Why Rain Brings Out Pests
June 29, 2020
Fun fact: that distinct odor that you smell right before rainfall is called “petrichor”. As July approaches, we’re inching closer and closer to the wettest time of the year around here, which means a whole lot of petrichor in the near future. While a nice rainfall might mean a temporary relief from muggy temperatures, it doesn’t just bring about that distinct smell; it also brings out a specific set of pests that seem to thrive in a post-rain environment. But why do some pests view a rainy day as an opportunity, while others stay sheltered? We have some answers.
Why Rain Brings Out Pests
There are a few reasons that you see specific insects after (or even during) a rainstorm. One of them is mosquitoes. So how are mosquitoes able to survive unsheltered in rain, even though they are airborne? It has to do with their size! Because mosquitoes are somewhat tiny, they are less likely to be hit with a raindrop, which allows them to keep flying, even in the rain. With other predator insects and mammals taking shelter during rain, mosquitoes are able to feed without fear of competition or other predators.
Some insects are also drawn to moisture and standing water that comes after a rainstorm. Mosquitoes and termites especially thrive in moist, humid environments, and the humidity levels after a storm create just that environment. On the other hand, other insects like ants and subterranean termites will become active during and in the aftermath of a storm when heavy rain floods the underground tunnels where they live. Whether it’s because of preferable weather conditions or to seek shelter, you can be sure when the rain starts, some of these insects will become more active.
Pests That Come Indoors During Rainfall
Most pests, unlike the ones we talked about above, look for shelter during storms. This can become a problem especially when these insects have their nests damaged, which can cause them to start swarming. The target? Your home. Some insects and wildlife that might look to enter your home during and after a storm include:
Protecting Your Property From Pests During Spring
So now you’re worried about swarms of insects taking over your lawn and a family of squirrels clawing their way into your home on rainy days. So what can you do to prevent that from happening? There are a few preventative measures that you can take to help protect your home from pests.
- Keep things clean and tidy- Limit the spaces that an insect or animal can take shelter in during a storm. This means keeping a tidy lawn, making sure plants and bushes are well-trimmed, and organizing any clutter in garages, basements, and attics.
- Clear out standing water- Try to clear out any standing water on your property. Standing water can act as an insect magnet and breeding ground, so the less standing water you have around your home, the better.
- Seal cracks and holes in your home- Pests don’t usually come into a home through the front door--they’re sneaky like that. Cracks or holes in walls, ceilings, and foundations can be an attractant to pests when the rain starts and they need to find shelter quickly. Seal the entry points that you can, and you’ll be a whole lot better off.
- Keep trash tightly secured- Accessible trash will is appealing to almost any pest, and if your home has a trash can they can get into easily, it makes the interior of your house and the surrounding property all the more appealing, even during a rainstorm.
- Contact A-1 Pest Control- Even with the best attempts, there’s always a chance that one pest or another will find its way onto your property or even into your home. That’s where we come in.
