Bugs are common critters that invade residential and commercial buildings. This usually results in property owners purchasing temporary solutions like sprays, physical barriers, and natural repellents like peppermint oil. While this proactive approach is commendable, professional pest control in San Diego provides long-lasting results. At Wheeler’s Pest Control, we understand how frustrating frequent pest invasions can be and provide tailored solutions to keep bugs at bay year-round. Our technicians also schedule follow-up inspections to keep your living spaces pest-free and safe all year round.

The Reasons for More Bugs After Pest Control

If you hire a pest service provider to eliminate bugs and notice these critters after a few days, don’t be frustrated. This is a completely normal occurrence, especially if the treatment needs time to kick in. Let’s explore the reasons you’re still seeing bug activity after a professional pest removal service.

It’s Your First Pest Control Treatment

When dealing with a full-blown infestation, one treatment may not be enough to permanently resolve the problem. The first treatment is usually designed to flush out critters from hiding, whether it is spiders, ants, or cockroaches. Additionally, some treatments are specifically designed to work slowly, which means they take more time to spread and are more effective in the long run. According to pest service providers and industry experts, it takes at least three treatments to effectively address the problem.

Uninterrupted Life Cycle

Trained pest removal experts understand the life cycles of different critters, ensuring the correct timing to achieve the desired results. If you treat breeding grounds during the egg stage, then you may be dealing with an infestation in the future. Eggs are usually immune to treatments, meaning you have to time treatments correctly to prevent more bugs after treatment. A reputable pest removal company can schedule follow-up treatments based on the type of pest and its life cycle. This plays a crucial role in breaking the cycle and preventing infestations down the line.

Weather

Pest behavior changes with the weather. As we approach the colder months, bug activity is likely to decrease. However, this doesn’t mean you are safe, since pests can seek refuge indoors, taking over your living spaces. Conversely, warmer temperatures encourage pest activity, leading to more frequent sightings after treatment. Additionally, wet conditions provide moisture that promotes reproduction, so be on the lookout when it rains. A licensed exterminator can devise a tailored pest removal plan that accounts for weather changes to keep your home or business safe throughout.

Water or Food Sources

Another reason you may detect bugs after a professional pest service is the availability of food, water, and other attractants. As mentioned, moisture promotes reproduction. If you leave exposed water or spills, bugs will constantly invade your spaces. Also, food sources like crumbs, dirty dishes, takeout boxes, and full trash bins can make your home a target for bugs, even after pest control treatment. By vacuuming floors, cleaning surfaces, and practicing good disposal habits, you can enjoy pest-free spaces longer after professional treatment.

How Long After Treatment Do Bugs Die?

If it is your first treatment, then chances are you will see bugs sooner. Also, properties that don’t receive regular preventive treatments can experience critters being flushed out. A licensed and certified pest service uses proven products that take longer to kill bugs, ensuring the entire colony is exterminated after a few days or a week. The general rule of thumb is that pest sightings 10 days after a treatment indicate the need for more intervention by the pest control company.
