Pest Guide Weather Advice   

Whether conditions in central and western Florida can be hot and humid, cool and dry, or rainy with sudden downpours and this will directly affect pests and their activities. These conditions prompt pests to invade your premises or building to seek three very basic needs – food, water and shelter. Find out how our local weather is affecting your pest forecast this season, and then use our tips to assist you in maintaining a pest free environment.

Rainy, Wet Weather 

Pest Forecast: More pests may invade your environment. 

You can expect an increase in the number of pests you see during our rainy season, plus more invasions, as these larger populations seek food. Specific pests you should watch for include: ants, outdoor cockroaches, spiders, crickets, ladybugs, yellow jackets, hornets, mice and rats. Now here’s why: 

  • More moisture promotes pest reproduction and growth, so you have more insects! Ants, especially, reproduce in greater numbers in wet, warm climates. 
  • Additional pests mean a greater need for more food sources. Insects will continue to search beyond their normal habitats to find food. 
  • Invasions may occur as pests relocate to drier ground.



Excessive Rainfall and Flooding 

Pest Forecast: Ants and others retreat from flooded soil.

Excessive rainfall over a short period of time will flood the soil and cause insects, especially ants, to seek dry ground. Some pests retreating from the unfavorable weather conditions will find shelter in the nearest location, which is often your building or warehouse. Other facts to note: 

  • Ants can easily move an entire colony on short notice. 
  • Common areas that may become new homes overnight for ants are wall voids and under foundations. 
  • Excessive rain creates an abundance of ants, which increases the need for pest control services.


Dry Conditions 

Pest Forecast: Pests most likely will seek water in and around your building.

Rain will create additional pest growth, while lack of rain promotes pest invasions. When we enjoy a dry, cooler spring, chances are pests may be fewer, but they will be relentless in their pursuit of moisture for survival. Dry conditions affect pests in the following ways:

  • Lack of moisture outside drives pests inside buildings to find water. 
  • During dry weather ants, earwigs, millipedes, pillbugs and sowbugs, crickets and spiders are the most common pests to seek water indoors. 

Millipedes have been known to leave leaf litter, mulch or a lawn and move in migrations of thousands when their harborages dry out – inevitably invading buildings that stand in their way.


Extreme Drought 

Pest Forecast: Fewer pests but more frequent visits.

Fewer pests are one benefit of a dryer spring and summer. Extended periods of dry weather or droughts will affect the food supply also eliminating some insects. Here's what you can expect: 

  • With a reduced food supply, scorpions & certain spiders must venture beyond their normal habitats in search of a food source. 
  • Pests may establish breeding sites and harborages in and around your building  – in debris, bricks, rocks, firewood, etc.


Cool Weather 

Pest Forecast: Warmth indoors attracts pests into your living spaces. 

With cooler temperatures outside, pests seek the warmth and shelter of your building. Some pests you are likely to find invading your home to escape the cooler temperatures are box elder bugs, cluster flies, lady bugs, and silverfish. Here’s more about these pests: 

  • Occasional invaders, like overwintering pests, start moving indoors during late summer and early fall as the temperature drops. 
  • These pests like to use walls, voids and attics as their winter retreats. 
  • There isn’t any way to totally pest-proof your building, but you can seal as many cracks and holes on the outside of your home as possible, especially on the south and west walls where the sun heats the home during the late summer and fall. Also, you should install tight-fitting screens on all foundation and attic vents. 

Any short period of drought, extended rainfall or excessive heat or cold can force insects and other pests to invade buildings seeking relief from unfavorable weather conditions. Like people, pests are affected by extreme heat or lack of rain and will do what is necessary to survive. Understanding the cause-and-effect relationship of weather and pests will help keep insects out of your home.
