Current Pest Advisory for Old Town Calabasas (August 2026)

As we're in the thick of August's dry heat, Old Town Calabasas is seeing a spike in two specific pests: roof rats and German cockroaches. The historic adobes and multi-unit buildings along the creek corridor provide perfect harborage for roof rats, who are actively seeking water and food sources. With the Calabasas Creek running year-round, these rodents have a reliable water source and travel along the riparian zone, easily accessing attics and eaves of older structures like those near the Leonis Adobe. Meanwhile, the commercial kitchens and outdoor dining areas at The Commons are a magnet for German cockroaches, which thrive in the warm, humid microclimates created by food waste and irrigation runoff. The shared walls in mixed-use buildings allow roaches to move freely between units, making infestations spread quickly.

Homeowners should be on the lookout for rat droppings (dark, rice-sized pellets) in garages, attics, or along fence lines, as well as gnaw marks on utility lines or fruit trees. For cockroaches, check behind refrigerators, under sinks, and in bathroom cabinets for small, pepper-like feces or shed wings. Also, listen for scratching sounds in walls at night—a classic sign of roof rats. Given the historic nature of many properties, sealing gaps around pipes and rooflines is crucial. Below are the top-rated Calabasas exterminators who specialize in these specific seasonal threats.

Wasp Nest Removal in Old Town Calabasas: Identification & Prevention Guide

Did you know that in Southern California, wasp-related emergency room visits spike by over 40% during the warm months from May to October? In Old Town Calabasas, where the Mediterranean climate brings hot, dry summers and mild winters, wasps are a year-round concern, but activity peaks when temperatures rise. Whether you’re enjoying a patio in the historic district or tending to your garden in a nearby home, knowing how to spot and handle a wasp nest is key to staying safe.

This guide focuses on identification first—because the right approach depends on the type of wasp. In Old Town Calabasas, you’ll likely encounter yellowjackets or paper wasps. Yellowjackets build nests underground or in wall voids, while paper wasps create open, umbrella-shaped nests under eaves or in bushes. Look for increased wasp activity around food sources like trash bins or outdoor dining areas, especially during late summer when colonies are largest. Nests can appear as gray, papery structures or hidden in ground holes. Never approach a nest without proper protection; instead, observe from a distance to confirm its location.

Removal is best done at dusk when wasps are less active, but if the nest is large or in a tricky spot (like inside a wall), it’s safer to leave it alone. Simple steps like sealing cracks, removing fallen fruit, and keeping garbage lids tight can discourage nesting. For nests in high-traffic areas, your safest bet is to wait until winter when the colony dies off naturally—then remove the empty nest. Remember, wasps are beneficial pollinators, so consider leaving solitary nests alone if they’re out of the way.

In Old Town Calabasas, wasp nest management is about smart identification and timing. Recognize the nest type—paper wasp (open comb) vs. yellowjacket (hidden)—and watch for increased activity in warm months. Prevention through sanitation and exclusion is your best defense. For active nests near living areas, removal should be done carefully at dusk or by waiting for winter die-off. Always prioritize safety: never block a nest entrance, and avoid DIY removal of large or inaccessible nests. This educational guide provides the knowledge you need to coexist safely with these stinging insects in your Calabasas neighborhood.

Frequently Asked Questions About Wasp Nest Removal in Old Town Calabasas

Q: How can I tell if I have a wasp nest in Old Town Calabasas?

Look for wasps flying in a steady line to and from a specific spot—like under eaves, in bushes, or near ground holes. Paper wasp nests are open, umbrella-shaped combs; yellowjacket nests are often hidden in wall voids or underground. Also check for chewed wood (papery material) near eaves or fences.

Q: What time of year are wasps most active in Calabasas?

Wasp activity peaks from late spring through early fall (May to October), with colonies largest in late summer. However, due to the mild climate, some wasps remain active year-round, especially on warm winter days.

Q: Should I remove a wasp nest myself?

Small, exposed paper wasp nests can be removed at dusk with caution—wear thick clothing and use a long stick to knock it down. But avoid DIY removal for large nests, hidden nests (inside walls), or if you’re allergic. Ground nests often require professional handling.

Q: How do I prevent wasps from nesting in my Calabasas home?

Seal cracks in walls, eaves, and foundations. Keep trash cans tightly covered, clean up fallen fruit, and avoid leaving pet food outside. Also, consider planting wasp-repelling plants like mint or marigolds around patios.

Q: Are wasps dangerous in Old Town Calabasas?

Wasps can sting multiple times and are aggressive when defending their nest. For most people, stings cause pain and swelling, but for those allergic, they can be life-threatening. Avoid swatting or disturbing nests, and keep children and pets away.
