Living in Pasadena means being connected to LA, without too much hustle and bustle. Tree-lined streets, walkable, and peppered with people walking dogs, biking, and spending time outdoors. It’s perfect.
Until…peak mosquito season happens. Even though you enjoy mild weather all year, springtime marks the spike of buzzing, swatting, and biting. Ugh.
While many people muscle through this season, trying to enjoy outdoor spaces with relentless pest interruptions, no one actually deserves that. So, as we enter spring, it's important to plan ahead and schedule your first treatment before the pests arrive in droves.
There are several factors to keep in mind as you prepare, and that’s where Mosquito Squad of Pasadena can help. We provide a wide variety of pest treatment services to help you enjoy your outdoor spaces this spring.
Main Pasadena Pests to Worry About
There are several common pests to worry about in Pasadena when spring arrives.
- Argentine ants - They enter your home in quiet, neat lines, attracted by water and food. You think smushing one line of ants takes care of the problem, but they’ll just keep sending more scout ants. The key is to treat entry points and weak spots so they don’t enter again this season.
- Mosquitoes - Those nightly visitors are bad enough, but when day-biters (Aedes mosquitoes) interrupt your outdoor time too, it takes it to another level. And all it takes for them to populate is a bottle cap’s worth of water. So, any standing water is the perfect place for them to multiply.
- Black widow spiders - These guys love to hide out in the deep, dark areas of your garage. Alone, they lurk and spin webs, catching food. But, coming across one during your daily chores is unpleasant and, honestly, dangerous. When one bite can send you or your kids to the hospital, it’s a problem you need to tend to.
- Wasps - They love to quietly build nests in eaves and under decks. Then, before you know it, they’re swarming you every time you head outside. Annoying, territorial, and aggressive, they turn any once enjoyable outdoor space into a war zone.
- Cockroaches - When you see one resting on your wall, there’s bound to be more you can’t see. Prehistoric, gross, and fast, cockroaches come around at the least convenient times.
- Rodents - Attracted to water, food, and shelter, rodents are the worst house guests ever. Once you find their droppings near food and water and hear scratching noises at night, you definitely have a rodent issue. And usually, they can’t be removed without professional help.
Irrigation Runoff and Water Features
Water features and irrigation runoff are among the most common reasons pests populate so quickly. Too much water builds up at a low spot in your yard, and before you know it, your yard isn’t enjoyable anymore. Beautiful water fountains and other aesthetic water features are also the perfect place for pests to multiply.
So, during spring prep, make sure your water features are well-cleaned and check on them routinely. This way, fewer pests can control your yard with buzzing and biting.
Spring Cleanup
Here are a few ways you can make spring cleanup work in your favor:
- Clear brush - This ensures common pests can’t turn your brush into the perfect hiding spot to rest, repopulate, and take over your yard.
- Dump standing water - If you end up having pockets of standing water in your yard, make sure you dump and remove it from your outdoor spaces.
- Seal entry points - If pests can’t enter your home, they won’t be a problem for you.
Professional Pest Treatment Along with Regular Home Maintenance
Planning spring events and looking toward summer has you dreaming about all the outdoor activities you want to do. Maintaining your home is part of the prep, but hiring professional pest control on top of that is the most effective combination.
Handling spring clean-up is a great start, but keeping your protection from pests ongoing is taking it to the next level.
