.  The bed bug life cycle was covered off in my last blog post below.

Good conditions are as follows:

  • Ability to feed
  • Warm temperature between 18 C and 30 C
  • Relative humidity

If the conditions above are not available, especially if the temperature drops below 18C, then the bed bug’s life cycle will take longer and they may go into diapause. When bed bug activity slows down, people can often mistakenly think that the bed bugs have gone. Unfortunately they are still there but just working at a much slower rate. The number of days between a feed will expand beyond the usual feeding cycle and females may only be lay 2-3 eggs a day.

When the right conditions for bed bugs aren’t met – they will do one of three things:

  • Go in search of a food source using their sensors to find Carbon Dioxide
    This is when they are likely to travel into other rooms or to the neigh-bouring property
  • Some bed bugs who have not reached maturity will die in this situation
  • Stronger adult bed bugs will go into diapause
    This is a form of hibernation for up to 18 months and is very bad news for anyone suffering with an infestation.  I will cover off more about diapause later.
