The most effective summer pest prevention removes what ants, mosquitoes and wasps come for: keep food sealed and ant entry points closed, empty standing water every week so mosquitoes can’t breed, and keep garbage, drinks and pet food covered so wasps don’t forage near your house. Add window screens, repellent when you’re outdoors and a spring check for new wasp nests, and most summer pest problems stay small. Saela Pest Control is a residential and commercial pest control company that treats all three of these summer pests.
This guide covers each pest in turn, then the home checks, kitchen habits and professional help that tie prevention together.
Why Ants, Mosquitoes and Wasps Increase in Summer
Each of these pests becomes more noticeable in summer for its own reason. Ants move indoors looking for food, water and relief from the weather, mosquitoes breed in water that collects around the yard, and wasp colonies grow larger as the season goes on.
UC IPM’s guide to ants notes that ants often enter buildings seeking food and water, warmth and shelter, or refuge from dry, hot weather or flooded conditions. The CDC notes that mosquitoes lay eggs near water, so rain and irrigation that leave water standing in containers give them places to breed.
Wasps follow a seasonal cycle too. UC IPM explains that yellowjacket workers hunt mainly for protein while the nest is growing, then, by late summer, need large amounts of sugar and turn up wherever sweet food is available, which is why prevention works best when it starts in spring.
Ant Prevention Strategies
Identifying Common House Ants
Identifying the ant comes first, because different species nest and feed in different places. UC IPM lists the Argentine ant, odorous house ant, pavement ant and carpenter ants among the most common ants that invade homes in California, and the mix varies by region.
Carpenter ants nest in wood, so they call for a different approach than small ants that forage for sweets and grease in the kitchen. Saela’s ant control page explains how treatment starts with identification.
Eliminating Food Sources
Taking away food is the first line of defense, because foraging ants follow trails to whatever they find and recruit others to it. Wiping up visible ants with soapy water also removes the trail they use to recruit more foragers, according to UC IPM.
Store food, including pet food, in clean, sealed containers rather than plastic bags or open packaging, as UC IPM advises. Clean up crumbs, grease and spills, and pay attention to areas under appliances and inside cabinets.
Sealing Entry Points
Closing the gaps ants use to get in reduces how many reach the kitchen in the first place. UC IPM recommends sealing entry points with caulk and trimming vegetation away from the foundation. Follow an ant trail back to where it enters the house, then seal that spot first. Start with these spots:
- Cracks and crevices in exterior walls, the foundation and siding
- Gaps around windows, doors and the places where utility lines enter
- Worn weather stripping and door sweeps
Low-Toxicity Ant Control
The lowest-toxicity steps are cleaning and sealing, and they are also the ones that keep working. Wiping trails with soapy water removes the scent ants follow, and sealed food storage leaves them little reason to return. Together with sealed entry points, these are the steps to try before reaching for any insecticide.
If ants keep coming back, UC IPM explains that sprays only kill the foraging ants, while baits are a key tool because workers carry small portions back to the nest. Our article on why ants keep coming back looks at this in more detail, and any product should be used as its label directs.
Mosquito Control Measures
Eliminating Standing Water
Removing standing water is the most important mosquito prevention step, because mosquitoes lay their eggs near water. The CDC’s guide to mosquito control at home recommends doing this once a week. Even small containers count, so walk the whole yard, including toys, plant saucers and covers that sag and hold water.
The CDC advises that you empty and scrub, turn over, cover or throw out items that hold water, such as tires, buckets, planters, toys, pools, birdbaths, flowerpot saucers and trash containers. Clean gutters so they drain, and look for low spots in the yard where water sits after rain or irrigation.
Landscape Management for Mosquito Prevention
Yard care helps most when it removes the shaded, sheltered places where adult mosquitoes rest. Keep grass mowed and shrubs trimmed, and check under decks and porches, where shade and moisture collect. Thinning dense plantings near patios also lets air and light into the spots mosquitoes use during the day.
Don’t count on plants to do the job. UF/IFAS Extension explains that plants such as citronella, lavender and marigolds contain oils that can deter mosquitoes, but those oils have to be extracted and concentrated to work, so planting them gives minimal protection.
Personal Protection Strategies
Some mosquito bites are hard to avoid in summer, so personal protection is the second layer after removing standing water. The CDC’s mosquito bite prevention guidance recommends EPA-registered insect repellents with DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol or 2-undecanone.
The CDC also recommends loose-fitting, long-sleeved shirts and pants, and clothing and gear treated with permethrin. Permethrin is for clothing and gear only; the CDC says not to use permethrin products directly on skin.
Outdoor Living Space Solutions
Screens are the simplest way to keep mosquitoes out of living spaces. The CDC recommends using screens on windows and doors and repairing holes so mosquitoes stay outdoors, and using air conditioning when possible. Screened porches give you an outdoor space that mosquitoes can’t easily reach.
For larger yards or persistent problems, professional treatment can target where adult mosquitoes rest. Saela’s mosquito control mist treatments target resting sites such as shaded foliage and areas beneath porches, and its mosquito-control guidance includes reducing standing water around the property.
Wasp Management Techniques
Identifying Common Wasp Species
Yellowjackets, paper wasps and bald-faced hornets are the wasps homeowners usually notice in summer, and each nests differently. UC IPM’s guide to yellowjackets and other social wasps notes that yellowjackets often nest in rodent burrows but sometimes choose wall and ceiling voids, while paper wasps hang open, umbrella-shaped nests under eaves, in attics or under branches. Bald-faced hornets, which Penn State Extension describes as aerial yellowjackets, build gray, football-shaped nests.
Identification matters because the risk differs. UC IPM notes that paper wasps are rarely aggressive, while yellowjackets defend their nests, so our overview of common wasp species is a good place to start if you are not sure what you are seeing.
Preventing Nest Establishment
Spring is the best time to prevent wasp problems, because overwintered queens start new nests when the weather warms. UC IPM notes that knocking down a newly started paper wasp nest early in the season usually makes the founding female go elsewhere.
Check eaves, sheds, attics, deck railings and play equipment every few weeks in spring and early summer. Seal gaps in siding and eaves before queens look for nest sites, and have any nest near a door or walkway identified while it is still small.
Safe Wasp Nest Removal
Leave established nests to a professional, especially yellowjacket nests in the ground or in walls. UC IPM states that if a nest must be eliminated, it is easiest and safest to call for professional help, and it warns that wasps will attack if they sense a poison being applied to their nests.
UC IPM also notes that underground nests can be quite a distance from the visible entrance, so store-bought spray may not reach the wasps. Saela’s yellowjacket control and hornet control pages explain what professional treatment of these nests involves.
Creating Wasp-Free Zones
You can’t keep every wasp out of a yard, but you can make eating areas much less attractive by taking away the food scavenging wasps look for in late summer. Scavenging wasps usually won’t become a problem if there is no food around to attract them, UC IPM explains.
Keep food and pet food covered or indoors, keep garbage in sealed cans and empty them regularly, and pick up ripe fruit, as UC IPM advises. It also notes that yellow lure traps hung along the perimeter of a property can reduce foraging by some species around patios and picnic areas.
Integrated Pest Management for Summer
Comprehensive Home Inspection
A walk-around inspection each spring finds the gaps, standing water and nest sites that all three pests depend on. Look at the house the way a pest would: where could an ant get in, where does water collect, and where could a queen wasp start a nest?
Check window screens for tears, door thresholds and weather stripping for gaps, and exterior walls, the foundation and roof lines for cracks or damaged materials. Every Saela plan includes a 50+ point property inspection covering entry points, nesting sites and outdoor structures.
Creating a Pest-Resistant Environment
Reducing shelter and moisture around the foundation makes the whole property less inviting to ants, mosquitoes and wasps alike. Saela’s integrated pest management approach includes sealing entry points and reducing accessible food, water and shelter to address the conditions that support infestations.
Keep plantings trimmed back from the foundation, as UC IPM recommends for ants. Store firewood, building materials and garden equipment away from the house, and make sure water drains away from the foundation.
Beneficial Insects and Natural Predators
Natural predators can help with mosquitoes, but they work alongside water management, not instead of it. UF/IFAS Extension recommends planting native trees, shrubs and aquatic plants that support birds and dragonflies, which eat mosquitoes, and adding mosquito-eating fish to permanent water features such as ornamental ponds.
Avoid broad spraying that also kills beneficial insects, and leave harmless wasp nests far from people alone when it is safe to do so, since many wasps feed on other insects. Targeted treatment, aimed at the pest and the place it lives, is the core of integrated pest management.
Kitchen and Food Storage Pest Prevention
Pantry Protection Strategies
Sealed storage is the most useful pantry habit in summer, because it takes away the food that draws ants indoors. Opened packages and paper bags are easy for small ants to get into, and an open bag gives a trail a reason to keep coming back.
Store flour, sugar, cereal, pasta and pet food in clean, sealed containers, following UC IPM’s advice to avoid plastic bags or open packaging. Wipe pantry shelves regularly, paying attention to the cracks and corners where crumbs collect.
Refrigerator and Countertop Management
Quick cleanup matters most in warm weather, when foraging ants find sugary spills quickly. Wipe up spills right away, especially juice, soda and syrup, and don’t leave dirty dishes or pet food bowls out overnight.
Keep ripe fruit in the refrigerator during ant season, rinse cans and bottles before they go into the recycling bin, and take out kitchen trash often. Wiping counters with soapy water also removes the scent trails ants follow, as UC IPM notes.
Professional Pest Control Considerations
When to Call the Professionals
Call a professional when prevention isn’t keeping up or when the risk is high, such as a wasp nest near the house or someone in the household who is allergic to stings. Professional help also makes sense when you can’t find where ants are nesting.
The CDC recommends hiring a pest control professional to treat inside your home when mosquito problems persist indoors. Consider professional help when:
- You’ve found a wasp or yellowjacket nest near a door, walkway or play area, or inside a wall
- Ants keep returning after you’ve cleaned up and sealed entry points
- Mosquitoes remain heavy after you’ve removed standing water
- Someone in the household is allergic to insect stings
Choosing Effective and Safe Professional Services
Choose a provider that identifies the pest, explains why it is there and targets treatment, rather than one that sprays the same way on every visit. Ask how it finds entry points and nest sites, and what it will change about the conditions that drew the pests in.
Ask what preparation is needed before a visit and when it is safe to use treated areas again; preparation and re-entry should follow the product label and the licensed technician’s instructions. Saela quotes pest control based on pest type, location, property size, visit frequency and treatment products, so see how Saela’s plans and pricing work before comparing quotes.
How Saela Helps With Summer Pests
Saela uses an integrated pest management cycle of pest identification, activity monitoring, targeted treatment and evaluation, with adjustments based on the results. That cycle fits summer pests well, because ants, mosquitoes and wasps each need a different response once they are identified.
Dennis Weiss, Saela’s board-certified entomologist, develops its pest-control protocols, trains technicians and conducts service-quality audits.
Between scheduled services, Saela offers no-charge return visits for covered pests. In a July 2019 Google review, Anne DeBrie wrote, “They showed up when they said they would. They got rid of our ants.”
Frequently Asked Questions
How often should I inspect my home for signs of summer pests?
Check for standing water once a week, as the CDC recommends, and look over kitchens, entry points and outdoor gathering areas at the same time. Check eaves, sheds and play equipment for new wasp nests every few weeks in spring and early summer.
Are natural pest deterrents as effective as chemical treatments?
Cleaning, sealing and removing standing water are the most effective low-toxicity steps, and they work for prevention and small problems. Planting so-called repellent plants gives minimal protection against mosquitoes, according to UF/IFAS Extension, and established ant colonies or wasp nests may need targeted professional treatment.
How can I protect my pets from summer pests?
Ask your veterinarian about flea, tick and mosquito preventives for your pets. Bring pet food in or cover it, since UC IPM notes that scavenging yellowjackets show up at pet food dishes left outside, and empty and refill outdoor water dishes often so they don’t hold standing water.
What should I do if someone in my family is allergic to wasp stings?
Have any wasp nest near the house removed by a professional rather than trying it yourself. The CDC’s guidance on stinging insects notes that people who are allergic to venom may experience anaphylaxis, a potentially life-threatening reaction that requires immediate emergency care, and that people with a history of severe reactions should carry an epinephrine auto-injector.
How can I enjoy outdoor dining without attracting wasps?
Keep food covered until it is served, cover soda cans so wasps can’t crawl inside, and clean up spills right away, as UC IPM advises. Use garbage cans with tight-fitting lids, and consider yellow lure traps along the edge of the property, away from the table.
