Many wasp species are looking for a warm and secure place to build their nest. Unfortunately, that secure spot could end up being in your walls, behind the siding, or even in the attic. Once this happens, the likelihood of wasp issues inside the house gets bigger. Knowing the signs that wasps may move into your home can help you plan for a professional wasp treatment before these insects become too big of a pest.
1. Increased Activity
Keep an eye on the wasp activity around your home whenever you are outside. If you notice increased wasp activity along an eave or near an attic vent, you may have wasps that are either actively nesting or looking for a nesting spot. If the activity persists for more than a few hours or for multiple days, it's time to have the area inspected to see if wasps are nesting.
2. Obvious Flight Paths
Wasps tend to follow the same rough flight path when they are coming and going from their nest. This is especially true for nests in an attic or behind a siding panel since there will likely be only one entrance and exit. If you notice the pests bee-lining to the same soffit vent along the roofline, for example, then chances are they returning to a hidden nest that is on or in your home.
3. External Nests
Wasps don't always actually make it into your home, but if they are nesting nearby when winter comes, they may move indoors to where it is warmer and drier. This is why indoor wasp activity may increase as fall approaches—the pests are looking for a warmer and drier home. Walk the perimeter of your home and check the underside of roof eaves, window frames, and porch covers for any developing wasp nests. Have them removed before they become a problem.
4. Trapped Insects
Wasps rarely get into the home if you keep doors shut and window screens in good condition. If you keep finding wasps indoors, then you may be dealing with a nest in the attic or in the walls. You may mainly notice wasps inside in the early spring when they are nesting inside, which is due to the fact that they are coming out of the nest for the new season and becoming confused so that they end up in your main living area instead of making their way outside.
Contact a wasp pest control service if you suspect that these stinging insects have made their way into your home.
