If you’re considering calling pest control experts, you might be wondering, will rain affect pest control treatment? The answer is that’s not always the case. Sometimes, the rain will have minimal to zero impact on pest control treatment. The rain can also be detrimental to the treatment as it can wash away the chemicals and make it ineffective. 


At other times, pesticide applications can be more effective when it’s raining.

Treating Internal And External Areas

Treating Internal And External Areas

There’s no reason to be concerned about the effectiveness of pest control treatments, especially if your property is mostly protected against rain. If your house has eaves and gutters, most of the rain that falls onto the roof will travel down through this path before getting released through the designated outlets. In this case, pest control treatment can be applied through the dry walls.


Other than that, most pesticides applied outside the home are done close to the foundation, which is typically covered by an overhang structure that keeps the area dry. 


Experienced pest control experts will know to apply treatment close to the property’s perimeter, which is protected from rainfall. In addition to this, pest control treatment will be applied around cracks, door frames, and windows, which are often safe from the rain.


If you have a pest problem indoors, there’s no problem because it can still be treated, even when it’s raining hard. This is unless you have problems with moisture accumulation, which should be addressed first. 


Pest Treatments Used

Some pest treatments are formulated with bonding agents, making them stick to the surface they’re applied in. After application, the treatment forms an insoluble barrier that will be unaffected by a little rain. 


In order to be effective, there are pest control treatments that should only be applied on dry surfaces, as this allows the treatment to bind effectively. So long as the surface isn’t wet when the treatment is applied, once dry, it will be resistant to wash-off when there’s a rain shower.


Did you know that some outdoor treatments are often available in granular form, which needs water to become effective? When there is rain, the granules are carried down to the soil and work effectively on eliminating pests that lurk in the area. 


Improving Pest Control Efforts

Improving Pest Control Efforts

Depending on the type of pest infestation you are dealing with, the rain can also improve pest control treatments. Certain pests such as mosquitoes and termite colonies thrive during the rainy season. However, there are also pests that don’t like rain. While water is essential for survival, pests such as cockroaches, spiders, rodents, and ants will crawl out of their underground homes to avoid the rain and protect their colonies. 


Once these pests are drawn out during the rain, they will nest in your home. 


Depending on the type of pest infestation, it can sometimes be easier for pest control teams to search for nests and administer the treatment. 

Severity of The Rain

Severity of The Rain

While in most cases, pest control treatment won’t be affected by the rain, a professional pest control team will always consider the situation before continuing with the treatment. While a bit of rain is not an issue, severe rains and winds can become a problem.


In severe weather, the strong winds can blow the spray into off-target areas, which could cause unintended effects during the application. Strong rains during and immediately after the application can wash the treatment off and take it to other areas. 


Your safety will always be considered first before a pest control expert will begin the treatment. If needed, the treatment will be rescheduled to prioritize safety. 


Key Takeaway

Will rain affect pest control treatment? This question is understandable, given that you want the treatment to be effective and provide value for your money. The good news is, that a bit of rain is never a problem, especially if your property is protected from rainfall. Some pest treatments, when applied properly, can withstand a little rain. There are even pest control treatments that require water to be most effective! Some pests go out of hiding during the rain, which can make pest control treatments more efficient. 


If the weather is really severe, pest control experts will advise the best course of treatment.
